[PHP] Array query - finding the key for a value
This may be a silly question, but I'm used to being able to find PHP functions to do whatever I want, but I can't find one to do this! If I have an array like this: [0] - 'apple'; [1] - 'pear'; [2] - 'orange'; [3] - 'apricot'; I know I can use in_array() to check whether, say, 'orange' is in the array; but how do I then find out which index 'orange' is at? -- Tim Fountain ([EMAIL PROTECTED]) http://www.tfountain.co.uk/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
