Problem reading binary file

[Browzer]

Hello, first poster here. 

 

I have to read bytes from a binary file.  Often, I'm only reading 1 or 2 bytes at a time.  The problem is that what I'm reading is being displayed as garbage.  For example:

 

$fh = fopen($filepath, 'rb') or exit("Can't open file");		
$byte =  fread($fh, 2) or exit("Can't read file");
printf("Byte = %u", $byte);

 

The output is "Version = 0" (if I treat $byte as a string, the output is "Bytes = ?").  That is not correct.  Here is the equivelant Java code reading from the same file:

 

File f = new File(filepath);
FileInputStream fis = new FileInputStream(f);
DataInputStream dis = new DataInputStream(fis); 
short version = dis.readShort();
System.out.println("Version = " + version);

 

The output is "Version = 2", which is correct.

 

Any ideas?  Thanks.

Why are you using printf()? Try using echo instead:

 

<?php

$fh = fopen($filepath, 'rb') or exit("Can't open file");		
$byte =  fread($fh, 2) or exit("Can't read file");
echo "Byte = ".$byte;

?>

 

 

Orio.
