Question

How can I convert from bytes to float in php? Like in Java

int i = (byte3 & 0xff) << 24 | (byte2 & 0xff) << 16 | (byte1 & 0xff) << 8 | byte0 & 0xff; 
Float.intBitsToFloat(i);

Answer 1

There may be a more direct way, but here you go:

<?php
var_dump(unpack('f', pack('i', 1059760811)));
?>

This is, of course, machine dependent, but I don’t know of any machine running PHP that doesn’t use IEEE 754 floats.
