Hướng dẫn php glob only files

I know that glob can look for all files or only all directories inside a folder :

echo "All files:\n";
$all = glob("/*");
var_dump($all);

echo "Only directories\n";
$dirs = glob("/*", GLOB_ONLYDIR);
var_dump($dirs);

But I didn't found something to find only files in a single line efficiently.

$files = array_diff(glob("/*"), glob("/*", GLOB_ONLYDIR));

Works well but reads directory twice (even if there are some optimizations that make the second browsing quicker).

I finally found a solution :

echo "Only files\n";
$files = array_filter(glob("/*"), 'is_file');
var_dump($files);

But take care, array_filter will preserve numeric keys : use array_values if you need to reindex the array.

There is an easier way, just one line:

$files = glob("/path/to/directory/*.{*}", GLOB_BRACE);

the {*} means all file endings, so every file, but no folder!

10% faster compared to the solution of @AlainTiemblo, because it does not use an additional is_file check:

$files = array_filter(glob("/*", GLOB_MARK), function($path){ return $path[ strlen($path) - 1 ] != '/'; });

Instead it uses the inbuild GLOB_MARK flag to add a slash to each directory and by that we are able to remove those entries through array_filter() and an anonymous function.

Since PHP 7.1.0 supports Negative numeric indices you can use this instead, too:

$files = array_filter(glob("/*", GLOB_MARK), function($path){return $path[-1] != '/';});

No relevant speed gain, but it helps avoiding the vertical scrollbar in this post ^^

As array_filter() preserve the keys you should consider re-indexing the array with array_values() afterwards:

$files = array_values($files);

Invert regexp do the job.

preg_grep(
    ';^.*(\\\\|/)$;',
    glob("/*", GLOB_MARK),
    PREG_GREP_INVERT
);

\\\\ is for Windows backslash 🤯🔫

function glob_file_only($path){
    return array_filter(glob($path,GLOB_MARK),function($file){
        return substr($file,-1)!=DIRECTORY_SEPARATOR;
    });
}

This builds on the work of others that answered. It only touches the directory once instead of twice and it works for windows as well as linux.

This worked for me. if this helps anyone.

for file_name in glob.glob('**/*', recursive=True):
    # we get all files and dirs
    if os.path.isfile(file_name):
        # we have only the files

$all = glob("/*.*");

this will list everything with a "." after the file name. so basically, all files.
