Binary File

[monarlte]

Hi.

 

I am wanting to write a php script that will output the binary value of a binary file.  When I print the current chunk, I just get the following printed to the screen: "Resource id #3".  And when I load the whole file contents into a string variable and then print that string, I just get jibberish printed to the screen.  Could somebody please tell me how I could print the binary value of the file?  Thank you.

 

$filename = 'song.mp3';

 

if (file_exists($filename)){

 

  //This will print jibberish

  $handle = fopen($filename, "r");

  $contents = fread($handle, $filesize);

  fclose($handle);

  print $contents;

 

  print '<br /><br />';

 

  //This next part will print "Resource id #3"

  $handle = fopen($filename, "r");

 

  while(!feof($handle)) {

    $chunk = fread($handle, 1024);

    print $handle;

    print '<br /><br />';

  }

 

}

the.. binary file value.. is SUPPOSED to be "jibberish"?

 

btw file_get_contents($filename) is simpler

I want to print the bits of the file (the 1s and 0s), how can I do that?

Once you get the contents into a string, do something like the following:

<?php
$str = 'sdfasi0sdjfa09c8hds8cusd8uas8';
for ($i=0;$i<strlen($str);$i++)
printf("%08b ",ord($str[$i]));
?>

thanks Ken.  How could I now display the binary as ASCII text characters?

 

thanks so much.

What this is doing is creating binary out of the ASCII characters, Its taking the "jibberish" and converting it to binary (lol, jibberish still, huh), converting it back to ASCII would be redundant and would thus render the initial conversion uneeded.

i'm not sure i understand but you may want to look into system() if you're trying to compile binary data.
