Check a variable after call it PHP

[Maseonary]

I have a varaible:\[code\]$this->valuepicname = isset($_POST['picname'][$numberpicname]) ? $_POST['picname'][$numberpicname] : "";\[/code\]The varabile $numberpicname is static and each time I call to - it has another value, so, I want to do it too with th varaible $valuepicname - but I can't define it as static ($valuepicname) because its IF statement (i think this is the reason..).Hope you understand.. (my english is bad)Thank you.
