How to Count Number of Files in Directory using PHP?

To count the number of files in a directory, we can use the built-in PHP function scandir(). The scandir() function returns an array of files and directories from the specified directory. We can then count the number of files in the array using the count() function. Here’s an example of how to use it:

$dir_path = '/path/to/my/directory';
$files = scandir($dir_path);
$num_files = count($files) - 2; // subtract 2 to exclude '.' and '..'
echo "The directory $dir_path contains $num_files files.";

In this example, we first define the directory path in a variable $dir_path. We then use the scandir() function to get an array of files and directories from the specified directory. We subtract 2 from the count of the files array to exclude the “.” and “..” directories that are returned by scandir(). Finally, we print the number of files in the directory to the screen using the echo statement.

It’s important to note that the count() function will also count subdirectories if they exist in the directory. If you only want to count files in the top-level directory, you can use a loop to iterate through the files array and count only the files. Here’s an example:

$dir_path = '/path/to/my/directory';
$files = scandir($dir_path);
$num_files = 0;
foreach ($files as $file) {
    if (is_file($dir_path . '/' . $file)) {
        $num_files++;
    }
}
echo "The directory $dir_path contains $num_files files.";

In this example, we use a foreach loop to iterate through the files array. We check whether each file is a regular file using the is_file() function. If the file is a regular file, we increment the $num_files variable. Finally, we print the number of files in the directory to the screen using the echo statement.

Conclusion:

Counting the number of files in a directory is a common task in PHP development. Fortunately, PHP provides a built-in function, scandir(), that can help us achieve this easily. By using the examples above, you should now be able to count the number of files in any directory in your PHP code. If you have any questions or comments, please leave them below.
