PHP directory listing

Many times we have to display the list of files in a directory. We can keep the script in any location and by using the file path we can display the files inside the directory. Read the path and the script will take care to list the files inside that. Here is the code.

// open the current directory by opendir
$handle=opendir(".");

while (($file = readdir($handle))!==false) {
echo "$file <br>";
}

closedir($handle);

Reading and displaying all images present inside a directory

We can use the same code to read all the files in a directory and assuming that all are images, we can display them. Here is the code to do this.

$path='images/';// change the path here related to this page
$handle=opendir($path);

while (($file = readdir($handle))!==false) {
if(strlen($file)>3){echo "<img src=$path$file> <br>";}
}
closedir($handle);

You can also list the files and directories by using dir function scandir()
