Check whether a request is GET or POST

📝 Blog Post: Check Whether a Request is GET or POST

👋 Hey there, fellow tech enthusiasts! Today, we'll tackle a common question that often arises when working with server-side scripts: how do we check whether a request is made using the GET or POST method? 🤔

✨ Let's dive right in! 🌊

🔍 The Context: Our friend here stumbled upon a Stack Overflow post that raised this very question. They were working on a script and wanted to determine the method used for the incoming request. They even shared their initial attempt at solving the mystery:

<pre><code>if (isset($_POST)) { // do post } else { // do get } </code></pre>

🧐 But they were unsure whether this was the right way to go. Don't worry, we've got you covered! 💪

✅ The Correct Approach: To reliably check the request method in PHP, you can use the superglobal variable $_SERVER['REQUEST_METHOD']. This variable contains the method used to access the current script. 🙌

Here's an updated version of the code that follows this approach:

<pre><code>if ($_SERVER['REQUEST_METHOD'] === 'POST') { // do post } else { // do get } </code></pre>

💡 Explanation: By accessing $_SERVER['REQUEST_METHOD'], you can easily determine whether the request was made via the GET or POST method. If it's equal to "POST", you'll know that the request is a POST request. Otherwise, it's a GET request.

🔥 Pro Tip: Remember that $_POST is not used to check the request method, but rather to access the data sent via POST. So, it's not suitable for this purpose.

🌈 Let's illustrate this with an example:

Suppose you have a form on your website that allows users to submit feedback. To handle the submission appropriately, you need to differentiate between GET and POST requests. With the code snippet provided above, you can easily handle each case separately, ensuring that the user's feedback is processed correctly.

📣 Call-to-Action: Now that you know the correct way to check if a request is GET or POST, why not implement it into your own projects? Give it a try and let us know in the comments if you found this solution helpful! 😃
