renaming files

Here is the situation.. I have one folder in which i have lots of files with name

x1.html x2.html x3.html.... and so on..

and i want to change them into y1.html y2.html y3.html and so on..

Is it possible in php??

 

$prefix = 'y';

foreach (glob('path/to/files/*.html') AS $file)
{
     preg_match('/^.*([0-9]+\.html)/', $file, $filename);
     rename($file, $prefix . $filename[1]);
}

PHP:

Will take the last part of the old filename (eg: x1.html), and change the rest to the specified prefix. So in this case x becomes y and the rest stays the same.

(Tested)

 

The problem you describe would be solved by recursively calling php's rename() function. The function is described at the php site: rename() . . . . as explained by nico
