Deprecated: Function create_function() is deprecated
$compare = create_function('$a, $b', $code);
Iemand die wil aangeven hoe deze regel herschreven kan worden zodat 7.2 het ook akkoord vindt?
Alvast dank!

If you are using PHP 5.3.0 or newer a native [url=https://www.php.net/manual/en/functions.anonymous.php[/url] anonymous function should be used instead.

$compare = function($a,$b){
return eval($code);
}
return eval($code);
}
Maar beter is het om de $code gewoon uit te schrijven (als dat kan; als het het niets "magisch" is wat weer uit een database, of andere hoek van je programma komt). Dus stel dat:
Code (php)

$code = '$a <=> $b';
//dan wordt:
$compare = function($a,$b){
return $a <=> $b;
}
//dan wordt:
$compare = function($a,$b){
return $a <=> $b;
}
NB. de bouwer van deze module is niet-bereikbaar en ik 'spreek' te weinig PHP om dit op te lossen. Vandaar de vraag.

Garantie tot de deur. Ik kreeg in ieder geval geen parse errors (ship it!), maar ik had geen data om mee te testen.

Die had ik gelezen, maar lukt me nog niet deze te vertalen naar een oplossing van de foutmelding.Dit al gelezen?

DDank je Rob. Deze leidt alleen tot een foutmelding
