PHP how to loop through a post array

phppost

I need to loop through a post array and sumbit it.

#stuff 1
<input type="text" id="stuff" name="stuff[]" />
<input type="text" id="more_stuff" name="more_stuff[]" />
#stuff 2
<input type="text" id="stuff" name="stuff[]" />
<input type="text" id="more_stuff" name="more_stuff[]" />

But I don't know where to start.

Best Solution

This is how you would do it:

foreach( $_POST as $stuff ) {
    if( is_array( $stuff ) ) {
        foreach( $stuff as $thing ) {
            echo $thing;
        }
    } else {
        echo $stuff;
    }
}

This looks after both variables and arrays passed in $_POST.
