Sending Mails with Attachment in PHP

Here is the code for sending for mails with Attachments in PHP.

$email_from = "Anil Kumar"; // Who the email is from
$email_subject = "Email with Attachment"; // The Subject of the email
$email_message = "Is the File Attached."; // Message that the email has in it

$email_to = "anilbuddha@gmail.com"; // Who the email is too

$headers = "From: ".$email_from;


$semi_rand = md5(time());
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";

$headers .= "\nMIME-Version: 1.0\n" .
"Content-Type: multipart/mixed;\n" .
" boundary=\"{$mime_boundary}\"";

$email_message .= "This is a multi-part message in MIME format.\n\n" .
"--{$mime_boundary}\n" .
"Content-Type:text/html; charset=\"iso-8859-1\"\n" .
"Content-Transfer-Encoding: 7bit\n\n" .
$email_message . "\n\n";

/********************************************** First File ********************************************/


$fileatt = "../reports/users.pdf"; // Path to the file
$fileatt_type = "application/pdf"; // File Type
$fileatt_name = "users"; // Filename that will be used for the file as the attachment

$file = fopen($fileatt,'rb');
$data = fread($file,filesize($fileatt));
fclose($file);


$data = chunk_split(base64_encode($data));

$email_message .= "--{$mime_boundary}\n" .
"Content-Type: {$fileatt_type};\n" .
" name=\"{$fileatt_name}\"\n" .

$ok = mail($email_to, $email_subject, $email_message, $headers);

if($ok) {
echo "Email With Attachment has been Sent Successfully";
} else {
echo "Sending Email with Attachment has Failed. Please check the Code Added";
}

This can be done in our local system but when we need this is in Server where our Project is maintained it is not possible. So here is the Rewrite Rule in HTACCESS for PHP where we can change the maximum file size limit.

Rewrite Rule for Maximum File size is shown below.

php_value upload_max_filesize 20M

Date Validation using Javascript

Here is the validation for date using javascript.

var dtCh= "/";
var minYear=1900;
var maxYear=2100;

function isInteger(s){
    var i;
    for (i = 0; i < s.length; i++){  
        // Check that current character is number.
        var c = s.charAt(i);
        if (((c < "0") || (c > "9"))) return false;
    }
    // All characters are numbers.
    return true;
}

function stripCharsInBag(s, bag){
    var i;
    var returnString = "";
    // Search through string's characters one by one.
    // If character is not in bag, append to returnString.
    for (i = 0; i < s.length; i++){  
        var c = s.charAt(i);
        if (bag.indexOf(c) == -1) returnString += c;
    }
    return returnString;
}

function daysInFebruary (year){
    // February has 29 days in any year evenly divisible by four,
    // EXCEPT for centurial years which are not also divisible by 400.
    return (((year % 4 == 0) && ( (!(year % 100 == 0)) || (year % 400 == 0))) ? 29 : 28 );
}
function DaysArray(n) {
    for (var i = 1; i <= n; i++) {
        this[i] = 31;
        if (i==4 || i==6 || i==9 || i==11) {this[i] = 30;}
        if (i==2){this[i] = 29;}
   }
   return this;
}

function isDate(dtStr){
    var daysInMonth = DaysArray(12);
    var pos1=dtStr.indexOf(dtCh);
    var pos2=dtStr.indexOf(dtCh,pos1+1);
    var strMonth=dtStr.substring(0,pos1);
    var strDay=dtStr.substring(pos1+1,pos2);
    var strYear=dtStr.substring(pos2+1);
    strYr=strYear;
    if (strDay.charAt(0)=="0" && strDay.length>1) strDay=strDay.substring(1);
    if (strMonth.charAt(0)=="0" && strMonth.length>1) strMonth=strMonth.substring(1);
    for (var i = 1; i <= 3; i++) {
        if (strYr.charAt(0)=="0" && strYr.length>1) strYr=strYr.substring(1);
    }
    month=parseInt(strMonth);
    day=parseInt(strDay);
    year=parseInt(strYr);
    if (pos1==-1 || pos2==-1){
        alert("The date format should be : mm/dd/yyyy");
        return false;
    }
    if (strMonth.length<1 || month<1 || month>12){
        alert("Please enter a valid month");
        document.form1.month.focus();
        return false;
    }
    if (strDay.length<1 || day<1 || day>31 || (month==2 && day>daysInFebruary(year)) || day > daysInMonth[month]){
        alert("Please enter a valid day");
        document.form1.day.focus();
        return false;
    }
    if (strYear.length != 4 || year==0 || year<minYear || year>maxYear){
        alert("Please enter a valid 4 digit year between "+minYear+" and "+maxYear);
        return false;
    }
    if (dtStr.indexOf(dtCh,pos2+1)!=-1 || isInteger(stripCharsInBag(dtStr, dtCh))==false){
        alert("Please enter a valid date");
        return false;
    }
    return true;
}

To check the given string is a Date or not, the date format should be checked as shown below.

var dt = document.form1.month.value +'/' +document.form1.day.value +'/'+ document.form1.year.value;
    if (isDate(dt)==false){
        return false;
    }

The date format to be passed is MM/DD/YYYY.

