Hi all, I've a problem thats been bothering me for a week now I have an array $animals keys and values like this 1 => cat 2 => dog 3 => mouse 4 => horse I want to be able to access them using either a key or a pointer, however the key/pointer will be a variable without variables, if I want dog, I can either use $animals[1] or $animals['2'] but with a variable , eg. $x = 2 $animals[$x] will always give me 'mouse' what syntax do I need to use for $animals[$x] to give me 'dog' when $x=2 ?

I would think that you have string keys instead of integer ones. Perhaps there is some whitespace in the variable using to set the key? For example: $array = array(' 2' => 'dog'); // there is a whitespace before the number 2 will set the element of ordinal number 0 and key ' 2' to 'dog'. To get that value you would either ask for $array[0] or $array[' 2']. Doing a print_r() or var_dump() on the array will let you know what the actual contents of both the keys and values are. Satyam
