PCRE question

Hello,

It was my understanding that when the PCRE module was loaded in php
that constants would be available that were built in to that module.
For example, I need to use some flags with my regular expression, but
they don't seem to be loaded. Here's an example:

var_dump(PCRE_M ULTILINE);
var_dump(PCRE_D OTALL);
var_dump(PCRE_M ULTILINE | PCRE_DOTALL);

the lines above produce this output

string(14) "PCRE_MULTILINE "
string(11) "PCRE_DOTAL L"
string(14) "PCRE_M_\UMLINE "

Shouldn't those be long values rather than string values?

Could there be a configuration problem with my WAMP test environment?

Thanks,
Daniel

Yes, it seems you haven't enabled the error reporting. Find your php.ini
file and set these values:

display_errors = On
error_reporting = E_ALL | E_STRICT
According to the PHP manual all the constants of the extension begin with
PREG_* so you should get a notice about undefined constants:

Hi all, I am a beginner on 'c' and pcre...and I am on windows 2000 and VC6 with all of the patches, etc. The following program leaks lots of memory and I only make 1 pcre call. I read the docs, but maybe I missed some cleanup or other calls??? Or maybe I messed up passing strings around???
