"file_get_contents(): php_network_getaddresses: getaddrinfo failed: Name or service not known" - Troubleshooting Connectivity Issues

The "file_get_contents(): php_network_getaddresses: getaddrinfo failed: Name or service not known" error indicates that PHP is unable to resolve the domain name provided to the function. This typically occurs due to DNS configuration issues.

The issue stems from your server's inability to connect to the outside internet. By modifying the name servers in your /etc/resolv.conf file to alternative nameservers, you may resolve the DNS issue and enable your PHP script to download the image successfully.

Additional Troubleshooting Steps:

• Check your network settings: Ensure that your server has a stable internet connection and is not experiencing any firewall issues.
• Verify DNS resolution: Use tools like "dig" or "nslookup" to confirm that your server can resolve the image's domain name correctly.
• Inspect your hosts file: Check your /etc/hosts file for any overridden DNS entries that may conflict with the image's domain name.
• Update PHP version: Use a more recent version of PHP that may have updated DNS lookup capabilities.
• Enable "allow_url_fopen" directive: Set the "allow_url_fopen" directive in your PHP configuration (php.ini) to "On" to enable PHP to open remote URLs.
