$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.
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.
The input string.
If limit is set, the returned array will
contain a maximum of limit elements with the
last element containing the whole rest of
string.
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.
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 )
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_DEPRECATEDnotice. See the list of differences for help on converting to PCRE.
spliti() is deprecated as of PHP 5.3.0. preg_split()
with the i (PCRE_CASELESS) modifier is the suggested alternative.
