$post_array = array("title","content","price","dt","cat");

i want to make variable for all of them like this :

You can do simply using extract.

extract($_GET);

See doc.

If you want to make sure all of them exist, you can use a for loop this way:

foreach($post_array as $input) {
    $$input = $_GET[$input];
}

This works because in php if say $var is 'title', $$var refers to the variable $title.
