# spliti

(PHP 4 >= 4.0.1, PHP 5)

spliti — Split string into array by regular expression case insensitive

### Description

array spliti ( string `$pattern` , string `$string` [, int `$limit` ] )

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", $string, 5);
print_r($chunks);
?>`

The above example will output:

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