Warning

Alternatives to this function include:

Description

array spliti ( string $pattern , string $string [, int $limit = -1 ] )

Splits a string into array by regular expression.

This function is identical to split() except that this ignores case distinction when matching alphabetic characters.

Parameters

pattern

Case insensitive regular expression.

If you want to split on any of the characters which are considered special by regular expressions, you'll need to escape them first. If you think spliti() (or any other regex function, for that matter) is doing something weird, please read the file regex.7, included in the regex/ subdirectory of the PHP distribution. It's in manpage format, so you'll want to do something along the lines of man /usr/local/src/regex/regex.7 in order to read it.

string

The input string.

limit

If limit is set, the returned array will contain a maximum of limit elements with the last element containing the whole rest of string.

Return Values

Returns an array of strings, each of which is a substring of string formed by splitting it on boundaries formed by the case insensitive regular expression pattern.

If there are n occurrences of pattern, the returned array will contain n+1 items. For example, if there is no occurrence of pattern, an array with only one element will be returned. Of course, this is also true if string is empty. If an error occurs, spliti() returns FALSE.

Examples

This example splits a string using 'a' as the separator :

Example #1 spliti() example

<?php
$string 
"aBBBaCCCADDDaEEEaGGGA";
$chunks spliti ("a"$string5);
print_r($chunks);
?>

The above example will output:

Array
(
  [0] =>
  [1] => BBB
  [2] => CCC
  [3] => DDD
  [4] => EEEaGGGA
)
