Using Arrays in cURL POST Requests
To facilitate the posting of arrays via cURL POST requests, it is crucial to ensure the proper formatting of the array within the $fields variable. The issue in the provided code lies in the incorrect construction of the images array.
Solution:
The recommended approach is to utilize the http_build_query function, which automatically generates a string with the appropriate array syntax. This function requires the array to be structured as follows:
<code class="php">$fields = array( 'username' => "annonymous", 'api_key' => urlencode("1234"), 'images' => array( urlencode(base64_encode('image1')), urlencode(base64_encode('image2')) ) ); //url-ify the data using http_build_query $fields_string = http_build_query($fields);</code>
By reformatting the array in this manner and employing http_build_query, the cURL request will correctly transmit the images array as an array of strings to the API.
