Is it ok to use strlen over empty() ?

[bugzy]

Just a beginner question guys.

 

Since empty() is treating number 0 as NULL I wonder if this is an okey alternative so 0 is going to be accepted..

 

 

     

 

<?php $is_num = strlen(trim($item_stock));

if($is_num < 1)
{
	//is empty
}
else
{
	//has a value
}

?>

You could just do if ($is_num !== "")

Thanks scootah.. but you think using strlen will be fine also?

It will probably work, but it's not the best solution.