PHP Interview Questions and Answers

Here are some of the PHP interview Questions with answers which may help you.

1. What are the differences between GET and POST methods in form submitting, give the case where we can use get and we can use post methods?
Answer: On the server side, the main difference between GET and POST is where the submitted is stored. The $_GET array stores data submitted by the GET method. The $_POST array stores data submitted by the POST method.
On the browser side, the difference is that data submitted by the GET method will be displayed in the browser's address field. Data submitted by the POST method will not be displayed anywhere on the browser.
GET method is mostly used for submitting a small amount and less sensitive data. POST method is mostly used for submitting a large amount or sensitive data.


2. Who is the father of php and explain the changes in php versions?
Answer:  Rasmus Lerdorf for version changes go to http://php.net/
Marco Tabini is the founder and publisher of php|architect.

3. How can we submit from without a submit button?
Answer: We can use a simple JavaScript code linked to an event trigger of any form field.
In the JavaScript code, we can call the document.form.submit() function to submit the form.

 4. How many ways we can retrieve the date in result set of mysql Using php?
Answer: As individual objects so single record or as a set or arrays.

5. What is the difference between mysql_fetch_object and mysql_fetch_array?
Answer:  MySQL fetch object will collect first single matching record where mysql_fetch_array will collect all matching records from the table in an array.

6. What is the difference between $message and $$message?
Answer: They are both variables. But $message is a variable with a fixed name. $$message is a variable who's name is stored in $message. For example, if $message contains "var", $$message is the same as $var.

7. How can we extract string 'abc.com ' from a string 'http://info@a...' using regular _expression of php?
Answer: We can use the preg_match() function with "/.*@(.*)$/" as
the regular expression pattern. For example:
preg_match("/.*@(.*)$/","http://info@abc.com",$data);
echo $data[1];

8. How can we create a database using php and mysql?
Answer: PHP: mysql_create_db()
Mysql: create database;

9. What are the differences between require and include, include_once?
Answer: File will not be included more than once. If we want to include a file once only and further calling of the file will be ignored then we have to use the PHP function include_once(). This will prevent problems with function redefinitions, variable value reassignments, etc.

10. Can we use include ("abc.php") two times in a php page "makeit.php"?
Answer: Yes we can include..

11. What are the different tables present in mysql, which type of table is generated when we are creating a table in the following

1. MyISAM
2. Heap
3. Merge
4. InnoDB
5. ISAM
6. BDB
MyISAM is the default storage engine as of MySQL 3.23.

12. Functions in IMAP, POP3 AND LDAP?
Answer:  Please visit:
http://fi2.php.net/imap
http://uk2.php.net/ldap

13. How can I execute a php script using command line?
Answer: Just run the PHP CLI (Command Line Interface) program and provide the PHP script file name as the command line argument. For example, "php myScript.php", assuming "php" is the command to invoke the CLI program. Be aware that if your PHP script was written for the Web CGI interface, it may not execute properly in command line environment.

14. Suppose your ZEND engine supports the mode <? ?> Then how can u configure your php ZEND engine to support <?php ?> mode ?
Answer: If you change the line: short_open_tag = off in php.ini file. Then your php ZEND engine support only <?php ?> mode.

15. Shopping cart online validation i.e. how can we configure the paypals?

16. What is meant by nl2br()?
Answer: nl2br -- Inserts HTML line breaks before all newlines in a string
string nl2br (string); Returns string with '<br />' inserted before all newlines.
For example: echo nl2br("god bless\n you") will output "god bless
\n you" to your browser.

Function for taking MySQL Backup in PHP

Here is the function for taking backup of a MySQL database without any external tool for MySQL.

$host ---> Hostname
$user ----> Username
$pass ----> Password
$name ----> Database name
If we need the total database, just put the value of $tables as * or else pass only the tables you want with comma separated.

function backup_tables($host,$user,$pass,$name,$tables = '*')
{

 $link = mysql_connect($host,$user,$pass);
 mysql_select_db($name,$link);

 //get all of the tables
 if($tables == '*')
 {
 $tables = array();
 $result = mysql_query('SHOW TABLES');
 while($row = mysql_fetch_row($result))
 {
 $tables[] = $row[0];
 }
 }
 else
 {
 $tables = is_array($tables) ? $tables : explode(',',$tables);
 }

 //cycle through
 foreach($tables as $table)
 {
 $result = mysql_query('SELECT * FROM '.$table);
 $num_fields = mysql_num_fields($result);

 //$return.= 'DROP TABLE '.$table.';';
 $row2 = mysql_fetch_row(mysql_query('SHOW CREATE TABLE '.$table));
 $return.= "\n\n".$row2[1].";\n\n";

 for ($i = 0; $i < $num_fields; $i++)

 $return.= 'INSERT INTO '.$table.' VALUES(';
 for($j=0; $j<$num_fields; $j++)

Happy Independence Day

Wish you all a Happy Independence Day........

