These are 'Magic Constants', and this is how we can use them. Learn how to regenerate and update WordPress media and image sizes both programmatically (without plugin), and also with a handy plugin. Regenerate WordPress media image sizes, programmatically by Gav Measuring script/code execution time in PHP, microtime by Gav įind bottlenecks, optimise and clean your code, and speed up your apps by measuring the execution time of your PHP scripts using microtime. Use these methods in JavaScript to help optimise your code. Measuring code execution performance is an important way to identify bottlenecks. Measuring code execution performance in JavaScript by Gav Learn about Parsing and Writing YAML files using Symfony's YAML component. In this tutorial we will look at using YAML in PHP. Reading/Parsing and Writing YAML files, PHP Symfony by Gav Use Implements to implement interfaces and types, and extends to inherit from classes. Learn the difference between implements and extends in TypeScript. Implements and Extends, Object Oriented TypeScript by Gav Discover their benefits and best practices. Learn how to improve code readability and performance by using guard clauses in JavaScript. How to/why use guard clauses in JavaScript by Gav Learn how to create and register your own WordPress shortcodes to add dynamic content to your posts and pages. Next, we use curl_exec to run curl and save the response to the ‘$response’ variable (remember we are returning the response as a string) and, finally, we close curl.Īt this point you can do whatever it is that you wanted to do with the response!Ĭreate, register and use shortcodes in WordPress by Gav Note: For a full explanation of the parameters we are using, please refer to the PHP manual for curl_setopt. This will Base64 encode your string and set the right ‘Authorization’ headers, basically saving you from having to do it yourself. ‘CURLOPT_USERPWD’ sets the username and password for Basic Authentication.If this doesn’t work for you, try setting it to ‘CURLAUTH_ANY’ and have the library find the right usage. We are setting this to ‘CURLAUTH_BASIC’, which is default. ‘CURLOPT_HTTPAUTH’ specifies the authentication method to use.‘CURLOPT_RETURNTRANSFER’ is being used to set the response to a string value.In this example I’ve added a placeholder URL. ‘CURLOPT_URL’ is used to specify the URL to call.Specifically, we are setting the following: $username = 'gav' Ĭurl_setopt($ch, CURLOPT_RETURNTRANSFER, 1) Ĭurl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC) Ĭurl_setopt($ch, CURLOPT_USERPWD, "$username:$password") Īfter intialising curl, we are using curl_setopt to configure the options. If you want to make a login call using Basic Authentication via PHP Curl then the snippet below should help you. For several simple security use-cases, Basic Authentication is a perfectly acceptable solution to use, as long as you are aware that it isn’t completely secure. Despite this, you will still find fairly wide spread Basic Authentication usage because of how easy it is to implement and manage. It is worth considering that Basic Authentication has security limitations when compared to something like OAuth because your login credentials are included with each request. Which becomes (when Base64 encoded): Authorization: Basic ZXhhbXBsZV91c2VybmFtZTpleGFtcGxlX3Bhc3N3b3Jk The basic (decoded) header format is: Authorization: Basic example_username:example_password The ‘Authorization’ field contains the word ‘Basic’ followed by a colon seperated, Base64 encoded string containing the username and password. To use Basic authentication a client must attach an ‘Authorization’ field to their request. What is Basic Authentication?īasic authentication is a way for a HTTP user agent to pass a username and password during a request. Note: For this tutorial I am going to assume that you have the PHP Curl extension installed and enabled on your server. One of the most common forms of HTTP authentication is Basic Authentication, owing to how easy it is to use and implement. When sending a request to an API, often it will require some form of Authentication. In this tutorial we will have a ‘basic’ look at Basic Authentication, and how to use Basic Authentication with PHP Curl. Facebook Share Twitter Share LinkedIn Share
