Das Sortieren von Werten oder Schl\u00fcsseln eines Hashes ist oft notwendig. Hier gehen wir einige Varianten der Sortierung anhand eines Hashes %EP beispielhaft durch.<\/p>\n

Hash nach Werten aufsteigend sortieren:
\nforeach $tm (sort { $EP{$a} <=> $EP{$b} } keys %EP) {
\nprint $tm .“=“. $EP{$tm} .“\\n“;<\/span><\/p>\n

Hash nach Werten absteigend sortieren:
\n( sort { $EP{$b} <=> $EP{$a} } keys %EP )<\/span><\/p>\n

Hash nach L\u00e4nge der Schl\u00fcssel absteigend sortieren:
\n( sort { length($b) <=> length($a) } keys %EP )<\/span><\/p>\n

Hash nach L\u00e4nge der Werten aufsteigend sortieren:
\n( sort { length($EP{$a}) <=> length($EP{$b}) } keys %EP )<\/span><\/p>\n

mehrdimensionalen Hash zum Beispiel nach zweitem Element aufsteigend sortieren:
\nsort { $EP{$a}->[1] <=> $EP{$b}->[1] } <\/span><\/p>\n
