PHP Question

Sort array items in PHP so that it is not case sensitive to letters

When I use

I get something along the lines of:

  1. Apple

  2. Green

  3. Zebra

  4. grass

In this example, "grass" starts with a lower case g but ends up after "Zebra" which has a capital letter.

How do I make it so that it sorts it where it ignores whether the word starts with capitals or not?

  1. Apple

  2. Green

  3. grass

  4. Zebra

Call usort() as usort($topics, 'strnatcasecmp').

strcasecmp would do the job, too, but strnatcasecmp will also sort properly when you have numbers in your string.
