Fix PHP parse_url Function Issues

If the parse_url function is found to be ineffective, you can try the following methods to resolve it:

1. Check parameter format: Ensure that the parameters passed to the parse_url function are valid URL strings and contain the necessary protocol prefix (e.g. http:// or https://).
2. Check the PHP version: In versions older than PHP 5.4.7, there may be issues with the parse_url function when parsing certain URL formats. If you are using an older version of PHP, consider upgrading to the latest version or using alternative methods to parse URLs.
3. Check PHP configuration: In some cases, the PHP configuration file may disable the parse_url function. In the php.ini file, locate the disable_functions configuration setting and make sure parse_url is not listed. If needed, contact the system administrator or web hosting provider to make configuration changes.
4. Try alternative methods to parse the URL: If the parse_url function is unable to parse the URL, you can attempt to use other methods such as regex or string manipulation functions to extract different parts of the URL.
5. Debugging code: use the var_dump or print_r functions to print the return value of the parse_url function in order to view the parsing results and potential error information. This will help better understand the issue and make the necessary debugging and fixes.

If the above methods still cannot solve the problem, additional specific information and code examples can be provided to better understand the issue and give a more accurate solution.
