A variable declared within a function in PHP has a local scope. It means that the variable is only accessible within that specific function. It cannot be accessed outside of the function or in other functions. This helps in encapsulation and prevents naming conflicts with other variables in different functions.

In PHP, statements end with a semicolon (;). The semicolon is a statement separator, allowing you to put multiple statements on the same line if desired. It's also necessary to end a statement before starting a new line with a new statement. Learn more: https://www.php.net/manual/en/language.basic-syntax.instruction-separation.php

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

In PHP, $_ENV is an array that contains the values of environment variables passed to the script. It provides access to environment-specific information. Learn more: http://php.net/manual/en/reserved.variables.environment.php

The correct option is 1. In PHP, the $GLOBALS superglobal is an associative array that contains references to all global variables that are currently defined in the global scope of the script. It provides a way to access and manipulate these global variables from anywhere within the script. The keys of the $GLOBALS array correspond to the variable names, and the values are references to the corresponding variables. By accessing specific elements using their names as keys in the $GLOBALS array, you can retrieve or modify the values of global variables. It is important to note that using global variables extensively can lead to code complexity and potential issues, so it is recommended to use them judiciously and consider alternative approaches for better code organization and maintainability.

The if statement in PHP can test multiple conditions. You can use logical operators such as && (AND) and

This statement is true. In PHP, a string can contain letters, numbers, special characters, and even control characters. It is a versatile data type used for storing and manipulating text or sequences of characters. Strings can be enclosed in single quotes (''), double quotes ("") or heredoc/nowdoc syntax.

In PHP, a boolean data type can hold one of two values: true or false. Boolean values are used to represent logical states and are often used in conditional statements or to indicate the success or failure of an operation. The value true represents a true or positive condition, while the value false represents a false or negative condition. Learn more: https://www.php.net/manual/en/language.types.boolean.php

The statement is false. The $_GET superglobal is specifically used to retrieve data sent via the GET method, not the POST method. To access data sent via the POST method from a form, you would use the $_POST superglobal. The $_GET superglobal retrieves data from the URL's query string, whereas the $_POST superglobal retrieves data sent through an HTML form using the POST method.

The json_encode() function in PHP is used to encode a PHP object or array into a JSON string. JSON is a popular data interchange format, and this function allows you to convert PHP data into a JSON format that can be easily transmitted or stored.
