Alternate Versions of the IF Statement

[cyberRobot]

Is there an alternative form of the if statement that I can use for validation?

 

What I want to do is to shorten code that looks like this:

if($memType!='Regular' && $memType!='Student' && $memType!='Retired') {
//invalid membership type, display error
}

 

Is there any way to rewrite the if statement so that I don't need to repeat $memType?

 

 

In the past, I've used a switch statement:

switch($memType) {
case 'Regular':
case 'Student':
case 'Retired':
	//do nothing

default:
	//invalid membership type, display error
}

 

...but I feel a little weird using switch for this scenario.

 

 

I would also like to avoid using regular expressions since that seems like overkill.

You could use in_array() ..

 

if (!in_array($memType, array('Regular', 'Student', 'Retired'))) {

in_array is one way:

 

$isin=array("Regular", "Student", "Retired);

if(!in_array($memType, $isin)){
//invalid!
}

Awesome, using an array is so much cleaner than the if version! 

 

Thanks
