preg_match binary strings??

[Anon]

I'm trying to parse out a binary file. i opened the file okay, and got the entire contents into the string - verified. now, the problem is, that i'm trying to search for a binary string in the huge binary string. preg_match won't spit back any binary data!

i'm trying to cilp the huge string to everything before the binary pattern saved in $clip - yes i'm new to php 🙂

#the search patter i ned
$clip = chr(82) . chr(83) . chr(00) . chr(00);

#right function to call?
$clip = addslashes($clip);

#$data has the huge binary string
if(preg_match("/(.+)$clip/s", $data, $regs)){
$data = $regs[1];
echo $data;
}

what's goin on? i'm positive $clip is in $data, but preg_match won't return binary data.

thanks in advance

I don't know anything about preg_match but I can figure this part out, Addslashes doesn't do what you need it to do. Addshalshes is used to put slashes before a quotation mark for compatibility not to add slashes to a perl expression.

I'm guessing that you wish to put slashes on either the ends (begining and end) of the $clip values or in between each char.

So for the ends just do this.

$clip = "/".chr(82) . chr(83) . chr(00) . chr(00)."/";

Or if it's between each value the the easiest way would be to create an array and implode() it.

$array[] = chr(82);
$array[] = chr(83);
$array[] = chr(00);
$array[] = chr(00);

$clip = implode("/",$array)

I guess the thing to remember is that php doesn't really destingush between a text file and a binary file, it leave that part up to you.
