    echo 'failed';

But i cant any extracted file whether it show 'ok' in browser. What is the mistake in the code i cant found. another thing to download the zip file from the "http://wordpress.org/latest.zip" site. i used the code written bellow. Here also i cant download the file.

$foo = system('wget http://www.myserver.com/file.txt ~',$output);

Answer 1

It appears that the ZipArchive needs a reference to the library containing that class.

Also make sure that in your php.ini file, you have enabled the library that enables zip files functions to work on your server. (The zip extension is loaded by default under PHP 5.3)

Again, make sure the directory you want to extract the files has write permissions.

Answer 2

You could also use:

exec('wget http://wordpress.org/latest.zip -O temp.zip');
exec('unzip temp.zip -d /somedir');
