Converting a PHP anonymous function to non-anonymous

[RobJacko]

I asked a related question before I lost my login id - http://stackoverflow.com/questions/...-syntax-error-unexpected-t-function-expecting - but this is the "entire" problem.I'm having a hard time figuring out how to convert this function (got from somewhere on SO) to work with PHP 5.2.14 (which as folks informed me - does not support anonymous functions). I tried a few permutations of changing the code to make it work with array_map() but I cant wrap my head around how everything works!The entire function is pasted below, but only the areas pointed out are the ones that PHP 5.2.14 complains about..\[code\]function convertGeneralAvailabilityTime($date,$from_timezone,$from_timebegin, $from_timeend, $to_timezone){$tz1 = new DateTimezone($from_timezone);$datetime1 = new DateTime("$date $from_timebegin", $tz1);$datetime2 = new DateTime("$date $from_timeend", $tz1);$convertedAvail = array( array($datetime1, $datetime2),);$tz2 = new DateTimezone($to_timezone);//convert periods:// ISSUE_START$times = array_map( function (array $p) use ($tz2) { $res = array(); foreach ($p as $d) { $res[] = $d->setTimezone($tz2); } return $res; }, $convertedAvail);// ISSUE_END$res = array();foreach ($times as $t) { $t1 = reset($t); $t2 = next($t); if ($t1->format("d") == $t2->format("d")) { $res[$t1->format("l")][] = $t1->format("g:i a") . " to ". $t2->format("g:i a"); } else { $res[$t1->format("l")][] = $t1->format("g:i a") . " to 11:59 pm"; $res[$t2->format("l")][] = "12:00 am to ". $t2->format("g:i a"); }}return $res;}\[/code\]
