Getting Rid of Decimal Places in PHP

posted by james on November 25th, 2008

There’s a couple of ways to remove decimal places from a number in PHP…

$out = number_format($val,0);
$out = (int) @floor($val);

Interestingly, we ran a real-world test case of 10 million iterations of doing each of these, and it turns out that method #2 is approximately 0.5 seconds quicker. So there you have it, if you want to be 0.5 seconds quicker when removing decimal places from a number 10 million times.. then use the second method.
