switch()

[Anon]

Doing my best to explain this:

If I have my index.php with a switch() statement of 5 different cases, is there a way to make index.php default to:

index.php?function=default

I have been trying for a few hours ot figure this out and read over a couple of books, but nothing seems to answer this quesiton.

Anyone that can help?

You could just use the default option.

switch ($i) {
case 0:
print "i equals 0";
break;
case 1:
print "i equals 1";
break;
case 2:
print "i equals 2";
break;
default:
print "i is not equal to 0, 1 or 2";
}

Thats kind of what i was asking... scenario:

<?
echo "\n<all the beginning html crud>\n";

switch ($funtion) {
case 0:
print "This is Case 0";
break;
case 1:
print "This is Case 1";
break;
case 2:
print "This is Case 2";
break;
default:
print "Welcome to our page, please choose a case";
}

echo "

?>

Will this by default show my page and give me the default case and say "Welcome to our page, please choose a case! .. that is my question 🙂

In a word yes. if the switch cant match any of the case statements then the default will be used. So if in your example $function was 7 the default case would be used.

I could be wrong, but from what "I" understand it walks through the case..

so maybe if i put default up top it will just walk right into it?

[khaine]

It does walk though the case but it should only execute the code for the case that it matches. so no match no execution.
