Reported By: daniel@lorch.cc
Status: Open
-Bug Type: PCRE related
+Bug Type: Documentation problem
Operating System: Linux
PHP Version: 4.1.2
New Comment:
pcre is binary safe with regards to the string being matched against,
but not the pattern. this is a limitation of the pcre library itself,
not just the php interface. you can specify the nul character using:
preg_match("/\\x00/", "foo\0bar")
reclassified as documentation problem.

The docs state that PCRE is binary safe. So this might be a bug after
all...

Actually, I'm not sure whether this problem can be solved as it is PCRE
and not a PHP specific (and it can't be solved without breaking
compatibilty with languages using 0 terminated strings such as C).
I'm thinking about making it a documentation problem. What do you guys
think?

The PCRE has problems with strings containing 0x00. It stops reading as
if the strings were \0 terminated. This affects all preg_* functions.
Examples:
preg_match("/\x00/", "foo");
preg_match("/" . chr(0) . "/", "foo");
Raises the error "Warning: No ending delimiter '/' found"
