You can use the $_POST superglobal in PHP to get data sent in the URL's query string.
- TRUE
- FALSE
The statement is false. The $_POST superglobal is specifically used to collect form data submitted via the POST method, and it does not retrieve data from the URL's query string. To access data in the query string, the $_GET superglobal is used. The $_GET superglobal retrieves data sent in the URL's query string using the GET method.

In PHP, to handle a form, you can use the $_POST or $_GET superglobal to access the data, where the method used depends on the ______ attribute of the form element in the HTML.
- Action
- Method
- Input
- Name
In PHP, to handle a form, you can use the $_POST or $_GET superglobal to access the data submitted through the form. The method used depends on the method attribute of the form element in the HTML. The method attribute specifies how the form data is sent to the server, either using the HTTP POST method ($_POST) or the HTTP GET method ($_GET). In PHP, you can access the form data using the corresponding superglobal ($_POST or $_GET) based on the method specified in the form's method attribute. This allows you to retrieve the form input values and perform necessary actions based on the submitted data. Learn more: https://www.php.net/manual/en/tutorial.forms.php
In PHP, a number with a decimal point or an exponential form is considered a float.
- TRUE
- FALSE
This statement is true. In PHP, a number with a decimal point (e.g., 3.14) or in exponential form (e.g., 1.2e3) is considered a float. Floats, also known as floating-point numbers or doubles, represent real numbers with decimal points. Integers, on the other hand, do not contain decimal points.

You have a function in your PHP script that's supposed to return a value, but it's not returning as expected. How would you debug this?
- Enable error reporting in PHP settings.
- Check for syntax errors in the function.
- Add debugging statements like var_dump() or echo within the function.
- Ensure the function is properly called and any necessary input arguments are provided.
To debug a function that's not returning the expected value, you can add debugging statements like var_dump() or echo within the function to check the intermediate values and flow. You should also ensure that the function is properly called, and any required input arguments are provided. Additionally, enabling error reporting in PHP settings can help identify any syntax or runtime errors. Learn more: https://www.php.net/manual/en/functions.debugging.php
A PHP class can have more than one constructor.
- No
- Yes
- Depends on the PHP version
- Only if the class is abstract
In PHP, a class cannot have more than one constructor. The correct option is "No." Unlike some other programming languages, PHP does not support multiple constructors within a single class. However, you can achieve similar functionality by using optional parameters or method overloading. For further details, refer to the PHP documentation on constructors: http://php.net/manual/en/language.oop5.decon.php
You are writing a PHP script and you need to collect form data, but you don't know if the data was sent using the GET or the POST method. How would you do this using the $_REQUEST superglobal?
- Check if the $_REQUEST variable is empty to determine the method.
- Use the isset() function on the $_REQUEST['method'] key.
- Use the $_SERVER['REQUEST_METHOD'] variable to determine the method.
- Use the $_GET and $_POST superglobals separately to handle each method.
To collect form data when you are unsure of the method used (GET or POST), you can use the $_REQUEST superglobal. The $_REQUEST superglobal combines the values of both GET and POST requests. To determine the method, you can use the $_SERVER['REQUEST_METHOD'] variable, which holds the HTTP request method used to access the page. If it contains the value 'GET', the data was sent using the GET method. If it contains 'POST', the data was sent using the POST method.

The PHP files should be saved with a ______ extension for the server to parse them.
- .html
- .js
- .php
- .py
PHP files should be saved with a .php extension. The PHP interpreter processes files with this extension, executing any PHP code contained within and sending the resulting output (usually HTML) to the client's browser. Learn more: https://www.php.net/manual/en/tutorial.firstpage.php
Which of the following are ways to upload a file in PHP?
- Using an HTML form with the enctype attribute set to "multipart/form-data" and an input element of type "file"
- Using the upload() function in PHP
- Using the file_get_contents() function to read the file contents and process them
- Using the include() function to include the file in the PHP script
In PHP, one of the ways to upload a file is by using an HTML form with the enctype attribute set to "multipart/form-data" and an input element of type "file". This allows the user to select a file to upload from their local system. This file will then be sent to the server for processing. The other options mentioned are not valid methods for file upload in PHP.
What does accessing a class via :: mean?
- Static access
- Dynamic access
- Private access
- Protected access
Accessing a class via :: represents static access, allowing you to access static properties or invoke static methods of a class. Learn more: http://php.net/manual/en/language.oop5.static.php
To access a global variable inside a function using $GLOBALS, you can use $GLOBALS['variable_name'] where 'variable_name' is the name of the ______.
- Global variable
- Local variable
- Function
- Class variable
The correct option is 1. To access a global variable inside a function using $GLOBALS, you can use $GLOBALS['variable_name'], where 'variable_name' is the name of the global variable you want to access. By referencing the variable name as a key in the $GLOBALS array, you can retrieve the value of the global variable from within the function. This allows you to access global variables without the need for the global keyword, which is required to access global variables within the function's local scope. However, it is generally recommended to use global variables sparingly and consider passing variables as parameters or using object-oriented design principles for better code organization and maintainability.
