Description
array
explode ( string delimiter, string string [, int limit] )
Returns an array of strings, each of which is a substring of
string formed by splitting it on
boundaries formed by the string delimiter.
If limit is set, the returned array will
contain a maximum of limit elements with
the last element containing the rest of
string.
If delimiter is an empty string (""),
explode() will return FALSE. If
delimiter contains a value that is not contained
in string, then explode() will
return an array containing string.
If the limit parameter is negative, all components
except the last -limit are returned. This feature
was added in PHP 5.1.0.
Although implode() can, for historical reasons,
accept its parameters in either order,
explode() cannot. You must ensure that the
delimiter argument comes before the
string argument.
Note:
The limit parameter was added in PHP
4.0.1
Example 1. explode() examples
<?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; // *
?>
|

Example 2. limit parameter examples
<?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
) |
