The chdir() function in PHP used to change PHP’s current directory to new directory path. It takes only a single argument as new directory path.
Syntax :
bool chdir(string $new_directory_path)
Parameters Used : This function accepts only one parameter and which is mandatory to be passed.
- $new_directory_path : This parameter represents the new directory path (i.e. destination path).
Return Value : It returns a boolean operator as return value, but actually changes the current directory as desired.
Examples :
Input : CWD: /home/
chdir("gfg")
Output : CWD: /home/gfg
Explanation : Current working directory(CWD)
was changed from '/home/' to '/home/gfg'.
Input : CWD: /home/Documents/
chdir("foldergfg/inside_folder_gfg")
Output : CWD: /home/Documents/foldergfg/inside_folder_gfg
Explanation : Current working directory (CWD)
was changed from '/home/Documents/' to '/home/
Documents/folder_gfg/inside_folder_gfg'.
Errors and Exceptions :
This function returns TRUE on success and FALSE on failure. So, it gives an error / E_WARNING on failure. Generally, failure conditions occur when the destination directory path is not valid.
Applicable versions :
This function is applicable in PHP 4, PHP 5, PHP 7.

<?php
echo getcwd () . "<br>" ;
chdir ( "testing_gfg" );
echo getcwd ();
?>
