[SOLVED] View Binary of a file in PHP

[Daleeburg]

So I got this whack job idea that I would like to build a zip program.  Not that I expect it to go anywhere, just use it as a personal learning experience and work on my PHP skills.

 

I really like PHP and like to use it as a prototyping language because of how easy it is to work with, but I have run across one question that I have not been able to find an answer for.

 

Is it possible to read the binary of a file?

 

Everything on a computer is 1s and 0s, so in PHP is it possible to read all the 1s and 0s of a file and have them come out as a 1s and 0s string?

 

Thanks for any help head of time.

$fileData = file_get_contents($fileName);
$fileLength = strlen($fileData);
for ($i = 0; $i < $fileLength; $i++) {
   $binary = decbin(ord($fileData{$i}));
   echo $binary.'<br />';
}

You sir are good.

 

Thanks

Also look at dechex()... hex values are a lot easier to read than binary
