The block of code in a PHP do...while loop will execute at a minimum of once. This is because the code block is executed before the condition is checked. Even if the condition evaluates to false, the code block has already executed once. The do...while loop ensures that the code block is executed at least once, and then the condition is evaluated to determine if further iterations are needed. If the condition is true, the loop will execute the block of code again. If the condition is false, the loop terminates. Learn more: https://www.php.net/manual/en/control-structures.do.while.php

The round() function in PHP rounds a floating-point number to the nearest decimal place. The number is rounded to the specified precision or, by default, to the nearest whole number. The rounding behavior follows the standard rounding rules. This function is useful when you need to round a floating-point number to a specific decimal place or to the nearest whole number.

All of the given options are true about strings in PHP. Strings can be concatenated using the dot (.) operator to join multiple strings together. Strings enclosed in double quotes ("") allow for variable interpolation, where variables can be directly included within the string. Additionally, strings in PHP can be accessed using array-like indexing, allowing you to access individual characters by their position.

To process data sent in the URL's query string in PHP using the $_GET superglobal, you can access the data using the $_GET['key'] syntax, where 'key' represents the name of the parameter in the query string. Once accessed, you can process the data according to your requirements in the PHP script. This can include tasks such as filtering, validating, or performing specific actions based on the data passed through the URL. Learn more: https://www.php.net/manual/en/reserved.variables.get.php

To use the $_SERVER superglobal in PHP, you can directly access the desired element in the $_SERVER array using its key. For example, to access the current script filename, you can use $_SERVER['PHP_SELF']. The $_SERVER array is available in the global scope, and its elements can be accessed throughout your PHP script.

PHP supports two types of numbers: integers and floats. Integers represent whole numbers without decimal points, while floats, also known as floating-point numbers or doubles, represent real numbers with decimal points. These two number types provide different representations for different kinds of numeric data in PHP.

In PHP, the if statement is used to execute some code if a condition is true. The condition is a logical expression that evaluates to either true or false. If the condition is true, the code block associated with the if statement is executed. If the condition is false, the code block is skipped. The if statement allows you to control the flow of execution based on the evaluation of a specific condition. Learn more: https://www.php.net/manual/en/control-structures.if.php

To access data sent via the GET method from a form in PHP using the $_GET superglobal, you can directly use the $_GET superglobal to access the data. When a form is submitted using the GET method, the form data is appended to the URL's query string, and you can retrieve it using $_GET['key'] syntax, where 'key' represents the name of the input field in the form. Using $_GET allows you to access the data without needing to use $_POST or $_REQUEST superglobals. Learn more: https://www.php.net/manual/en/reserved.variables.get.php

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 $_GET superglobal to access the data submitted through the form. The method used depends on the method attribute of the form element in the HTML. The method attribute specifies how the form data is sent to the server, either using the HTTP POST method ($_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
