Ich dachte, er will zuerst Großbuchstaben. Du meinst, er will: ~~~php <?php $final_array[0]['score']='bar'; $final_array[1]['score']='Foo'; $final_array[2]['score']='Bar'; $final_array[3]['score']='foo'; usort( $final_array, function( $a, $b ) { echo '"' . $a['score'] . '" <=> "' . $b['score'] . '" : ' . ( $a['score'] <=> $b['score'] ) . ' => ' . ( -1 * ( $a['score'] <=> $b['score'] ) ) . PHP_EOL; return -1 * ( $a['score'] <=> $b['score'] ); } ); print_r( $final_array ); ~~~ mit diesem Ergebnis? ~~~ "bar" <=> "Foo" : 1 => -1 "Foo" <=> "Bar" : 1 => -1 "Bar" <=> "foo" : -1 => 1 "Foo" <=> "foo" : -1 => 1 "bar" <=> "foo" : -1 => 1 Array ( [0] => Array ( [score] => foo ) [1] => Array ( [score] => bar ) [2] => Array ( [score] => Foo ) [3] => Array ( [score] => Bar ) ) ~~~
