PHP natsort() Function
 Complete PHP Array Reference
Definition and Usage
The natsort() function sorts an array by using a "natural order" algorithm. The values
keep their original keys.
In a natural algorithm, the number 2 is less than the number 10. In computer
sorting, 10 is less than 2, because the first number in "10" is less than 2.
This function returns TRUE on success, or FALSE on
failure.

Example
<?php
$temp_files = array("temp15.txt","temp10.txt",
"temp1.txt","temp22.txt","temp2.txt");

echo "Standard sorting: ";
print_r($temp_files);
echo "<br />";
natsort($temp_files);
echo "Natural order: ";
print_r($temp_files);
?>

The output of the code above will be:
Standard sorting: Array
(
[0] => temp1.txt
[1] => temp10.txt
[2] => temp15.txt
[3] => temp2.txt
[4] => temp22.txt
