chars in an array

[Anon]

I use a POST form to collect data. I would like to check how many chars are passed.

With GET method I just check a string $QUERY_STRING length.

But with POST method I get an array $HTTP_POST_VARS.
Is there a special function to check how many chars are in an array?

Is there a simplier method to check how many chars are passed with POST form?

Thanks,

Let's assume you have an entry like:

$HTTP_POST_VARS["last_name"];

You can find the length of that variable by using strlen:

print strlen($HTTP_POST_VARS["last_name"]);
