*/
function searchdir($basedir)
{
global $filelisting, $number; //defines the two variables as global so they can be accessed from outside the function
unset($filelisting); //kills $filelisting in case it have been used earlier in the script
unset($number); //same as above
$handle=opendir($basedir);
while ($file = readdir($handle)) {
if ($file=="." or $file=="..") {
}
else {
$filelisting[]="$basedir$file";
};
};
$number=sizeof($filelisting); //gets the size of the array
};
searchdir("./"); //runs the function to search the current directory
echo $filelisting[1]; //echos the second value in the array
echo $number; //echos the size of the array
