Bug description: the pcre (preg_*) functions should be able to pre-compile
regexps
Description:
------------
what I'm proposing is, adding a function (perhaps named preg_compile) that
would accept 1 string parameter $pattern.
the function would return a resource with the compiled pcre code which
could be used anywhere in the other preg_* functions where a string for the
pattern would be accepted.
this way if you need to do 1000s of pcre matches of the same pattern(s) on
different data, it would not require internally doing pcre_compile() over
and over, saving very valuable cpu time.
Reproduce code:
---------------
<?php
$pattern = preg_compile("/s[i1]mpl[e3] pattern here/i"); // returns a new
type of resource
if (preg_match($pattern, "simple pattern here")) // which can then be used
anywhere the normal string pattern could be
echo "pattern matches\n";
?>
Expected result:
----------------
well, obviously if this feature was added i'd expect to see:
pattern matches
Actual result:
--------------
since this is not actually implemented i'd just get a fatal error :P
