spliti - Split string into array by regular expression case insensitive

SYNOPSIS

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

DESCRIPTION

	Splits a $string into array by regular expression.

	This function is identical to split(3) except that this ignores case distinction when matching alphabetic characters.

       Warning

	      This function has been DEPRECATED as of PHP 5.3.0. Relying on this feature is highly discouraged.

PARAMETERS

	      o $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(3) (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 for-
		mat, so you'll want to do something along the lines of man /usr/local/src/regex/regex.7 in order to read it.

	      o $string
		- The input string.

	      o $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(3) returns
       FALSE.

EXAMPLES

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

       Example #1

	      spliti(3) 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
	      )

NOTES

       Note

	      As of PHP 5.3.0, the regex extension is deprecated in favor of the PCRE extension. Calling this function will issue an  E_DEPRECATED
	      notice. See the list of differences for help on converting to PCRE.

       Tip

	      spliti(3) is deprecated as of PHP 5.3.0. preg_split(3) with the i ( PCRE_CASELESS) modifier is the suggested alternative.
