PHP chdir Function: Changing the Working Directory

The chdir function changes PHP's current working directory to the specified path.

Signature: bool chdir(string $directory) Parameter $directory is the new working directory.

It returns TRUE on success or FALSE on failure.

Example:

<?php
// current directory
echo getcwd()."
";
chdir('public_html');
// current directory
echo getcwd()."
";
// output
/home/vincent
/home/vincent/public_html
?>

The example prints the directory before and after calling chdir, showing the change from the original path to public_html.
