PHP string Split function split

Description

array Split (string $pattern , string $string [, int $limit ])

This function returns an array of strings, each of which is a string with a case-sensitive regular expression pattern as a substring of the boundary. If limitis set, the returned array contains a maximum of limit cells, and the last cell contains all the remaining parts of the string . If there is an error, split () returns FALSE.

Example #1 Split () Example

<?php
list ( $user ,&NBSP; $pass ,&NBSP; $uid ,  $gid ,&NBSP; $extra      SPLIT&NBSP; ( ,  $passwd _line ,&NBSP; 5 );
?>

If there are n items in a string that match pattern , the returned array will contain n+1 cells. For example, if patternis not found, an array with only one cell is returned. Of course, this is true if the string is empty.

Example #2 Split () Example

<?php
//delimiter can be a slash, dot, or horizontal line
$date= "04/30/1973";
List ($month, $day, $year) = Split(' [/.-] ', $date);
Echo"Month:$month; Day:$day; Year:$year<br/> ";
?>

Note that pattern is a regular expression. If you want to use a split character that is a special character in a regular expression, first escape it.
