![]() To that end, we must make our code as easy to read and understand as possible. One of our core tenets of development is that code is read more than it’s written. ![]() We use the setcookie() function to set data.įixing Long Functions With The Extract Function Refactoring by warren5236 PHP’s cookie support is essentially a key-value store. PHP’s header() function has the same limitation. This is because cookies are set in the header section of the HTTP request. We must set our cookies before we start outputting the HTML of our page. It does this with several helper functions and a global variable. PHP has built-in support for cookies all the way back to version 4.0. Using HTTP will encrypt the cookie data but HTTP won’t. We’ll discuss sessions in our next article.Ĭookies are transmitted back to the server in the HTTP headers. To store sensitive data securely we should use sessions instead. We should not store sensitive data in cookies since it could be potentially manipulated by a malicious user. Those types of cookies are referred to as 3rd-party cookies because they’re being requested from a 3rd-party server, not the user or web server directly involved in the request. A cookie is generally used to keep track of information such as a unique identifier of the person requesting the resource so we can build the page specifically tailored to them.Ĭookies have a bad rap because they’re used to track users across multiple sites for advertisers which is why every site on the internet needs to have a banner telling its users that it uses cookies. This information will then be sent back to our web server whenever the user makes a request. What is a Cookie?Ī cookie is a small file (maximum of 4KB) that allows us as developers to store information on our user’s computer. In this article, we’ll discuss how to use cookies in our PHP applications. Thankfully, every modern browser supports cookies to keep track of our users between requests. We could add a unique identifier to every URL but this makes our URLs hard to generate, hard to read, and hard to share. Working With Cookies in PHP by warren5236Ī core functionality of any modern web application is keeping track of our users between web requests.
