What should I do if the php fopen file does not exist?

Determine whether the folder exists in php. If it does not exist, create a new one.

Introduction: During the project development process, sometimes it is necessary to read or generate files in the specified folder. At this time, you need to first determine whether the folder exists, and if it does not exist, create a new one.

Method:

//判断文件夹是否存在，没有则新建。
if (!function_exists('mkdirs')) {
    function mkdirs($dir, $mode = 0777)
    {
        if (is_dir($dir) || @mkdir($dir, $mode)) {
            return true;
        }
        if (!mkdirs(dirname($dir), $mode)) {
            return false;
        }
        return @mkdir($dir, $mode);
    }
}

Actual use:

    //判断文件夹是否存在
    public function test()
    {
        $localhost_path = ROOT_PATH . 'public/static/unit_record/';
        $result = mkdirs($localhost_path);//这里会返回true
    }
