To delete a cookie in PHP, you can use the setcookie() function and set the expiration date in the past. This causes the browser to discard the cookie, effectively deleting it. Additional information: http://php.net/manual/en/function.setcookie.php

The correct option is: "Resuming the next iteration of a loop." In PHP, the continue statement is used to skip the remaining code in the current iteration of a loop and move on to the next iteration. It is commonly used when you want to skip certain iterations based on a condition. Learn more: https://www.php.net/manual/en/control-structures.continue.php

The correct option is 2. You can modify global variables using the $GLOBALS superglobal in PHP. The $GLOBALS array provides references to all global variables, allowing you to retrieve their values and modify them directly. By accessing specific elements using their names as keys in the $GLOBALS array, you can update the values of global variables from anywhere within the script. However, it is generally recommended to use caution when modifying global variables, as excessive reliance on them can lead to code complexity and potential issues. It is often preferable to utilize other techniques, such as passing variables as function parameters or using object-oriented design principles, to achieve better code organization and maintainability.

The correct option is 4. Indexed arrays in PHP have several common uses, including storing a collection of user input values, tracking session data for multiple users, and iterating over a list of items. Indexed arrays provide a convenient way to store and retrieve multiple values sequentially. They are often used when the order of elements and easy access by position are important.

In PHP, you can include a file using the require() statement, which includes and evaluates the specified file during runtime. This allows you to reuse code from other files in your current PHP script.

In PHP, to create an object from a class, you would use the new keyword followed by the class name and parentheses. The correct option is "Using the new keyword and the class name." For more information, consult the PHP documentation on creating objects: http://php.net/manual/en/language.oop5.php

The correct option is 1. The $GLOBALS superglobal in PHP is an associative array that contains references to all variables that are currently defined in the global scope of the script. The keys of the $GLOBALS array are the variable names, and the values are references to the corresponding variables. It provides a way to access global variables from anywhere within the script, including within functions or classes, without having to use the global keyword. By accessing the $GLOBALS superglobal, you can retrieve and manipulate global variables as needed. However, it is generally recommended to use global variables sparingly and follow good coding practices to avoid potential issues.

The function func_num_args() is used to retrieve the number of arguments passed to a function in PHP. It is often used in conjunction with other functions like func_get_arg() and func_get_args() to create flexible and dynamic functions that can handle a variable number of arguments. For example, you can use func_num_args() inside a function to determine how many arguments were passed to it and then iterate over the arguments using a loop with func_get_arg() to process each argument individually. The func_num_args() function provides a convenient way to create generic functions that can adapt to different input parameters. It's important to note that func_num_args() can only be used within a user-defined function and not outside of it.

This statement is false. The is_float() function in PHP checks if a variable is a float, not an integer. It returns true if the variable is a float (a number with a decimal point or an exponential form) and false otherwise. To check if a variable is an integer, you can use the is_int() function.

The filter_list() function is used to get the list of all supported filters in PHP. It returns an array containing the names of all available filters. Learn more at: http://php.net/manual/en/function.filter-list.php
