If you have used a terminal before, whether Windows or Linux, you are probably familiar with the cd command.
This command allows us to change directory to any location within the filesystem. This enables us to quickly and efficiently switch to various locations in the filesystem without the need for a Graphical Interface.
PHP chdir() Function
The chdir() function in PHP allows us to change the directory in PHP. The function syntax is as shown:
chdir(string $directory): bool
The function accepts one parameter:
directory- the path to the target directory as a string value.
The function returns a Boolean value with True on success and False failure.
Example Function Usage
The following example demonstrates how to use the chdir() function to change the working directory.
<?php
// current directory
echo getcwd() . "\n";
chdir('/var/www');
// current directory
echo getcwd() . "\n";
?>
The above code should change the working directory from pwd to /var/www directory. Resulting output:
/home/debian
/var/www
