"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).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.PHP 5.3 will transfer reference into value (when $values Array is destroyed) and you will get "Parameter 1 to array_multisort() expected to be a reference, value given" warning again otherwise.Final code should look like this: I was (as near everyone here :-) looking to sort 2-dimensional arrays by certain fields in the associative sub-arrays.So all sorting arrays have to be collected into new one as a references to array variables: This (requiring arguments to be a reference) is not actually a problem since source array will not be sorted otherwise. Don't forget to destroy $values Array variable if you use it over each array_multisort() argument processing iteration.If you don't do it, all array_multisort() arguments will contain the same array: And the last important thing :)Collect sorting arrays somewhere.
In this example, after sorting, the first array will transform to "10", 100, 100, 11, "a" (it was sorted as strings in ascending order).
In my case, the indexes were IDs and the values were a percentage of how relevant the object was, considering an earlier query.e.g: $search Result = (23 = 0.9); I wanted to use array_multisort to first sort DESC on the IDs, and then on the values DESC. I wanted to show the highest values first, but in case of two (or more) objects with the same value, the higher ID would be shown first.e.g: $search Result = (10 = When sorting an array of (complex) objects, this function can give you a "Fatal error: Nesting level too deep" since it directly compares elements in later arrays if the elements in earlier ones compare equal.
This can be worked around with the Flag-Parameter: I'm replacing an 'uasort()'-call which is significantly slower since it leads to a lot of calls to the comparison-function but most of the objects involved are recursive.
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.This function passes the entire child element even if it is not a string.
