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.
Where expression is any valid expression. Note that, since the return is not a function but a language construct, using parenthesis is not required.
|If called from within a function||Returns the argument of the function.|
|If the current script file was included using include() or required()||Value given to return().|
|If no parameter is supplied||NULL is returned.|
Code of p.php
<?php include("q.php"); echo "p"; ?>
Code of q.php
<?php echo "q"; return; ?>
PHP: Tips of the Day
In PHP, there are two versions of logical AND and OR operators.
|$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.
