How Can I Reliably Get a List of All Files in a Directory Using PHP?

Getting the Names of All Files in a Directory with PHP

When attempting to retrieve file names from a directory using the readdir() function, you may encounter unexpected results with file names appearing as '1' instead of their actual names. This issue can be resolved by adopting an alternative approach.

Solution: Using glob()

Rather than using opendir() and readdir(), consider utilizing the glob() function. glob() provides a convenient means of matching files using wildcards and returning an array of matched file paths.

Implementation:

To retrieve all files within a specified directory, you can use the following code:

foreach(glob($log_directory.'/*.*') as $file) {
    // ...
}

In this code, $log_directory represents the directory from which you wish to obtain file names. The wildcard *.* matches files with any name and extension.

By iterating over the array returned by glob(), you can access the actual file names instead of the '1' values encountered with readdir().
