<?php
mkdir (“/htdocs/testdir”, 0644);
echo “Test directory made successfully”;

this example backs up the index.php as a gzip file
<?php
$data = implode(“”, file(“index.php”));
$gzdata = gzencode($data, 9);
$fp = fopen(“index.php.gz”, “w”);
fwrite($fp, $gzdata);
fclose($fp);
?>
<?php
$dir = ‘/path/to/dir’;
if ($handle = opendir($dir))
{
while (false !== ($file = readdir($handle)))
{
if ($file[0] == ‘.’ || is_dir(“$dir/$file”))
{
// ignore hidden files and directories
continue;
}
if ((time() – filemtime($file)) > ($days *86400))
{
//note this is using the unlink function
unlink(“$dir/$file”);
}
}
closedir($handle);
}
?>
<?php
//folder to check
$folder = “C:/xampp/htdocs/xampp/wordpress/wp-includes”;
$handle = opendir($folder);
//loop through the directory
while ($file = readdir($handle))
{
$files[] = $file;
}
closedir($handle);
//display every file in folder
foreach ($files as $file)
{
echo “<a href=$folder$file>$file</a>”.”<br />”;

This is a simple line counter example which will count the lines in a text file
<?php
function LineCounter($file)
{
/* open the file */
$fh = fopen( $file, “r” );
$count = 0;
while(fgets($fh))
{
$count++;
}
fclose($fh);
return $count;
}
/*change to a file on your system*/
echo LineCounter(“phonebook.php”);
?>
Get the total disk space and used disk space
<?php
$total = disk_total_space(“c:”) / 1048576;
$used = $total – disk_free_space(“c:”) / 1048576;
echo “Total : $total MB<BR>”;
echo “Used: $used MB”;
?>
