Working with files and folders is a common task in PHP development. Sometimes, we may need to extract the folder path from a file path for further processing. In this blog post, we’ll explore a simple PHP function that can help you get the folder path from a file path.

How to get folder path from file path in PHP?

To get the folder path from a file path, we can use the built-in PHP function dirname(). The dirname() function returns the directory name component of a path. Here’s an example of how to use it:

$file_path = '/path/to/myfile.txt';
$folder_path = dirname($file_path);
echo $folder_path; 
// Output: /path/to

In the example above, we first define the file path in a variable $file_path. We then use the dirname() function to extract the folder path and store it in a variable $folder_path. Finally, we print the folder path to the screen using the echo statement.

If the file path does not contain a directory separator (e.g., if the file is in the root directory), dirname() will return “.” (i.e., the current directory). Therefore, it’s a good practice to check whether the folder path returned by dirname() is the same as the file path itself. Here’s an example:

$file_path = 'https://cdn.laraveltuts.com/myfile.txt';
$folder_path = dirname($file_path);
if ($folder_path === $file_path) {
    $folder_path = '.';
}
echo $folder_path; 
// Output: .

In this example, we first define a file path that does not contain any directories. We then use the dirname() function to extract the folder path and store it in a variable $folder_path. We check whether $folder_path is the same as $file_path, and if so, we set $folder_path to “.” (i.e., the current directory).

Conclusion:

Getting the folder path from a file path is a common task in PHP development. Fortunately, PHP provides a built-in function, dirname(), that can help us achieve this easily. By using the examples above, you should now be able to extract the folder path from any file path in your PHP code. If you have any questions or comments, please leave them below.
