Hi all,

I'd like to work with a binary file....

I read the whole file into variable (it conatains binary data from 00-FF):

$fp=fopen($cfg,"r");
$content=fread($fp,filesize($cfg));
fclose($fp);

// and then I'd like to check if it contains special binary sequence, let's say bytes "00 01
02 03":

$replacestring="/\x00\x01\x02\x03/im";

if (preg_match($replacestring,$content)==0) {
echo("bad input file format");
exit();
}

but i get error message:

<b>Warning</b>: preg_match(): No ending delimiter '/' found in <b>test.bat</b> on
line <b>57</b><br />

I think it is maybe because php uses strings terminated with null, but can i force php to
use strings with predefined length for example? Is there a way to work with strings
containing null characters?

Thank you in advance.

Y.
