explode() :
Split a string by
string.
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.
Parameters
delimiter -
The
boundary string.
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.
Return Values
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.
Example :
<?php
$array = array('lastname', 'email', 'phone');
$comma_separated = implode(",", $array);
echo $comma_separated; // lastname,email,phone
// Empty string when using
an empty array:
var_dump(implode('hello', array())); // string(0) ""
?>
Example : limit parameter examples.
<?php
$str =
'one|two|three|four';
// positive limit
print_r(explode('|',
$str, 2));
?>
Output :
Array
(
[0] => one
[1] => two|three|four
)
