Wie kann ich doppelte Werte aus einem mehrdimensionalen Array in PHP entfernen?
Beispiel-Array:
Array
(
[0] => Array
(
[0] => abc
[1] => def
)
[1] => Array
(
[0] => ghi
[1] => jkl
)
[2] => Array
(
[0] => mno
[1] => pql
)
[3] => Array
(
[0] => abc
[1] => def
)
[4] => Array
(
[0] => ghi
[1] => jkl
)
[5] => Array
(
[0] => mno
[1] => pql
)
)
