判斷檔案存在與否- $filename = "example.txt";
- if (file_exists($filename)) {
- echo "文件存在.";
- } else {
- echo "文件不存在.";
- }
- $filename = "example.txt";
- $fileContents = file_get_contents($filename);
- echo "内容: " . $fileContents;
- $filename = "example.txt";
- $newContent = "新內容";
- file_put_contents($filename, $newContent);
- echo "内容已更新.";
- $filename = "example.txt";
- $appendContent = "追加的内容";
- file_put_contents($filename, $appendContent, FILE_APPEND);
- echo "已追加內容至檔案中.";
