PHP Convert a big binary file to a readable file

Looks like your file path is missing a backslash, which could be causing file_load_contents() to fail loading the file.

Try this instead:

$file = "C:\\\\Users\\Alejandro\\Desktop\\integers\\integers";

EDIT: Now that you can read your file, we're finding that because your file is so large, it's exceeding your memory limit and causing your script to crash.

Try buffering one piece at a time instead, so as not to exceed memory limits. Here's a script that will read binary data, one 4-byte number at a time, which you can then process to suit your needs.

By buffering only one piece at a time, you allow PHP to use only 4 bytes at a time to store the file's contents (while it processes each piece), instead of storing the entire contents in a huge buffer and causing an overflow error.

Here you go:

$file = "C:\\\\Users\\Alejandro\\Desktop\\integers\\integers";

// Open the file to read binary data
$handle = @fopen($file, "rb"); 
if ($handle) { 
   while (!feof($handle)) { 
       // Read a 4-byte number
       $bin = fgets($handle, 4);
       // Process it
       processNumber($bin); 
   } 
   fclose($handle); 
}

function processNumber($bin) {
    // Print the decimal equivalent of the number
    print(bindec($bin)); 
}
