Turn binary number 0xFFFFFFEE into a float?

[JimmyR.com]

I have a binary file which only has 4 bytes "FFFFFFEE". I just want to
put it in a variable equaling 4294967278.
How I've failed so far:

<?

$foo= bin2hex(file_get_contents('testplz.bin'));

// This correctly creates the hex number but on closer inspection it
just turned it into a string.

$foo=intval(bin2hex(file_get_contents('testplz.bin ')),16);

// This works up until the value exceeds 2147483647, there's a
function called floatval but it doesn't accept the ,16 argument and
doesn't accept binary either

settype($foo, "float");

// Any variation of bin2hex, casting, etc don't seem to give me a
correct answer

echo (float)bin2hex(file_get_contents('testplz.bin'));

?>
Please help ='/, I can't proceed with what I need to finish.

$foo= hexdec(file_get_contents('testplz.bin')); should do the trick.

Bye!

it returns 0

Thanks for all the detail but the first thing I said was its a binary
file. It's not FFFFFFEE ASCII. Someone else helped me figure it out
though, here's a function I made

function b2f($val) return floatval(hexdec(bin2hex($val)));

echo b2f(file_get_contents('testplz.bin'));
