PHP - data not properly used from GET parameter

This is my code: 

file_put_contents('ip.txt', $ip); // ip is 62.227.217.95 and is saved correctly into ip.txt file

$returned_content = get_data('https://xxx:[email protected]/geoip/v2.1/city/' . $ip);

file_put_contents('content.txt', $returned_content); // file is empty, nothign saved

You can see what's the problem in the comments.

BUT when I put the ip directly instead of from GET parameter:

file_put_contents('ip.txt', $ip); // ip is 62.227.217.95 and is saved correctly into ip.txt file

$returned_content = get_data('https://xxx:[email protected]/geoip/v2.1/city/62.227.217.95');

file_put_contents('content.txt', $returned_content); // content is written correctly, everything fine.

What am I doing wrong here? I also tried urldecode($ip)

Please help

Solution

  • There were invisible chars, I solved it with: preg_replace('/[\x00-\x1F\x7F]/u', '', $ip)
