I was tricked by this message because of couse I wanted to have the *sorted* array back.
And couldn't find the ini file nor the declaration of array_multisort.
This does what example 3 does, except it takes care of creating those intermediate arrays for you before passing control on to array_multisort().
Hi, I would like to see the next code snippet to be added to Purpose: Sort a 2-dimensional array on some key(s)Advantage of function: - uses PHP's array_multisort function for sorting;- it prepares the arrays (needed by array_multisort) for you;- allows the sort criteria be passed as a separate array (It is possible to use sort order and flags.); - easy to set/overwrite the way strings are sorted (case insensitive instead of case sensitive, which is PHP's default way of sorting);- performs excellent function Multi Sort($data, $sort Criteria, $case In Sensitive = true) Usage://Fill an array with random test datadefine('MAX_ITEMS', 15);define('MAX_VAL', 20);for($i=0; $i USort function can be used to sort multidimensional arrays with almost no work whatsoever by using the individual values within the custom sort function.
If it is an array, as would be the case in multidimensional arrays, it will pass the whole child array as one parameter., $array) ///____________________// array Column Sort() / I would like to report a kind of confusion that arose with the message Warning: Call-time pass-by-reference has been deprecated; If you would like to pass it by reference, modify the declaration of array_multisort().If you would like to enable call-time pass-by-reference, you can set allow_call_time_pass_reference to true in your INI file..a line like this:array_multisort (&$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.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.
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.
