... is_array function

[electricocean]

I am not really undertanding this. Can this check the keys or values or both?

I am looking at php.net and it doesn't say.

thanks.

is_array simply checks whether a variable is an array or not and returns true or false. It's nothing to do with keys or values.

[php.net...]

check the url.

see the examples.

i was wondering if that would be that way to go to see if a key was in an array, else do something else. But I guess not.

Naw, use array_key_exists() [php.net]
