How Can I Convert a Complex cURL Command to PHP cURL?

Convert Command Line cURL to PHP cURL

When faced with a complex cURL command like the one provided, converting it to PHP cURL can be a daunting task. Here's a step-by-step guide to help you translate the command and incorporate it into your PHP script:

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

1. Variables:
Identify and replace the static values with variables in your PHP script. For instance, @test.png should become $filename and http://hostname/@api/deki/pages/=TestPage/files/= becomes $pageurl.

2. Initialization and Options:
Initialize the cURL session using curl_init():

$ch = curl_init($theurl);

Then, configure the options:

• Set the cookie file using CURLOPT_COOKIE.
• Specify the HTTP method as PUT using CURLOPT_CUSTOMREQUEST.
• Enable binary transfer by setting CURLOPT_BINARYTRANSFER to TRUE.
• Add the HTTP header for content type using CURLOPT_HTTPHEADER.
• Set the HTTP version to 1.0 with CURLOPT_HTTP_VERSION.

3. Data Configuration:
Use CURLOPT_POSTFIELDS to set the binary data to be sent. This would be the contents of test.png:

curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

4. Execution and Output:
Execute the cURL request:

$response = curl_exec($ch);

And retrieve the output:

$output = curl_getinfo($ch, CURLINFO_EFFECTIVE_URL);

Additional Resources:
Refer to the PHP manual for detailed documentation on curl_setopt(): http://www.php.net/manual/en/function.curl-setopt.php
