    In PHP, you can check if a directory exists using the is_dir() function. This function checks whether the specified file path is a directory. Here's a basic example of how to use it:

    $directory = '/path/to/directory';
    
    if (is_dir($directory)) {
        echo "The directory exists";
    } else {
        echo "The directory does not exist";
    }
    

    In this code, replace '/path/to/directory' with the path of the directory you want to check.

    Another way to check for the existence of a directory is by using file_exists() function. This function checks whether a file or directory exists. However, it's important to note that file_exists() will return true for both files and directories, so if you specifically want to check for a directory, is_dir() is more appropriate. Here's how you might use file_exists():

    $directory = '/path/to/directory';
    
    if (file_exists($directory) && is_dir($directory)) {
        echo "The directory exists";
    } else {
        echo "The directory does not exist";
    }
    

    In both examples, the script checks whether the specified path is a directory and then prints a message based on the result. Remember to ensure that the path you provide is correct and that your PHP script has the necessary permissions to access the directory you're checking.
