How to save the running results in php? (not code)

with the following code 

<script src="http://pv.sohu.com/cityjson" ></script>
<script type="text/javascript">
   document.write("IP:"+returnCitySN.cip);
</script>
<br>
<script src="http://ip.ws.126.net/ipquery" ></script>
<script type="text/javascript">
      document.write(":"+ localAddress.province+"<br>:"+localAddress.city);
</script>

the front browser does not have permission to write files. You can use the file_put_contents function in PHP to write to 1.txt

mysql to learn about

.

if you want the client to save 1.txt
, you can download the file and let the user choose to save

.

if you want to save on the server side, you need to send a post request to the server using a php page or js, and then save it to the server with a file operation at the back end.

RE:
at the front end, you need to use ajax to send Post requests. Of course, there is also a lot of room to expand the back-end access records. For example, if you visit one file at a time, you can also open the file for appending. You can take some time to learn about fopen,fwrite and other file-related operations

. 
// php


function saveUserIp($content,$append=0){

    $path     = 'folderName/';
    $name     = 'ipRecord';

    $filename = ($append ? $name : microtime(true) ).'.txt';


    $file     = fopen($path.$filename, $append?'a':'w') or die("!");

    fwrite($file, $content."\n");
    fclose($file);

}

//  
saveUserIp($postContent,1);

//  
saveUserIp($postContent);
