Undefined index: string in (...) <p>I need to switch on E_ALL and get the in the title mentioned warning, when I am exploding the $_GET string: </p> <pre><code>$input = explode( '/', $_GET['string'] ); </code></pre> <p>Where does that come from? Is it the missing 3rd parameter (limit) for explode ? I want all entries.</p> <p>Cheers</p>
