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.
If there are
n occurrences of
pattern, the returned array will contain
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,
This example splits a string using 'a' as the separator :
$string = "aBBBaCCCADDDaEEEaGGGA";
$chunks = spliti ("a", $string, 5);
The above example will output:
 => BBB
 => CCC
 => DDD
 => EEEaGGGA
