binary - PHP read file as an array of bytes -

i have file written using java program has array of integers written binary made loop on array , write using method

public static void writeint(outputstream out, int v) throws ioexception {     out.write((v >>> 24) & 0xff);     out.write((v >>> 16) & 0xff);     out.write((v >>> 8) & 0xff);     out.write((v >>> 0) & 0xff); } 

i'm ask how read file in php.

i believe code looking is:

$bytearray = unpack("n*",file_get_contents($filename)); 

update: working code supplied op

$filename = "myfile.sav";  $handle = fopen($filename, "rb");  $fsize = filesize($filename);  $contents = fread($handle, $fsize);  $bytearray = unpack("n*",$contents);  print_r($bytearray);  for($n = 0; $n < 16; $n++) {      echo $bytearray [$n].'<br/>';  }
