To do it over a directory, I'd use an iterator.
function countLines($path, $extensions = array('php')) {
$it = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator($path)
);
$files = array();
foreach ($it as $file) {
if ($file->isDir() || $file->isDot()) {
continue;
}
$parts = explode('.', $file->getFilename());
$extension = end($parts);
if (in_array($extension, $extensions)) {
$files[$file->getPathname()] = count(file($file->getPathname()));
}
}
return $files;
}
这将返回一个数组,其中每个文件作为键和行数作为价值。然后,如果只想要总计,则只需执行 array_sum(countLines($ path));
...
That will return an array with each file as the key and the number of lines as the value. Then, if you want only a total, just do array_sum(countLines($path));
...
