PHP GET变量测试

Question

Trying to do something that should be very easy but not for me. I am trying to pass a variable thru a $_GET to php and store it in a text file. The variable ip is posted from an external source. I have the following: The xxx represent the ip address

$myFile = "http://xxx.xxx.x.x/iploc.txt";
$var1 =$_GET['ip'];
$fh = fopen($myFile, 'w') or die("can't open file");
fwrite($fh, $var1);
fclose($fh);

I have tried to test this by entering http://xxx.xxx.x.x/iploc.php?ip=1234 into my web address bar to see what happens. It displays the iploc.php content and does not save the ip to the text file. I know little about doing this so be kind. By looking at my server access log it seems to be getting there. Thanks in advance

Answer 1

On the server you want to write the files make this php script :

<?php

if($_SERVER['REMOTE_ADDR'] == 'xx.xx.xx.xx'){ //replace xx.xx.xx.xx by the IP of the server sending the IPs addresses
    file_put_contents('iploc.txt', $_GET['ip'], FILE_APPEND);
}

?>

Now on the external server, call this url like that :

file_get_contents('http://myserver.com/script.php?ip=xx.xx.xx.xx');
