<?php
switch ($i) {
case 'a':
echo "i equals a";
break;
case 'b':
echo "i equals b";
break;
case 'c':
echo "i equals c";
break;
default:
echo "i is not equal to a, b or c";
}
?>
Yes, it is true. Be careful if the compared variable === true!
Because: IT WILL "convert" any unempty string to true AND it will go directly to the
FIST case and print "i equals a" in that example !!!
How non-sens-making behavior! At first I thought it is a bug. :)
If I could I would definitely change this nonsense-behavior in case of true! (for example by
converting it internally to number 1). But I am not requesting it - I know it is not possible
here...
Just wanted to say:
People, Be extra careful not to get true dropped into a switch! :-)
