First of all, as per extensive discussion on the list, the functions are now
prefixed with "preg" instead of "pcre".
Secondly, global matching is now possible using preg_match_all. Please, give
suggestions on a better name if this one doesn't sit well with you. Possible
names are preg_global_match and preg_gmatch.
preg_match_all takes 4 arguments: a regex pattern, a subject string,
the array for capturing subpatterns, and a parameter that tells how the results
in the subpatterns array are arranged.
Basically, preg_match_all will go through the subject string and try to capture
all the matches that it finds, not just the first one like preg_match.
4th parameter can be PREG_PATTERN_ORDER (default) or PREG_SET_ORDER.
Example:
preg_match_all("|</?([^>]+)>|", "<div align=left>a test</div>", $out, PREG_PATTERN_ORDER);
This returns results so that $out[0] is an array of full pattern matches, $out[1] is an array
of first captured subpattern matches, and so on.
$out[0] -> ("<div align=left>", "</div>")
$out[1] -> ("div align=left", "div")
Example:
preg_match_all("|</?([^>]+)>|", "<div align=left>a test</div>", $out, PREG_SET_ORDER);
This returns results so that $out[0] is an array of first full pattern match and subpatterns,
$out[1] is an array of second full pattern match and subpatterns.
$out[0] -> ("<div align=left>", "div align=left")
$out[1] -> ("</div>", "div")
If anyone has a better name for these PREG_ constants and also which one should be the default,
I'd like to hear it.
PCRE library can be found at ftp://ftp.cus.cam.ac.uk/pub/software/programs/pcre/
config.m4 will be updated to be more robust later on.
perl_match() takes a regular expression, the source string, and the array
for subpattern matches.
perl_replace() takes a regular expression, the search string, and the replacement
string.
Regular expression is specified using delimiters and options. Example:
perl_match("/<[a-z]*>/i", $text, $tags);
More stuff is coming soon.
the way you intended it to be? How does the basic_functions module get in there?
* Fix to get MySQL objects working, even though I'll probably make a dedicated
MySQL object in the future.
* There are now -I directives for the absolute path of php4, php4/libzend and the builddir for
the Apache module, so we can #include any php/Zend header.
* Rename config.h to php_config.h
* Fully implement ISAPI support - POST and cookies among other things.
* Almost completely rewrote phpinfo(). Allow modules to easily display their
information in phpinfo() without modifying phpinfo() itself (prototype for
the module info function was changed, thus the large amount of updated module
files).
* Initial extended SAPI support for Apache, completely untested.
* CGI now uses SAPI fully as well.
