CURLPROTO_TFTP, I always recommend reading the cURL documentation directly as it sometimes contains better information. encode the data as multipart/form-data, This example will hopefully help you see how abstract works, how interfaces work, and how they can work together. Please be aware of the visibility of the parent fields. If the fields are private, then you are not going to see those fields in their childrens. Here is an example to change the Content Type in a POST: Please note that if you want to handle progress using CURLOPT_PROGRESSFUNCTION option, you need to take into consideration what version of PHP are you using.

The abstract keyword cannot be used to dictate properties or class constants that a derivative class must set/define. The cURL C API says you should set it to NULL, but that doesnt work in the PHP wrapper. In PHP5, for the "CURLOPT_POSTFIELDS" option, we can use: Note that if you want to use a proxy and use it as a _cache_, you'll have to do: In the long documentation, it's easy to miss the fact that CURLOPT_POSTFIELDS will set the Content-Type to "multipart/form-data" (instead of the usual "application/x-www-form-urlencoded") IFF you supply an array (instead of a query string)! cipher suite strings separated by colons. W3Schools offers free online tutorials, references and exercises in all the major languages of the web. Many hosters use PHP safe_mode or/and open_basedir, so you can't use CURLOPT_FOLLOWLOCATION. PHP 8.0 is a major update of the PHP language.

Tip: You can assign one array to the function, or as many as you like. For example: Invoking static method of abstract class should be removed. "additionally, these methods must be defined with the same (or a less restricted) visibility.". JVIR, published continuously since 1990, is an international, monthly peer-reviewed interventional radiology journal. #[Route("/api/posts/{id}", methods: ["GET"])], // Warning: strlen() expects parameter 1 to be string, array given, // Warning: array_chunk(): Size parameter expected to be greater than 0, // TypeError: strlen(): Argument #1 ($str) must be of type string, array given, // ValueError: array_chunk(): Argument #2 ($length) must be greater than 0, Human Language and Character Encoding Support.

If you have a mixture of strings starting with @ (at character) and files in CURLOPT_POSTFIELDS you have a problem (such as posting a tweet with attached media) because curl tries to interpret anything starting with @ as a file.
