9 ways of sorting plus 2

Posted by admin (Graham Ellis), 3 January 2005
There are at least 11 different sorting functions built into PHP!
-Regular ArrayBy Key (Associative Array)By Value(Associative Array)
Regular sortsortksortasort
Reverse sortrsortkrsortarsort
User sortusortuksortuasort

If you're sorting a regular array, choose a function from the first column; if you're sorting an associate away, the choose the second or third column depending on whether you want to sort by the array's keys or values.

The sorts listed in the first row will provide forward or reverse sorts based on the numeric or ASCII values of the values to be sorted; if you need somethine else, use the functions in the last row, each of which requires an extra parameter - the name of a function that you provide to put two elements in the right order.

You can also use natsort and natcasesort instead of the regular sort function if you want to sort strings in their natural (dictionary) order rather than in ASCII order.
