How to convert array/string to integer?

    only like this:
    $int = array[0] + (array[1] << 8) + (array[2] << 16) + (array[3] << 24);
    ?

    I can't use type casting because it will make a '1111'(4-bytes array) string into 1111(2-byte int), and it's not what i want.

    If mask is a int variable, mask.bin if a file with only 4-byte, so:
    $mask = file_get_contents('mask.bin');
    will make $mask a string not a int???

    Are PHP string variable a pointer to first char in the array? I come from C++...

    Thanks

    Well, you can try the following:

    
$mask = file_get_contents('mask.bin');
$int = intval($mask);
