如何使用PHP计算目录中的所有文件？ （例如124个文件）

Question

I'm trying to figure out how I can count all of my XML files in one directory. How can I do this with PHP?

Answer 1

$dir = "random_directory/";
$files = glob("$dir*.xml");
$count = $files !== false ? count($files) : 0;
echo $count;

Just change $dir to your directory.

Answer 2

you can use glob

$count = 0;

foreach (glob("*.xml") as $filename) {
    echo $filename;  //gives you the file name
    $count++;
}

echo $count;

or per MitMaro, simply just get the # of xml files without accessing file information:

echo count(glob("*.xml"));

Answer 3

$files = scandir('/path/to/dir/');
$count = 0;
foreach ($files as $file) {
    if (strtolower(substr($file, 4)) == '.xml') {
        $count++;
    }
}
