Many times you need to get the list of contents of a directory in php scripts. You can get list of files and directories in a directory by using following function. It returns the list of items as an array.
[php]
function getdirlist($dir){
return array_diff( scandir( $dir ), Array( “.”, “..” ) );
}
[/php]
This function works in php5 environment only.
But if there are too many files in the folder you can use the below function to list each of them.
[php]
function getlist($directory){
$results = array();
// create a handler for the directory
//$directory=”.”;
$handler = opendir($directory);
// keep going until all files in directory have been read
while ($file = readdir($handler)) {
// if $file isn’t this directory or its parent,
// add it to the results array
if ($file != ‘.’ && $file != ‘..’){
$results[] = $file;
}
}
// tidy up: close the handler
closedir($handler);
return $results;
}
[/php]

A brief tutorial on usage of chown linux command
What is this tool for..
It is to change the ownership of a file.
you should use like
chown newuser filename
To change owenership of all files and directories in current directory use *
chown newowner *
To change owner ship of all files and sub directories and files recursively
chown -R newowner .
You just wanted to remove a directory with large no of files in it and you issued the command
$rm -rf *
But the rm throws an error argument list too long, then how to remove the files?
Here is a simple fix that will allow you to remove large no of files easily..
First copy and paste the below code in the terminal
function large_rm() { while read line1 ; do rm -f ./$line1; done; };
Then cd to that directory where you need to remove the files then issue the command
ls -l |large_rm
Thats it.. it will remove all the files in that directory within seconds :)
Ok.. this is a life save for most of the webmasters. Take the scenario when you have to move from one server from other. This work only if you are on a dedicated or vps server. You need wget to do this job.

How much functionality can you pack into a 64×64 square? That’s the basic question behind many dockapps – utilities that can be run on the “dock” of many popular desktop environments.
