Why do we need to set a dynamic base URL in CodeIgniter 4?
Basically, In most cases, we need to shift our CodeIgniter application from a Local Server to a Live Server and vice-versa. So, every time we have to change the base URL from the config.php file. It takes a little bit more time and also increases 1 more step every time. A good developer already has solutions to save time.
So here, I have a solution for you. you can try this code on \application\config\config.php:
Step1: Get HTTP or HTTPS from URL
$config['base_url'] = ((isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == "on") ? "https" : "http");
this line of code will help you to detect the HTTP or HTTPS. this is also a major issue in many cases. because when you SSL certificated expired or user tries request with HTTP then fixed URL return error or creates a bug.
Step2: Get Host or domain name from URL
$config['base_url'] .= "://".$_SERVER['HTTP_HOST'];
Step3: get Script Name from URL
$config['base_url'] .= str_replace(basename($_SERVER['SCRIPT_NAME']),"",$_SERVER['SCRIPT_NAME']);
So, here I concatenated or combined 3 lines in $config[‘base_url’] to set customizable base URL in CodeIgniter. I think this is the easiest and the best solution for CodeIgniter 4 dynamic base URL or Site URL.
$config['base_url'] = ((isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == "on") ? "https" : "http"); $config['base_url'] .= "://".$_SERVER['HTTP_HOST']; $config['base_url'] .= str_replace(basename($_SERVER['SCRIPT_NAME']),"",$_SERVER['SCRIPT_NAME']);
