Which PHP function to use to read a binary file into a string?

Answer 1

Try this

$handle = @fopen("/path/to/file.bin", "rb");
if ($handle) {
    while (!feof($handle)) {
        $buffer[] = fgets($handle, 400);
    }
    fclose($handle);
    $buffer[0][0] = chr(hexdec("FF")); // set the first byte to 0xFF
}
// convert array to string
