PHP resembles Perl in terms of syntax and features. Both languages share similar characteristics, such as a focus on web development and support for regular expressions.

The correct option is 1. An example of a superglobal in PHP is $_POST. The $_POST superglobal is used to collect form data sent with the POST method. When an HTML form is submitted with the POST method, the form data is available in the $_POST superglobal as an associative array. The $_POST superglobal allows you to access the form data and process it in your PHP script. It is commonly used to handle form submissions and perform actions based on the submitted data. Other superglobals in PHP include $_GET, $_REQUEST, and $_SERVER. Learn more: https://www.php.net/manual/en/reserved.variables.post.php

The Exception::__toString method in PHP allows you to define a custom string representation for an exception object. It is automatically called when you try to convert an exception object to a string. Learn more: http://php.net/manual/en/exception.tostring.php

A constant in a PHP class is indeed defined using the const keyword. It allows you to define a constant within a class by specifying the constant name, the assignment operator =, and the desired value. For example: const CONSTANT_NAME = value; Constants are used to store values that remain the same throughout the execution of a script and cannot be changed once defined. They provide a convenient way to define and use fixed values within a class. Refer to: http://php.net/manual/en/language.constants.php

To include a file in your PHP script and continue execution even if the file is not found, you would use the include() statement. If the file is not found, a warning will be generated, but the script execution will continue without causing a fatal error.

In PHP, the $_GET superglobal is used to collect data sent in the URL's query string. When data is sent to the server through the URL using the GET method, the values are appended to the URL as key-value pairs in the query string. The $_GET superglobal allows access to these values by using the corresponding key as an index. It is commonly used to retrieve parameters or values passed through the URL.

A static method in PHP OOP is a method that belongs to the class itself rather than an instance of the class. It can be accessed using the class name without creating an object of the class.

In this case, you would use the float data type to store a price that includes cents in a variable in your PHP script. The float data type allows for the representation of real numbers with a decimal point, which is suitable for storing prices that may have fractional values, such as cents. Integer data type is not suitable as it does not allow for decimal points. String data type could be used, but it is more appropriate to use float to perform arithmetic calculations if needed.

To sanitize a string in PHP, you can use the filter_var() function with the FILTER_SANITIZE_STRING flag. This flag specifically sanitizes the string by removing HTML tags and encoding special characters to make the string safe for output. The filter_var() function provides an easy and efficient way to sanitize strings in PHP. For more details, see: http://php.net/manual/en/function.filter-var.php

In the context of PHP, OOP stands for Object-Oriented Programming. It is a programming paradigm that focuses on creating objects and defining their behavior using classes, inheritance, encapsulation, and polymorphism. The correct option is "Programming." For further details, refer to the PHP documentation on object-oriented programming: http://php.net/manual/en/language.oop5.php
