fwrite函数不向文件写入任何内容

Question

I am trying to write data into a txt file, but It won't work. there is no error. it just won't work.
here is the code

if (isset($_REQUEST['submit']))
    {
        $hour = $_REQUEST['hour'];
        $family = $_REQUEST['family'];
        $how = $_REQUEST['how'];
        $will = $_REQUEST['will'];
        $fun = $_REQUEST['fun'];
        $kind = $_REQUEST['kind'];
        $device = $_REQUEST['device'];
        $study = $_REQUEST['study'];
        $agree = $_REQUEST['agree'];
        $text = "hour :" . $hour . "<br />" . "family" . $family . "<br />" . "تطابفق با درس" . $how . "<br />" . "سرگرمی های غیر مجازی : " . $will . "<br />" . "نوع سرگرمی :" . $fun . "<br />" . "kind :  " . $kind . "<br />" . "device " . $device . "<br />" . "اثیر بر درس" . $study . "<br />" . "کنترل " . $agree . "<br />" ;
        fopen('/1.txt', "r");
        fwrite('/1.txt',"hour :" . $hour . "<br />" . "family" . $family . "<br />" . "تطابفق با درس" . $how . "<br />" . "سرگرمی های غیر مجازی : " . $will . "<br />" . "نوع سرگرمی :" . $fun . "<br />" . "kind :  " . $kind . "<br />" . "device " . $device . "<br />" . "اثیر بر درس" . $study . "<br />" . "کنترل " . $agree . "<br />");
        fclose('/1.txt');

    }

do note that there is an "else" that includes all the aforementioned input fields that I used in the code , and that I am executing on localhost. thanks

You cannot write to it since you are opening it as read-only:

$handle = fopen('/1.txt', "r");

Instead:

$handle = fopen('/1.txt', "w"); // to write only, if you need to read and write use 'w+'

You also need to store fopen in a $handle so you can write to it later.

Now the first parameter for fwrite should be $handle:

fwrite($handle, "hour :" . $hour . "<br />" . "family" . $family . "<br />" . "تطابفق با درس" . $how . "<br />" . "سرگرمی های غیر مجازی : " . $will . "<br />" . "نوع سرگرمی :" . $fun . "<br />" . "kind :  " . $kind . "<br />" . "device " . $device . "<br />" . "اثیر بر درس" . $study . "<br />" . "کنترل " . $agree . "<br />");

At the end you should also close with $handle:

fclose($handle);
