How To Read a Directory One Entry at a Time in PHP?

If you want to read a directory one entry at a time, you can use opendir() to open the specified directory to create a directory handle, then use readdir() to read the directory contents through the directory handle one entry at a time. readdir() returns the current entry located by the directory pointer and moves the pointer to the next entry. When end of directory is reached, readdir() returns Boolean false. Here is a PHP script example on how to use opendir() and readdir():

<?php
mkdir("/temp/download");
$array["one"] = "Download PHP scripts at dev.fyicenter.com.\r\n";
$array["two"] = "Download Perl scripts at dev.fyicenter.com.\r\n";
$bytes = file_put_contents("/temp/download/todo.txt", $array);
print("List of files:\n");
$dir = opendir("/temp/download");
while ( ($file=readdir($dir)) !== false ) {
  print("$file\n");
}
closedir($dir);
?>

This script will print:

List of files:
.
..
todo.txt
