as self defined sorting function

private function arraysort($a, $b) { if ($a == $b) { homecoming 0; } homecoming ($a < $b) ? -1 : 1; }

when phone call sort function above dataset , function using uasort($arraytosort,array('self','arraysort)); info in exact same order. have tried using comparing functon usort, , values sorted (albeit without keys of course). life of me cannot see why uasort failing sort these values when usort capable of doing so. calling function incorrectly?

your phone call uasort seems wrong compared code provided.

if want phone call uasort using standalone callback, should utilize uasort($array, 'arraysort');

if want phone call uasort within object instance, while callback instance method, should utilize uasort($array, array($this, 'arraysort')); (cause method private assume phone call need)

if want phone call uasort within object instance, while callback static method of current class, then should utilize uasort($arraytosort,array('self','arraysort'));

additionally can simplify sort method this:

private function arraysort($a, $b) { homecoming strcmp($a, $b); }

according answer, , assuming examples listed above "strings", need split values first, before sorting access actuall integer @ end of string.

using uasort($array, array($this, 'arraysort')) in class, along

private function arraysort($a, $b) { $intofa = explode(":", $a); $intofa = intval(trim($intofa[1])); $intofb = explode(":", $b); $intofb = intval(trim($intofb[1])); homecoming $intofa - $intofb; }

should trick.
