However, some hosting companies might disable allow_url_fopen, which will break scripts relying on these methods. There should be no disadvantage to using the build-in functions instead of cURL, and unlike what is often claimed, they can be used for both POST and GET requests. The stream_context_create function mentioned before is used to gain finer control over various options related to a request. While the name of these functions do not exactly indicate that they can also be used for HTTP requests, they do actually work quite well for this, and they are also fairly easy to use. While using a library like cURL is probably one of the most popular ways to perform HTTP requests, you can also use functions such as file_get_contents and fopen. In the php-http directory, create an empty PHP file named http-stream.php, and in there, paste the code below.There are a few ways to perform HTTP requests in PHP, in this tutorial we will show how to send a POST and GET request by using the file- functions in combination with stream_context_create. Let’s step through an example of how to do so. That said, you can get up and running with it fairly quickly. and 2, check out this excellent post from Digital Ocean. If you’d like to learn more about the differences between HTTP 1.0, 1.1. However, in the five examples in this tutorial, it isn’t. Note: D epending on your use case, being limited to HTTP/1.0 might be a problem. That said, you can do quite a bit with these. Only supports a limited set of context options, such as the user agent, redirect, headers, timeout, and proxy.Only supports read (GET) not write (POST, PUT, and DELETE), requests.On the flip side, they don’t have as intuitive an interface, nor the helper utility methods that third-party libraries such as GuzzleHttp and Symfony’s HTTP client, do. Consequently, you don’t need to install a third-party library or custom extension to start using it. What’s more, they integrate with many of PHP’s core functions, such as fopen and file_get_contents. If you have configured a user_agent string using your php.ini file or the stream context, it will also be included in the request.Īs streams are part of PHP’s core, you don’t have to do much to make use of their functionality. A Host: header is sent with the request to handle name-based virtual hosts. Quoting the PHP manual: Allows read-only access to files/resources via HTTP 1.0, using the HTTP GET method. Let’s start with the options available as part of PHP's core functionality and extensions. With that, we're ready to begin ! Core PHP Functionality & Extensions To complete the first two, run the three commands below. env file so that we don't accidentally store it in the example code Throughout this tutorial, we’re going to create five PHP scripts, however, before we can get started we need to do a few things: Git (required for Composer to work fully).PHP 7.4 or newer (ideally version 8) with the cURL and OpenSSL extensions installed and enabled, and the allow_url_fopen runtime setting enabled.To complete the tutorial, you will need the following things: “ Sunset over Yellow Waters Billabong, Kakadu National Park, NT, Australia” by Geoff Whalan, which is licensed under CC BY-NC-ND 2.0. With each one, we're going to step through a code example that will download a selection of 10 images of Kakadu National Park (in Australia) using Flickr’s API, such as the one below. I won’t explore them in intimate detail, rather give a broad introduction to each one. I’ll show how to use them and cover some of their respective strengths and weaknesses. So in this post, I’m going to introduce you to five of the most common options for making them in PHP. That said, like many modern software development languages, there’s more than one way to make HTTP requests. I’d go so far as to say that it might well be one of the first things that you learn after you’ve mastered PHP’s foundations. We have to interact with all manner of APIs and external services, such as Google Cloud, Facebook, and AWS, on almost a daily basis. HTTP requests are a hallmark of modern, web-based applications-especially in PHP.
