PHP variable organization

[bentro]

When you make long pages of php that you are using multi variables in, I recommend declaring the variables at the top of the page like this

<?php
if(isset($_POST["var1"])){$var1==$_POST["var1"]}

//Content

?>

this makes the coding less confusing and easier to read

I do that frequently, except I prefer to use !empty to check my variables. A variable can remain set even if has a NULL value.
