spliti — Split string into array by regular expression case insensitive
$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.
This function has been DEPRECATED as of PHP 5.3.0. Relying on this feature is highly discouraged.
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.
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.
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 )
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.
