There's a lot of ways. The older way is scandir
but DirectoryIterator
is probably the best way.
There's also readdir
(to be used with opendir
) and glob
.
Here are some examples on how to use each one to print all the files in the current directory:
DirectoryIterator
usage: (recommended)
foreach (new DirectoryIterator('.') as $file) {
if($file->isDot()) continue;
print $file->getFilename() . '<br>';
}
scandir
usage:
$files = scandir('.');
foreach($files as $file) {
if($file == '.' || $file == '..') continue;
print $file . '<br>';
}
opendir
and readdir
usage:
if ($handle = opendir('.')) {
while (false !== ($file = readdir($handle))) {
if($file == '.' || $file == '..') continue;
print $file . '<br>';
}
closedir($handle);
}
glob
usage:
foreach (glob("*") as $file) {
if($file == '.' || $file == '..') continue;
print $file . '<br>';
}
As mentioned in the comments, glob
is nice because the asterisk I used there can actually be used to do matches on the files, so glob('*.txt')
would get you all the text files in the folder and glob('image_*')
would get you all files that start with image_
