Sizing up an array?

[Anon]

Hi, can anybody tell me how I can get the size of an array, it will be used in connection with the previous thread below - titled 'Validate This'!

Here is what I have so far...

if (empty($name)) {$missing = array('Name');}

if (empty($email)) {$missing = array('Email');}

if (empty($age)) {$missing = array('Age');}

Following the example in my previos thread...
This to my understanding would build an array with the following elements in the array 'Email' & 'Age';

But because I don't know what fields they left I can not assign a key, and thus do not know how to find out how many elements reside within the array!

Once I know how many elements are in the array I can then use something like...

while ($array_key <= $array_size) { print "Value missing for " . current($missing);}

If I am -dare I say- missing something, please correct my syntax and post it here.

Thnx,
Charlie

Try:
sizeof($missing)

Then you'll be able to do something like this:

if (sizeof($missing) > 0) {
print("You need to input: ");
for(reset($missing);
$index = key($missing);
$value = next($missing))
{
print("$index ");
}
print("<BR>\n);
// form with missing elements here
}
