RE: [PHP] Comparing files
Yes!
Thanks a lot, "md5_file" suits perfectly well my needs.
I've read that 'exec'ing the md5 command is faster... I'll see when performance
on large files will become an issue.
Thanks again,

You could use "md5_file" for this. Something like:
function files_identical($path1, $path2) {
return (md5_file($path1) == md5_file($path2));
}

[PHP] Comparing files
Hi all,
I have a simple question : how can I ensure that 2 files are identical ?
How about this ?
8<--
function files_identical($path1, $path2) {
return (file_get_contents($path1) == file_get_contents($path2));
}
8<--
Note that I would like to compare any type of files (text and binary).
Thanks for any help,

Yes Jochem, I *now* know what "lookbehind" and "lookahead" assertions are. I think I am *now* able to use them when needed.

Mathieu, I agree with Jochem. If you periodicaly solve issues, such this - you must know about behind assertions in pcre. I ask google, and google give me good manual. http://www.pcre.org/pcre.txt open this page and use brouser search interface to find section PCREPATTERN or PCRE REGULAR EXPRESSION DETAILS it is best manual about PCRE (IMHO) But I don't know - is php pcre fully compatible with pcre library.

[PHP] Match anything between two " that is not a " except if it is escaped...
Hi everyone,
I am struggling with regular expression trying to match strings
delimited by double quotes, but taking into consideration that \" is not
a string ending character.
---8<---
-
$in = 'this is a string : "Hi everyone my name is \"Mathieu\"!" Here is
a second string : "PHP is just perfect"';
// pattern for catching strings between "
$pattern = '#"([^"]*)"#';
// surround matching string with HTML span code to highlight
$replacement = '"${1}"';
// perform the reg exp replacement
$out = preg_replace($pattern, $replacement, $in);
---8<---
-
$out contains :
this is a string : "Hi everyone my name is \"Mathieu\"!"
Here is a second string : "PHP is just perfect"
This behaviour is normal considering my pattern (anything between two "
that is not a ").
But I don't know how to get this :
this is a string : "Hi everyone my name is \"Mathieu\"!" Here is
a second string : "PHP is just perfect"
I would like my pattern to express : Anything between two " that is not
a " except if it is escaped.
Thanks for reading me, any help in return is welcome !
