Translating Command Line cURL to PHP cURL

When working with APIs that support cURL, it can be challenging to translate these commands from the command line to a PHP script. This article provides a detailed solution for converting a specific cURL command to PHP.

Original cURL Command:

curl -b cookie.txt -X PUT \
     --data-binary "@test.png" \
     -H "Content-Type: image/png" \    
     "http://hostname/@api/deki/pages/=TestPage/files/=test.png" \
     -0

PHP cURL Translation:

To replicate this command in PHP, you can follow these steps:

1. Define variables for the dynamic parts of the URL and filename:

   $pageurl = "http://hostname/@api/deki/pages/=TestPage/files/=";
   $filename = "test.png";

2. Construct the full URL:

   $theurl = $pageurl . $filename;

3. Initialize the cURL request:

   $ch = curl_init($theurl);

4. Set cURL options to match the original command:

   // Set cookie (if available)
   curl_setopt($ch, CURLOPT_COOKIE, ...); // -b
   
   // Set method to PUT
   curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT'); // -X
   
   // Enable binary transfer for file upload
   curl_setopt($ch, CURLOPT_BINARYTRANSFER, TRUE); // --data-binary
   
   // Set content type
   curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: image/png']); // -H
   
   // Force HTTP/1.0 version
   curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_0); // -0

5. ... (Additional code that follows)

By following these steps, you can successfully translate your command line cURL command to PHP, allowing you to interact with the API from your script. For more details on cURL options, refer to the PHP manual: http://www.php.net/manual/en/function.curl-setopt.php
