Question

我正在尝试在CodeIgniter的视图文件中编写一些JSON数据。

但它显示错误：

Message: fopen() [function.fopen]: Filename cannot be empty

控制器功能如下：

public function write_in_a_view_file() {

    $data = array();
    $data['title'] = "Write This Title In a View File";

    $view_file = $this->load->view('result.php');

    $fp = fopen($view_file, 'w');
    fwrite($fp, json_encode($data));
    fclose($fp);

}

Answer 1

您可以使用CodeIgniter文件助手。

public function write_in_a_view_file() {
    $data = array();
    $data['title'] = "Write This Title In a View File";

    $this->load->helper('file');
    $new_file_path = base_url() . '/path/to/file.php'; // modify this line to point to the actual location of the file
    write_file($new_file_path, json_encode($data));
}

Answer 2

fopen函数有两个参数，第一个必须是文件名，而你没有传递给第一个参数。
