※ Download: Php sort array by key value
However, if you use code analyzers or a compile cache, things can be very different. Both execution time and memory usage are very low.
Note: Other sorting functions include asort , arsort , ksort , krsort and rsort. Pardon the shameless self promotion ;.
Sorting Arrays - We can use a few different methods to do this.
How can I sort my array by values, while maintaining keys? I wear a lot of hats - Developer, Database Administrator, Help Desk, etc. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform. I hope this helps with your problem. This is first creating a new array, with a single element who's key is 'a' and value is 'Apple'. My apologies, I'm struggling to explain it however hopefully it makes some sense to you. Cheers Matt It's more than this solution.

One of the tasks that less experienced programmers find really difficult is to sort multidimensional arrays by one of the values in the child arrays. Using this method we can sort the multi-dimension array depending on values of multiple different keys. This is first creating a new array, with a single element who's key is 'a' and value is 'Apple'. You can view the demo of all these methods. Again, while using a bit more memory, the temporary array path seems to be the way to go. Use this function to retrieve all the values from an associative array. The bubble sort method has already failed whereas method 3 in which we assign the sorting column as the key of a temporary array seems the fastest but uses the most memory. Stabilizing the sort functions in this case, usort.
