php - 用于搜索目录和仅限.jpg的glob

Question

What if I want to search for a only subdirectories AND certain file types. Ex. I have a folder named “stuff” where random stuff is uploaded. And say I want to search for just subfolders AND .jpg files within “stuff” and nothing more. I know to search for only .jpg is…

$array = glob(‘stuff/{*.jpg}’, GLOB_BRACE);

and to search for only subdirectories is…

$array = glob(‘stuff/*’, GLOB_ONLYDIR);

…but how do I combine the two without getting any other unwanted files? Is there a pattern for subirectories for GLOB_BRACE?

Answer 1

This recursive function should do the trick:

function recursiveGlob($dir, $ext) {
    $globFiles = glob("$dir/*.$ext");
    $globDirs  = glob("$dir/*", GLOB_ONLYDIR);

    foreach ($globDirs as $dir) {
        recursiveGlob($dir, $ext);
    }

    foreach ($globFiles as $file) {
        print "$file
"; // Replace '
' with '<br />' if outputting to browser
    }
}

Usage: recursiveGlob('C:\Some\Dir', 'jpg');

If you want it to do other things to the individual file, just replace the print "$file " part.

The function can be more specific in its glob searches and only match directories as well as files with the specified file extension, but I made it this way for simplicity and transparency.
