How to test every element of an array

[jrwap]

I have an array of numbers and I have another number which I want to test to see if it is in the array. How do I do this?

So, if I have the numbers 4, 5, and 6 in the array called $list and I have a variable called $test which contains the number 5. How do I test the contents of the variable against every item in the array.

Thanks ... ummm probably to my hero MAX!!

bool in_array ( mixed needle, array haystack [, bool strict])

PHP Docs: in_array()

How's that for service?

A+ service once again. I'll give it a try in a bit.

Thanks again,

You might want to note that in_array() returns a boolean value. If you want the key where the element was found, you'll need to use array_search().
