Design Pattern

[RobertP]

This is quite simple, however i would like your opinions...

 

When should i use switch instead of ifelse ?

 

after 2 or more possibilities?

5 or more?

 

Currently i am using this for the most simplistic design:

else if($command=='content'&&count($commands)>0){
$content = 'n/a';
if($commands[0]=='dashboard'){
	$content = 'Dashboard';
}
elseif($commands[0]=='settings'&&isset($commands[1])){
	if($commands[1]=='general'){
		$content = 'Configuration Settings = General Settings';
	}
	elseif($commands[1]=='server'){
		$content = 'Configuration Settings = Server Settings';
	}
	elseif($commands[1]=='member'){
		$content = 'Configuration Settings = Member Settings';
	}
	elseif($commands[1]=='page'){
		$content = 'Configuration Settings = Page Settings';
	}
	elseif($commands[1]=='plugin'){
		$content = 'Configuration Settings = Plugin Settings';
	}
	elseif($commands[1]=='file'){
		$content = 'Configuration Settings = File Settings';
	}
}
styler::validExit($content);
}

 

now i think i should switch to 'switch' statements; but this is just the beginning.

 

ps: this is the core of my administration panel for my cms.

I usually use switch when I have more than 2 cases.

 

I think it is more of a preference thing and what you think is easier to read. I've seen some benchmarks where switch is faster and I've seen some where if/else is faster. This tells me there isn't a huge performance difference, so use whatever you like more.
