Hello there Zubin,

There are a lot of ways to get what you want. All you need to do is to familiarize the string methods available in php. You may try the following methods that I define next to this.

Using strpos() or stripos()

if(stripos($text, "world") !== false) {

    echo "True";

}

Using strstr() or stristr()

if(strstr($text,"world"))   

{

echo "True";

}

You may use these methods but it is more convenient to use strpos() if you want to find the text because it can give less trouble.

Regards Ronald

Hello Zubin Lennon, 

This might be what you are looking for:
 
<?php
 
$text = 'This is a Simple text.';
 
// this echoes "is is a Simple text." because 'i' is matched first
echo strpbrk($text, 'mi');
 
// this echoes "Simple text." because chars are case sensitive
echo strpbrk($text, 'S');
?>
 
Is it?
 
Or maybe this:
 
<?php
$mystring = 'abc';
$findme   = 'a';
$pos = strpos($mystring, $findme);
 
// Note our use of ===.  Simply == would not work as expected
// because the position of 'a' was the 0th (first) character.
if ($pos === false) {
    echo "The string '$findme' was not found in the string '$mystring'";
} else {
    echo "The string '$findme' was found in the string '$mystring'";
    echo " and exists at position $pos";
}
?>
 
Or even this
 
<?php
$email  = '[email protected]';
$domain = strstr($email, '@');
echo $domain; // prints @example.com
 
$user = strstr($email, '@', true); // As of PHP 5.3.0
echo $user; // prints name
?>
 
You can read all about them in the documentation here:
