Adding Information from a Database 13

Why does the if statement have two equal signs?

PHP uses a double equal sign to test for equality,

and a single equal sign to assign a value to a

variable. Thus, $x = 10 sets the value of the

variable $x to 10 , whereas $x == 10 compares

the value of $x to 10.

Can I test on more than one condition?

Yes. PHP supports the use of if else statements,

which are placed between an if and an else. The

if else statement, like if, takes an expression

as its argument.
