Reading a File into a Byte Array (PHP)

Question

I have one file. but now need to read this file into a bytes array. In java or c++ it\'s very easy to do that. but not found how i can read in PHP.

Answer 1

You can read the file into a string like this:

$data = file_get_contents("/tmp/some_file.txt");

You can get at the individual bytes similar to how you would in C:

for($i = 0; $i < strlen($data); ++$i) {
    $char = $data[$i];
    echo "Byte $i: $char\n";
}
