利用 PHP 实现精确代码行数统计 - 包含单个文件及整个目录

function countLinesInSingleFile($filePath) {
// 打开并读取文件内容
$file = fopen($filePath, 'r');
if (!$file) return false;

$lineCount = 0;

while (!feof($file)) {
fgets($file);
$lineCount++;
}

fclose($file);

// 这里我们忽略了空行与注释的数量以达到“有效”代码行计数的目的，
// 若需包含这些，则无需任何修改

return $lineCount;
}

// 使用示例：
$singleFilePath = './example.php';
echo "The number of lines in '$singleFilePath' is: ", countLinesInSingleFile($singleFilePath);

function countLinesRecursively($directoryPath) {
$totalLineCounts = [];

foreach (new RecursiveIteratorIterator(new RecursiveDirectoryIterator($directoryPath), RecursiveIteratorIterator::SELF_FIRST) as $item) {
if ($item->isDir()) continue; // 跳过非文件

if(pathinfo($item->__toString(), PATHINFO_EXTENSION) === 'php') {
$count = count(file($item));
array_push($totalLineCounts, ['filename' => $item->getRealpath(), 'lines_count' => $count]);
}
}

// 计算总行数
$sumOfAllLines = array_sum(array_column($totalLineCounts, 'lines_count'));

echo "\nThe total number of code lines across all .php files under directory '$directoryPath': {$sumOfAllLines}";

// 返回每个文件的具体统计数据（可选）
return $totalLineCounts;
}

// 示例用法:
$direcotryToScan = '.';
$countResults = countLinesRecursively($direcotryToScan);
