我撰寫了一個函式來查找特定目錄及其子目錄中的檔案。您可以輸入帶或不帶擴展名的檔案名（basename vs. filename）。第二個引數是要搜索的路徑。檔案在給定目錄中時找到，但是，如果它在子目錄中，則找不到。我嘗試利用函式的 recursive 呼叫來查看子目錄。有什么我想念的想法嗎？
public function findFileInPathRecursive($file_to_find, $path) {
if (substr($path, -1) != "/") $path .= "/"; // Add slash at path's end
$files = scandir($path);
foreach($files as $file) {
if (substr($file, 0, 1) == ".") continue; // skip if "." or ".."
if (is_dir($path.$file)) { // if "file" is a directory, call self with the new path
$new_path = $path.$file;
return $this->findFileInPathRecursive($file_to_find, $new_path);
}
else {
if (pathinfo($file)['basename'] == $file_to_find OR pathinfo($file)['filename'] == $file_to_find) {
return $path.$file;
}
}
}
return false;
}

我相信return $this->findFileInPathRecursive($file_to_find, $new_path);當第一個子檔案夾不包含該檔案時，這將導致提前回傳。
您可以通過僅在找到檔案時回傳來避免。
if($found = $this->findFileInPathRecursive($file_to_find, $new_path)) {
return $found;
}
public function findFileInPathRecursive($file_to_find, $path) {
if (substr($path, -1) != "/") $path .= "/"; // Add slash at path's end
$files = scandir($path);
foreach($files as $file) {
if (substr($file, 0, 1) == ".") continue; // skip if "." or ".."
if (is_dir($path.$file)) { // if "file" is a directory, call self with the new path
$new_path = $path.$file;
// We only want to return file
if($found = $this->findFileInPathRecursive($file_to_find, $new_path)) {
return $found;
}
}
else {
if (pathinfo($file)['basename'] == $file_to_find OR pathinfo($file)['filename'] == $file_to_find) {
return $path.$file;
}
}
}
return false;
}
