XML Parsing Error: syntax error NULL ^

What is that mean? I'm a beginner.

I want to export videos, thumbs, duration, etc from my website into a xml format. I got this error: Invalid argument supplied for foreach() $output .= ' <clips>'; if (!is_array( $vids )) { $vids = array( ); foreach ($imgs as $img) { $img = explode( '.', $img ); $vids[] = '0' . $img[0] . '.flv'; } } @sort( $vids ); @sort( $imgs ); $i = 38; foreach ($vids as $v) { $output .= ' <clip>'; $output .= ' <duration>' . $duration . '</duration>'; $output .= ' <width>' . $width . '</width>'; $output .= ' <height>' . $height . '</height>'; $output .= ' <flv>' . $v . '</flv>'; $output .= ' <screens> <screen>' . trim( $imgs[$i] ) . '</screen> </screens>'; $output .= ' </clip>'; ++$i; } $output .= ' </clips>'; Thank you!