Post your Status in Twitter using PHP

t$twitter_api_url = "http://twitter.com/statuses/update.xml";
$twitter_data = "status=Visit http://anilkajadoo.blogspot.com/ for PHP tips and tutorials!";
$twitter_user = "your_user_name";
$twitter_password = "your_password";

The $twitter_data variable contains the message to be posted to Twitter, which you must ensure is 140 characters or less before posting. You could use strlen() function to do so when you ready the data to be sent, and truncate it if it’s too long by using substr() function. The status= before the message is the POST variable, the parameter for the API.


To send the request, we will use cURL, which is included on most servers. First we initiate cURL and pass it the URL we will be sending the request to:

$ch = curl_init($twitter_api_url);

curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $twitter_data);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_USERPWD, "{$twitter_user}:{$twitter_password}");//Twitter Username & Password are used to post the status


$twitter_data = curl_exec($ch);
$httpcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);

All that’s left really is to see whether it worked or not. Since we have our handy $httpcode variable, we can just run a conditional statement to see if the response code is equal to 200 (which means everything went okay).

if ($httpcode != 200) {
     echo "The tweet wasn't posted correctly. ";
}

         

Create a Tiny URL using PHP

Function to create a tiny URL for the site using PHP....


function get_tiny_url($url){
    $ch = curl_init();
    $timeout = 5;
    curl_setopt($ch,CURLOPT_URL,'http://tinyurl.com/api-create.php?url='.$url);
    curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
    curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,$timeout);
    $data = curl_exec($ch);
    curl_close($ch);
    return $data;
}

//Test the Function.......

$new_url = get_tiny_url('http://anilkajadoo.blogspot.com/');

//The tinyURL has been generated & just print it below
echo $new_url;

$pattern = "|<[\s]*title[\s]*>([^<]+)<[\s]*/[\s]*title[\s]*>|Ui";
if(preg_match($pattern, $content, $match))
return $match[1];
else
return false;
}

$url = $siteurl; //Enter the Site URL which we want to get the Page Title
$content = file_get_contents($url);
$title = getMetaTitle($content);
$tags = get_meta_tags($siteurl); // To get the meta content, description, keywords of the given URL....


$tags is a array of all meta data
To get the Meta Keywords, Description we will use the get_meta_tags which is a predefined function in PHP. To retrieve the values we need to use $tags['keywords'] for Keywords & for Description $tag['description']

Showing Current Date & Time using Javascript

Insert the Below code anywhere into the body section where you need to see the Current date & time 

<script>

var dayarray=new Array("Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday")
var montharray=new Array("January","February","March","April","May","June","July","August","September","October","November","December")

function getthedate(){
var mydate=new Date()
var year=mydate.getYear()
if (year < 1000)
year+=1900
var day=mydate.getDay()
var month=mydate.getMonth()
var daym=mydate.getDate()
if (daym<10)
daym="0"+daym
var hours=mydate.getHours()
var minutes=mydate.getMinutes()
var seconds=mydate.getSeconds()
var dn="AM"
if (hours>=12)
dn="PM"
if (hours>12){
hours=hours-12
}
if (hours==0)
hours=12
if (minutes<=9)
minutes="0"+minutes
if (seconds<=9)
seconds="0"+seconds
//change font size here
var cdate="<small><font color='000000' face='Arial'><b>"+dayarray[day]+", "+montharray[month]+" "+daym+", "+year+" "+hours+":"+minutes+":"+seconds+" "+dn
+"</b></font></small>"
if (document.all)
document.all.clock.innerHTML=cdate
else if (document.getElementById)
document.getElementById("clock").innerHTML=cdate
else
document.write(cdate)
}
if (!document.all&&!document.getElementById)
getthedate()
function goforit(){
if (document.all||document.getElementById)
setInterval("getthedate()",1000)
}

</script>
<span id="clock"></span>

& in the Body tag, we need to add an onLoad Function as shown below.

<body onload="goforit()">

Loading Image Before the Page Loads using Javascript

Below is the code used to show the Loading image before the page loads.

To implement this you will need to:

1. Every time your page loads a "init()" function will load.

<body onLoad="init()">

2. Define a div named "loading" right after <body> section.

<div id="loading" style="position:absolute; width:100%; text-align:center; top:300px;">
<img src="loading.gif" border=0></div>

The loading.gif image should be an animated gif that suggests that the page is still loading.

3. Place this javascript code right after you define the div.

 <script>
 var ld=(document.all);
  var ns4=document.layers;
 var ns6=document.getElementById&&!document.all;
 var ie4=document.all;
  if (ns4)
  ld=document.loading;
 else if (ns6)
  ld=document.getElementById("loading").style;
 else if (ie4)
  ld=document.all.loading.style;
  function init()
 {
 if(ns4){ld.visibility="hidden";}
 else if (ns6||ie4) ld.display="none";
 }
 </script>
