How to get the number of jpeg files on a folder ?

How can one find out in PHP the number of jpeg  files in a folder ?

 

 

Thanks

Use opendir() to get the handle of the directory then use a while with readdir() to get each filename. Check to see if the filename has the jpg extension then increment a counter.

Just use something along the lines of:

 

<?php
$path = "./images/";
$dh = opendir($path);
$NumOfFiles = 0;
while ($file = readdir($dh))
{
  if(eregi("(.*\.jpg)",$file))
  {
    $NumOfFiles++;
  }
}
closedir($dh);
echo $NumOfFiles;
?>

 

It's untested but it should work, if my memory serves haven't done php in a while.

There's also the glob() function
