Answer 1

We have 14 Language Construct:

Assert: Debug command to test a condition and do something if it is not true.

echo: Outputting a value to stdout.

print: Outputting a value to stdout.

Exit: Optionally outputting a message and terminating the program.

Die: This is an alias for the exit.

Return: Terminates a function and returns control to the calling scope, or if called in the global scope, terminates the program.

include: Includes a file and evaluates it. PHP will issue a warning if the file is not found or cannot be read.

include_once: If you specify include_once then PHP will make sure that it includes the file only once.

require: PHP will include a file and evaluate it. If the file is not found or cannot be read, then a fatal error will be generated.

Require_once: If you specify require_once then PHP will make sure that it includes the file only once, but a fatal error will be generated instead of a warning.

Eval: The argument is evaluated as PHP and affects the calling scope.

Empty: Returns a Boolean value depending on whether the variable is empty or not.
Empty variables include null variables, empty strings, arrays with no elements, numeric values of 0, a string value of 0, and Boolean values of false.

isset: Returns true if the variable has been set and false otherwise. unset Clears a variable.

list: Assigns multiple variables at one time from an array.
