Jul 25, 2016 am 08:51 AM

  1. //Initialization

  2. $ch = curl_init();

  3. //The local file address to be uploaded"@F:/xampp /php/php.ini" when uploading, there must be an @ symbol in front of the upload path

  4. $furl = "@F:/xampp/php/php.ini";
  5. $post_data = array (
  6. "upload" => $furl
  7. );

  8. //Where does CURLOPT_URL refer to submission? Equivalent to the path specified by "action" in the form

  9. $url = "http://localhost/test/curl/curl_post.php";

  10. //Set variables

  11. curl_setopt($ch , CURLOPT_URL, $url);
  12. curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);//Whether the execution result is returned, 0 is returned, 1 is not returned
  13. curl_setopt($ch, CURLOPT_HEADER, 0);//Parameter settings, Whether to display the header information, 1 means display, 0 means not display

  14. //Fake web page source address, fake form submission from Baidu

  15. curl_setopt($ch, CURLOPT_REFERER, "http:// www.baidu.com");

  16. //Form data, the regular form setting value is non-0

  17. curl_setopt($ch, CURLOPT_POST, 1);

  18. < ;p>curl_setopt($ch, CURLOPT_TIMEOUT, 1);//Set the maximum curl execution timeout

  19. //When using an array to provide post data, the CURL component is probably for compatibility with @filename This way of writing uploaded files,

  20. //default content_type is set to multipart/form-data. Although it has no impact on most web servers, there are still a small number of servers that are incompatible. The conclusion drawn by this article is that when there is no need to upload files, try to http_build_query the data submitted by the post and then send it out, which can achieve better compatibility and smaller request data packets.
  21. curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);

  22. //Execute and get the results

  23. $output = curl_exec($ch);
  24. if($outopt === FALSE)
  25. {
  26. echo "
    ","cUrl Error:".curl_error($ch);
  27. }
  28. // Release the cURL handle
  29. curl_close($ch);
  30. ?>

Copy code
File 2: curl_post.php

    echo "
    ";
  1. var_dump($_FILES);
  2. ?>
Copy the code
The results are as follows:

    array(1) {
  1. ["upload"]=>
  2. array(5) {
  3. ["name"]=>
  4. string(7) "php.ini"
  5. ["type" ]=>
  6. string(24) "application/octet-stream"
  7. ["tmp_name"]=>
  8. string(24) "F:xampptmpphpB2D1.tmp"
  9. ["error"]=>
  10. int(0 )
  11. ["size"]=>
  12. int(46217)
  13. }
  14. }

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
