Hello, Do you know the answer to this got'tcha? I want to call usort with a variable function name. Basically, I want usort to sort any field I specify. Currently, I'm stuck declaring a pile of functions and calling usort from if/elseif statements. :-(
Current: function compname ($a, $b) { return strcmp ($a["name"], $b["name"]); } function comptitle ($a, $b) { return strcmp ($a["title"], $b["title"]); } function compcity ($a, $b) { return strcmp ($a["city"], $b["city"]); } function compdesc ($a, $b) { return strcmp ($a["description"], $b["description"]); } function compfile ($a, $b) { return strcmp ($a["filename"], $b["filename"]); } if ($sortby == "name") { usort ($result, "compname"); } elseif ($sortby == "title") { usort ($result, "comptitle"); } elseif ($sortby == "city") { usort ($result, "compcity"); } elseif ($sortby == "description") { usort ($result, "compdesc"); } elseif ($sortby == "filename") { usort ($result, "compfile"); } What Works in Theory: function mysort ($a, $b, $c) { return strcmp ($a["$c"], $b["$c"]); } usort ($result, "$mysort, $sortby"); ...but, that chokes. Your help appreciated. :-) Rob ---------------------------------------------------------------------- Robert J. Miller Internet Support Specialist Department of Government Services and Lands P.O.
