function myPrice($price){
switch (true) {
case ($price > 100) :
echo '$price = ', $price, '<br />';
echo "Price is $100 up.";
break;
case (($price > 50) || ($price =50)):
echo '$price = ', $price, '<br />';
echo "Price is $50 and up.";
break;
case ($price >25):
echo "Price is $25 up.";
break;
default:
echo "Price is no more then $25.";
break;
}
}
When parameter $price is less than 50, for example 30, execute
myPrice(30),
actual result always is:
$price = 50
Price is $50 and up.

You need to replace switch($price) by switch(true) so that the first
case with an
expression evaluated to true will be executed.

($price > 100) is false.
false is 0, then case is executed.

echo "Prince is no more then $25.";
break;
}
