Description:
------------
Hi,

the documentation of preg_match_all seems to be corrupt.

In the *Parameters* section the description for *matches* says:

"matches

    In this case, $matches[0] is the first set of matches, and $matches[0][0] has text matched by full pattern, $matches[0][1] has text matched by first subpattern and so on. Similarly, $matches[1] is the second set of matches, etc. "

This applies only when the flag PREG_SET_ORDER is set (non-default).

The beginning "In this case" without giving information about which case is meant indicates that there is something missing. The correct documentation could be like written here in the field "Expected result".

Thanks,

Johannes Ponader


Expected result:
----------------
matches

By default, $matches[0] is an array of full pattern matches, $matches[1] is an array of strings matched by the first parenthesized subpattern, and so on. $matches[0][0] is the first match of the full pattern, $matches[0][1] is the second match etc.. $matches[1][0] is the first match of the first subpattern.

If the Flag PREG_SET_ORDER is set, the array is ordered differently. In this case... 

(continues like in actual version)



Actual result:
--------------
matches

    In this case, $matches[0] is the first set of matches, and $matches[0][0] has text matched by full pattern, $matches[0][1] has text matched by first subpattern and so on. Similarly, $matches[1] is the second set of matches, etc.
