Get [KEY] value of array?

[condoug]

Hi

Is there a way to find out what the KEY of an array is by using the array VALUE as the search criteria?

E.g. I have the following array:

Array
(
    [0] => 1
    [1] => 'two'
    [2] => 3
    [3] => 4
    [4] => 'not 5'
    [5] => 6
    [6] => 7
    [7] => 'another test'
    [8] => 9
    [9] => 'test example'
    [10] => 11
    [11] => 12
    [12] => 13
    [13] => 14
    [14] => 15
    [15] => 16
    [16] => 17
    [17] => 'blah blah'
    [18] => 19
    [19] => 20
    [20] => 21
}

So while I am looping through the array above, I am looking for the key where the value matches 'blah blah'.

Thanks for reading.
