It's suposed to be strstr. This was an attempt to make sure that nobody could
get into any directories lower than the directory that contained the image
folders. Funny thing is it was still working with my typos. There probably is
a better way to do it, but by breaking it down is how I was able to understand
it. anyway I fixed it and It should look like this:
if(!is_dir($dirBase."/".$get_the_album) || strstr($get_the_album, ".") !=NULL
|| strstr($get_the_album, "/") !=NULL || strstr($get_the_album, "\\") !=NULL){
echo "Album does not exist.";

Later when I get home from work about 1, I am going to run your example so I
can see the differences.
