Handling Your Data with Operators
There are many operators in PHP, and most of them do the same thing they do in JavaScript. Following is a list of the PHP operators:
-
new
-
[
-
!~++--
-
*/%
-
+-.
-
== !=
-
&
-
|
-
&&
-
||
-
?:
-
=+=-=*=/=.=%=&=|=^=<<=>>=
The example, operators.php, puts some of these operators to work:
<html> <head> <title> Using PHP operators </title> </head> <body> <h1> Using PHP operators </h1> <? echo "4 + 6 = ", 4 + 6, "<br>"; echo "4 - 6 = ", 4 - 6, "<br>"; echo "4 * 6 = ", 4 * 6, "<br>"; echo "4 / 6 = ", 4 / 6, "<br>"; ?> </body> </html>
The results of operators.php are shown in Figure 12.9, where you can see that the PHP operators have done what they should.
