Title
Body
I have an array where I want to search the uid and get the key of the array. Examples Assume we have the following 2-dimensional array: $userdb = array( array( 'uid' => '100', 'name' => 'Sandra Shush', 'pic_square' => 'urlof100' ), array( 'uid' => '5465', 'name' => 'Stefanie Mcmohn', 'pic_square' => 'urlof100' ), array( 'uid' => '40489', 'name' => 'Michael', 'pic_square' => 'urlof40489' ) ); The function call search_by_uid(100) (uid of first user) should return 0 . The function call search_by_uid(40489) should return 2 . I tried making loops, but I want a faster executing code.
