Question 1

Include statements support only absolute path notation.

Accepted Answer

Include statements in programming languages like PHP can support both absolute and relative path notations to reference files.

Question 2

The primary use of the include and require statements is to reuse content on multiple web pages by allowing you to insert the content of an external file, called an include file, in your PHP scripts.

Accepted Answer

This is a correct statement about the primary use of include and require statements in PHP.

Question 3

One of the primary differences between the while statement and the for statement is that in addition to a conditional expression, the for statement can also include code that initializes a counter and changes its value with each iteration.

Accepted Answer

This is correct. The for statement typically includes three expressions in its parentheses, separated by semicolons: an initialization expression, a conditional expression, and an update expression. The initialization expression is executed only once, before the loop starts. The conditional expression is evaluated before each iteration of the loop, just like with the while statement. The update expression is executed after each iteration of the loop. The for statement is often used with a loop counter variable, which is initialized in the initialization expression and updated in the update expression.

Question 4

A command block is a group of statements within a set of opening and closing ____.
A) brackets
B) braces
C) parentheses
D) quotation marks

Accepted Answer

Command blocks use braces to indicate the beginning and end of a group of statements.

Question 5

A(n) ____ statement is a control structure that repeatedly executes a statement or series of statements while a specific condition is TRUE or until a specific condition becomes TRUE.
A) repeat
B) replicate
C) loop
D) circular

Accepted Answer

A loop statement is used to repeatedly execute a set of statements until a specific condition is met. The condition is checked at the beginning of the loop, and if it is true, the statements inside the loop are executed. After the statements are executed, the condition is checked again, and if it is still true, the statements are executed again. This process continues until the condition becomes false. The most common types of loop statements are the for loop, while loop, and do-while loop.

Question 6

When one decision-making statement is contained within another decision-making statement it is referred to as a ____ decision-making structure.
A) enclosed
B) contained
C) nested
D) layered

Accepted Answer

When one decision-making statement is placed inside another decision-making statement, it is called a nested decision-making structure. This helps to organize and streamline complex decision-making processes by breaking them down into smaller, more manageable steps. Therefore, the best choice is C - nested.

Question 7

You can use the terminate statement to halt a looping statement and restart the loop with a new iteration.

Accepted Answer

The correct statement to halt a looping statement and restart the loop with a new iteration is "continue", not "terminate". "Terminate" is not a standard programming keyword for controlling loops.

Question 8

With many programming languages, global variables are automatically available to all parts of your program, including ____.
A) statements
B) definitions
C) functions
D) declarations

Accepted Answer

Global variables are automatically available to all functions in the program.

Question 9

What will be returned if you use a local variable outside the function in which it is declared?
A) value
B) error message
C) function
D) nothing

Accepted Answer

If you use a local variable outside the function in which it is declared, it will result in an error message as the variable has not been defined in the global scope.

Question 10

When you declare a global variable with the global keyword, you do not need to assign the variable a(n) ____.
A) value
B) definition
C) function
D) name

Accepted Answer

When declaring a global variable with the global keyword, you do not need to assign a value to the variable, as it will default to None until a value is assigned to it elsewhere in the program.

Question 11

When you use a variable in a PHP program, you must be aware of the variable's ____.
A) placement
B) scope
C) function
D) statement

Accepted Answer

The scope refers to where in the program the variable can be accessed. It's important to know because trying to access a variable outside of its scope can result in errors or unexpected behavior in the program.

Question 12

Which of the following terms is not associated with the switch statement? A) switch title B) case label C) executable statements D) break keyword

Accepted Answer

The term "switch title" is not associated with the switch statement. The correct term is "switch expression" or "switch variable," which is the value that is being tested in the switch statement.

Question 13

The statements in a do...while statement always execute repeatedly before the conditional expression evaluates the count variable.

Accepted Answer

In a do...while loop, the statements within the loop execute once before the conditional expression is evaluated.

Question 14

The include statement and the require statement perform the same function and can be used interchangeably.

Accepted Answer

While both the include and require statement allow you to include external files in your PHP code, they function slightly differently. The include statement will continue to execute the code even if the file being included cannot be found or is invalid. The require statement, on the other hand, will stop the script and produce a fatal error if the file being required cannot be found or is invalid. Therefore, they cannot be used interchangeably in all situations.

Question 15

The parameters within the parentheses of a function declaration are what kind of variables?
A) local
B) global
C) unknown
D) declared

Accepted Answer

The parameters within the parentheses of a function declaration are local variables, meaning they only exist and can be accessed within the scope of the function.

Question 16

You will not receive an error if you attempt to use a foreach statement with any variable types other than arrays.

Accepted Answer

The foreach statement is designed to iterate over collections that implement the IEnumerable or IEnumerable interface, not just arrays. This includes many types such as lists, dictionaries, and other collection types, not only arrays.

Question 17

The for statement performs essentially the same function as the while statement.

Accepted Answer

The for statement is a control flow statement that is used to execute a block of code repeatedly for a fixed number of times. It is often used when we already know the number of times the loop needs to be executed. The while statement, on the other hand, is used when we need to repeat a block of code until a certain condition is true. They have similar functions, but the for statement is specifically designed for a fixed number of iterations.

Question 18

The do...while statement executes a statement or statements once, then repeats the execution as long as a given conditional expression evaluates to TRUE.

Accepted Answer

The given statement is true. In a do...while loop, the statement is executed at least once before checking the condition for further execution.

Question 19

A variable's scope can be either global or ____.
A) local
B) undeclared
C) universal
D) declared

Accepted Answer

When a variable is declared within a function or block of code, it has local scope, meaning it can only be accessed within that function or block of code. If a variable is declared outside of any functions or blocks of code, it has global scope, meaning it can be accessed from anywhere within the code. So, the missing option is local.

Question 20

The for...while statement is used to iterate or loop through the elements in an array.

Accepted Answer

The correct statement is "for...of" statement is used to iterate or loop through the elements in an array.
