You have it backwords.. -333371788 is signed and the 3961595508 is unsigned. But... <?php $dec = -333371788; $unsigned = sprintf("%ul", $dec); print $unsigned; // == 3961595508 Do note that php doesn't have native unsigned numbers so doing something like this wont work right: printf("%d", $unsigned); // == 2147483647 So to convert it back you have to do something like: printf("%d", $unsigned+0); // == -333371788 Curt -- First, let me assure you that this is not one of those shady pyramid schemes you've been hearing about. No, sir. Our model is the trapezoid!
