usort numerically

[leena]

Hi everyone,

I am trying to sort an array.

I am using usort, and it seems to work most of the time whether I am sorting by an alpha numeric string, or just a number.

For some reason though once in a while it will sort a number like you would a word...
So now instead of it being sorted:
114
90
10
6

It will just sort by the first number, so it will look like this:
90
6
114
10

Why is this happening? and how can I get it to distinguish between a letter and a number?

Thanks for your time. Any help is greatly appreciated.

That only happens when PHP interprets the variant as a subtype of CHAR or STRING instead of INT. Make sure that you use trim() the values before putting them into the array.
