PREG_SPLIT_DELIM_CAPTURE does not work - preg_split() simply omits the delimiters disregarding the flag.

The following line:

print_r(preg_split('/a/', 'mama', -1, PREG_SPLIT_DELIM_CAPTURE));


    [0] => m
    [1] => m
    [2] => 

...just like without the last argument - while it should return:

    [0] => m
    [1] => a
    [2] => m
    [3] => a
    [4] =>

Read the manual:


If this flag is set, parenthesized expression in the delimiter pattern will be captured and returned as well. This flag was added for 4.0.5.

So your pattern should look like:

and presto, it works.

It will be a nice idea to put this example to documentation; I was already going to send a bug report about PREG_SPLIT_DELIM_CAPTURE when I found this article.

very useful information, please add to documentation or highlight the phrase "parenthesized expression". Thanks.
