I have an array with values $somearray = array(‘car’,’bike’,’legs,’car’). I’d like to find out which of these values in $somearray are repeated and pick out the index. In this example the answer would be ‘car’ and the index of the array would be 0 and 3.
I’m wondering if this can be done simply in a few lines, perhaps using some PHP function that I don’t know, or do I need to explicitly make comparison in nested loops?
TIA!
The solution is pretty simple and I bet you can write it yourself. All you need is just 2 functions: array_count_values() and array_keys() with specified second argument (thanks to @prodigitalson)
