So, using the above data, we can perform this sort instead: array_multisort works normally in php 5.3, but it forces arguments to be references.It doesn't make differences for common array_multisort() usage, but makes "problems" for sorting variable number of arrays where call_user_func_array() function is involved.It has to be declared global and set somewhere outside of compare().Often, one may have a group of arrays which have parallel data that need to be kept associated with each other (e.g., the various attribute values of a group of elements might be stored in their own arrays).The second will contain 1, 3, "2", 2, 1 (sorted as numbers, in descending order).I came up with an easy way to sort database-style results.I was tricked by this message because of couse I wanted to have the *sorted* array back.

If you would like to enable call-time pass-by-reference, you can set allow_call_time_pass_reference to true in your INI file..a line like this:array_multisort (&$keyarr, &$arr );// sort against this keys This message is not easily switched off by changing the error reporting level because it's produced at parsinig time -- not execution time.

"This could be misunderstood cause a sort as numbers in descending order will be 1, 1, "2", 2, 3.

My proposal is as follows (in a best english should be great ^^) :"In this example, [...] The second will contain 1, 3, "2", 2, 1 (sorted as well as first one, except for values 3 and "2" sorted as numbers, in descending order).

This function passes the entire child element even if it is not a string.

If it is an array, as would be the case in multidimensional arrays, it will pass the whole child array as one parameter.
