$content=explode($end,$content[1]); 
return $content[0];

explode definition and usage
explode() function splits a string into an array.

Syntax

explode(separator,string,limit)

Parameters	Description
separator	Required. Specifies where to split the string.
string	Required. The string to split.
limit	Optional. Specifies the maximum number of array elements returned.

Explanation
This function returns an array composed of strings, each element of which is a substring separated by separator as a boundary point .

separator parameter cannot be an empty string. If separator is the empty string (""), explode() returns FALSE. If separator contains a value that is not found in string, explode() returns an array containing a single element from string.

If the limit parameter is set, the returned array contains at most limit elements, and the last element will contain the remainder of the string.

If the limit parameter is a negative number, all elements except the last -limit elements are returned. This feature is new in PHP 5.1.0.
Tips and Notes
Note: The parameter limit was added in PHP 4.0.1.

Note: Due to historical reasons, although implode() can receive two parameter orders, explode() cannot. You must ensure that the separator parameter comes before the string parameter.

Example
In this example, we will split the string into an array:

The code is as follows:

<?php 
$str = "Hello world. It&#39;s a beautiful day."; 
print_r (explode(" ",$str)); 
?>

Output:

Array 
( 
[0] => Hello 
[1] => world. 
[2] => It's 
[3] => a 
[4] => beautiful 
[5] => day. 
)
