[PHP] Comparing files

2008-03-12 Thread mathieu leddet 
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!

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] Match anything between two that is not a except if it is escaped...

2008-01-17 Thread mathieu leddet 
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
$replacement = 'b${1}/b';

// perform the reg exp replacement
$out = preg_replace($pattern, $replacement, $in);

---8---
-

$out contains : 
this is a string : bHi everyone my name is \/bMathieu\b!/b
Here is a second string : bPHP is just perfect/b

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 : bHi everyone my name is \Mathieu\!/b Here is
a second string : bPHP is just perfect/b

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 !

 attend? don't understand what you mean BUT you have given the OP the
 answer by changing his regexp to include a [negative] look behind assertion
 for the backslash. :-)

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

Max, thanks for the link.

 PS - you solved the issue but did you learn what a [negative] look 
 behind assertion is?
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.
Also see documentation in php.net :)
