A function statement is a block where the function is declared and defined.

y = x2
Of course it is possible to call a PHP-function inside an echo statement. The function will be executed and returns a value. This value then is used in the echo statement. For example: echo "Ferengi-Rule #1: ", ferengi_rule(1), "\n"; echo "Random: ", ferengi_rule(0), "\n"; function ferengi_rule($number) { $rules = array( 1 => "Once you have their money, never give it back.", 2 => "You can't cheat an honest customer, but it never hurts to try.", 3 => "Never buy anything for more than is absolutely necessary.", 4 => "Sex and profit are the two things that never last long enough." // ... ); if( isset($rules[$number]) ) { return $rules[$number]; } else { return array_rand($rules); } }
Finding the final cost of an item that originally sold for x dollars but is marked down 40% and has an 8.25% tax rate.
In a declarative statement, you initialize the object. But in an imperative statement, you use a preexisting statement and use it.

IF function
IF, in C and C++, is not a function - it is a statement. There are two parameters... if (expression) statement; The expression is evaluated. If it has logical result true, or arithmentic result not zero, the statement is executed; if not, the statement is not executed. The statement can be a single statement, in which it is terminated with a semi-colon, or it can be a block of statements, in which it is surrounded by braces.
Statements are composed from expressions. A semi-colon turns an expression into a statement. A function is not a statement it is a type definition. A statement block is a compound statement, one or more statements delimited by braces, {}. A function block is the body of a function. The body must be enclosed in braces, {}.
it's not a statement, it's a function: len= printf (format, ...more-parameters...);
statement should not return a value but function returns a value
All usable statements in PHP can cause a function to be executed - however, that's not to say that every statement will execute a function. A statement is defined by the programmer, who it is ultimately the one responsible for including a function, more than one function, or no functions.
The multi-step income statement is classified by function, and the single-step income statement is classified by behavior.
return;orreturn ;PS: not function, statement!
In a value-returning function, you need to include a "return" statement to specify the value that the function should return back to the caller.
Which statement describes the rate of change of the following function?f(x) = -6x - 9
The statement that causes a function to end and sends a value back to the calling part of the program is the return statement. When a return statement is executed, it terminates the function and can optionally pass a value back to the caller. If no value is specified, the function returns None in Python or equivalent in other languages. This allows the caller to receive the result of the function's computation.
