PHP return Statement


PHP return statement immediately terminates the execution of a function when it is called from within that function.

This function is also used to terminate the execution of an eval() function or script file.

If this function is called from a global scope, the function stops the execution of the current script. If the current script file was included using include() or required(), then control goes back to the calling file.


return expression 

Where expression is any valid expression. Note that, since the return is not a function but a language construct, using parenthesis is not required.

PHP: Tips of the Day

In PHP, there are two versions of logical AND and OR operators.

Operator True if
$a and $b Both $a and $b are true
$a && $b Both $a and $b are true
$a or $b Either $a or $b is true
$a || $b Either $a or $b is true

Note that the && and || opererators have higher precedence than and and or. See table below:

Evaluation Result of $e Evaluated as
$e = false || true True $e = (false || true)
$e = false or true False ($e = false) or true

Because of this it's safer to use && and || instead of and and or.
