Answer 1

Just add the slash in the character class and capture in group 1:

preg_match_all('@download.php/([^\s.,"\'/]+)@i', $sText, $aMatches);

The value you're looking after is in $aMatches[1][0]

Answer 2

You need to create a group by ( and )

preg_match_all ( '@download.php/([^/]+)@i', $sText, $aMatches );

print_r ( $aMatches[1][0] );
