Named arguments is a new feature introduced in PHP 8.0, which allows you to pass arguments to a function or method by specifying the parameter name along with the value. This feature provides developers with more flexibility and improves code readability.
Traditionally, in PHP, function parameters are passed by position, which means the order in which arguments are passed to a function must match the order of the parameters in the function signature. In contrast, named arguments allow you to specify which parameter you are passing the argument to, without being constrained by the order.
$lastDay = date(‘t’,strtotime(‘today’));
echo $prev_date = date(‘Y-m-d’, strtotime(date(‘Y-m-d’) .’ -1 day’));
echo $next_date = date(‘Y-m-d’, strtotime(date(‘Y-m-d’) .’ +1 day’));
Add these lines to the file /etc/phpmyadmin/config.inc.php [ubuntu]
$cfg[‘Servers’][$i][‘controluser’] = ‘root’;
$cfg[‘Servers’][$i][‘controlpass’] = ”;
The wrapping up of data and methods into a single unit (called class) is known as encapsulation. Encapsulation is a protection mechanism for the data members and methods present inside the class. In the encapsulation technique, we are restricting the data members from access to outside world end-user.
In PHP, encapsulation utilized to make the code more secure and robust. Using encapsulation, we are hiding the real implementation of data from the user and also does not allow anyone to manipulate data members except by calling the desired operation.
Variable pools are functional groupings of variables within Service Manager. There are currently four variable pools
A global variable is visible to the entire system. It begins with $G. or $lo..
A local variable is only visible to the RAD application in which it was defined. It begins with $L..
A parameter variable is defined on a parameter command panel. It may contain a value passed in from another application. By convention, parameter variables are written in uppercase letters, such as $PHASE or $GROUP.LIST. Parameter variables are invisible to the debugger.
A thread variable is only visible to the thread in which it was defined. The same variable in different threads has different values, even when the threads are spawned by the same parent.
Cross-Origin Resource Sharing (CORS) is a mechanism that uses additional HTTP headers to tell browsers to give a web application running at one origin, access to selected resources from a different origin. A web application executes a cross-origin HTTP request when it requests a resource that has a different origin (domain, protocol, or port) from its own.
