Return the number of files in a directory with PHP

Posted in Daily on Aug 24th, 2007

A code snippet that returns the number of files in a directory. Useful for looping slideshows where the images are uploaded by other people.

<?PHP
header("content-type: text/plain\n\n");
clearstatcache();
$search = "your directory here"; //replace with the target directory, without ending slash
$dir = @opendir("$search");
$i=0;
$j=0;
while(($file = readdir($dir)) !== false) {
     if(is_dir ($search . "/" . $file)) { $i++; }
       else { $j++; }
     }
closedir($dir);
echo "Number of files: ".$i;
?>
 

I used this as a LoadVars() in Flash so it would return me a number for my loop limit.

Just replace this:

echo "Number of files: ".$i;
 

with:

echo "&imageNum=".$i;
 

And then for the LoadVars in Actionscript…

var my_lv = new LoadVars();
my_lv.onLoad = function(success){
    if(success){
       numOfImages = this.imageNum;
       trace(numOfImages);
     }
};

my_lv.load("url of the php file above");
 

Sorry for the programmer talk, I am still a BiMbO!~~!~
