Need help sorting an array

[djeyewater]

I have an array that contains values like _img_1.png, _img_2.png, _img_3.png, Back.png. How can I sort them so that they appear in this order? I've tried sort() and natsort() but Back.png is always appearing at the start of the array.

its because of the underscore in front of the image names. PHP counts that in sorting.

make a temporary array... loop through the array and make another array with all items that dont begin with an underscore.... either remove those items from the initial array or make a new array with just underscored items.

Sort both the arrays independantly. Treat the array with underscores as 'first' and the other last.

Thanks for the replies, I thought that an underscore would come before a letter. Is there a list anywhere of how php prioritises characters when performing a sort?

is how php distinguishes values of characters.
