I have a directory of images, called "random". In it are the following
files:
1.gif
2.gif
3.gif
4.gif
I use this script to choose a random image and display it:
$i = -2; // $i = -2 so that the directory files ("." and "..") won't be
counted.
if ( $dh = opendir( "images/random" ) ) {
while ( false !== ( $file = readdir( $dh ) ) ) {
$i++;
}
closedir( $dh );
$rand = rand( 1, $i );
$randimg = '<img src="images/random/' . $rand . '.gif" />';
}
print $randimg;
This works just dandy. However, I figure there must be a more efficient way
to count the number of files in a directory. Is there a directory's
equivalent of a function like file()? Or is my script the only way to count
the files?
Thanks.
