Returns an array of strings, each of which is a substring of string
formed by splitting it on boundaries formed by the string delimiter
.
The boundary string.
The input string.
If limit
is set and positive, the returned array will contain a maximum of limit
elements with the last element containing the rest of string
.
If the limit
parameter is negative, all components except the last -limit
are returned.
If the limit
parameter is zero, then this is treated as 1.
Returns an array of strings created by splitting the string
parameter on boundaries formed by the delimiter
.
If delimiter
is an empty string (""), explode() will return FALSE
. If delimiter
contains a value that is not contained in string
and a negative limit
is used, then an empty array will be returned, otherwise an array containing string
will be returned.
Support for negative limit

<?php // Example 1 $pizza = "piece1 piece2 piece3 piece4 piece5 piece6"; $pieces = explode(" ", $pizza); echo $pieces[0]; // piece1 echo $pieces[1]; // piece2 // Example 2 $data = "foo:*:1023:1000::/home/foo:/bin/sh"; list($user, $pass, $uid, $gid, $gecos, $home, $shell) = explode(":", $data); echo $user; // foo echo $pass; // * ?>
<?php /* A string that doesn't contain the delimiter will simply return a one-length array of the original string. */ $input1 = "hello"; $input2 = "hello,there"; var_dump( explode( ',', $input1 ) ); var_dump( explode( ',', $input2 ) ); ?>
The above example will output:
array(1) ( [0] => string(5) "hello" ) array(2) ( [0] => string(5) "hello" [1] => string(5) "there" )
<?php $str = 'one|two|three|four'; // positive limit print_r(explode('|', $str, 2)); // negative limit (since PHP 5.1) print_r(explode('|', $str, -1)); ?>
The above example will output:
Array ( [0] => one [1] => two|three|four ) Array ( [0] => one [1] => two [2] => three )
