Using filter to 'clean' $array

[stephan]

Hello,

Can someone please help me with this task?! I have read the documentation but haven't figuered out how to proceed with solving it. Here goes...

This array contains numerous entries that I am not interested in;

Array
(
[0] => TV3
[1] => TV3 Norge
[2] => PRO 7
[3] => 3+ Danmark
[4] => 3+ Danmark
[5] => TV3
[6] => TV3
[7] => PRO 7
[8] => 3+ Danmark
[9] => 3+ Danmark
)

I want to use this filter below to remove the unwanted entries from the array (i.e. entry 1, 2, 3, 4, 7, 8 and 9 in the array above);

Array
(
[0] => SVT1
[1] => SVT2
[2] => TV3
)

Hopefully I should manage to complete the next steps with this answer! 😃 Thank you very much!!!

I'd say the first order of business would be to run an [man]array_unique[/man]. From there, you'll just have to replace whatever values you want to change to the SVT's
