chdir() to change the directory to a different one. This function returns true on success and false on Failure. We have used getcwd() function to get the current directory location.

To change from current directory to one step up directory

echo getcwd();
chdir('..');
echo "<br>";
echo getcwd();

As chdir() returns TRUE or FALSE we can use if condition to post message.

echo getcwd();
echo "<br>";
if(@chdir('test_dir2')){
echo getcwd();
}else{
echo " Wrong Directory ";
}
