The correct option is: "Use the break statement to terminate the current loop." The break statement in PHP is used to stop the execution of the current loop and move to the line immediately following the loop. It allows you to prematurely exit the loop when a certain condition is met. Learn more: https://www.php.net/manual/en/control-structures.break.php

In PHP, the string data type is used to store a sequence of characters. It can hold alphanumeric characters, symbols, and special characters.

A potential issue when working with the $_GET superglobal in PHP is security vulnerabilities. It is crucial to properly validate and sanitize the input received through $_GET to prevent attacks like SQL injection or cross-site scripting. Data loss during transmission or limited data storage capacity are not directly related to the $_GET superglobal. Compatibility issues with web browsers are not specifically associated with $_GET but rather with the general functionality of web applications.

The == operator is a comparison operator in PHP. It is used to compare two values for equality. For example, $num1 == $num2 will return true if $num1 is equal to $num2, and false otherwise. The == operator checks for equality of values without considering the data types. Learn more: https://www.php.net/manual/en/language.operators.comparison.php

The correct option is 2. Superglobals in PHP, such as $_POST or $_GET, are accessed just like any other variable. You can use them within functions, loops, classes, or conditional statements without the need for any special syntax or declarations. Superglobals are always available in all scopes, meaning you can access them from anywhere within your PHP script, regardless of where you are in the script's execution flow. This makes them convenient for accessing data from different parts of the script without having to pass variables explicitly.

After creating a MySQL database and executing your queries, it's good practice to close the connection to the MySQL server. To do this, you can use the mysqli_close function. It takes the connection object ($conn) as a parameter and closes the connection. Make sure to pass the correct connection object to mysqli_close, like mysqli_close($conn), to close the connection properly. Although PHP automatically closes the connection at the end of the script execution, it's recommended to explicitly close the connection when it's no longer needed to free up resources.

In PHP OOP, a class implements an interface using the implements keyword followed by the name of the interface or a comma-separated list of interface names. For example: class ClassName implements InterfaceName { } By implementing an interface, a class agrees to fulfill the contract defined by the interface. The class must provide an implementation for all the methods defined in the interface. A class can implement multiple interfaces by listing them after the implements keyword, separated by commas. This allows the class to define behavior and functionality according to multiple contracts. To know more about interface implementation, visit: http://php.net/manual/en/language.oop5.interfaces.php

To generate a random number in PHP, you can use the rand() function. The rand() function generates a pseudo-random number within a specified range or, if no range is given, between 0 and the maximum random value supported by the system. This function is useful when you need to generate random numbers for various purposes, such as generating random IDs or selecting random elements from an array.

In PHP, you can establish an HTTP connection and fetch the content of a web page using the file_get_contents() function. This function allows you to retrieve the contents of a file or URL and returns the content as a string. By providing a URL as the parameter, you can establish an HTTP connection and fetch the HTML content of a web page. Additionally, you can use this function with various options and stream contexts to handle different scenarios, such as setting HTTP headers or sending POST data. The file_get_contents() function provides a simple way to retrieve web page content in PHP.

To run the interactive PHP shell from the command line interface, you can use the command php -a. This command starts an interactive mode where you can enter and execute PHP code directly. It allows for quick testing and experimentation without the need for a complete PHP script.
