< PHP
If you want to compare one variable to multiple values in PHP, you can do so 2 different ways:
if / elseif
if ($fnord == 23) {
echo "Found a 23!";
} elseif ($fnord == 17) {
echo "Found a 17!";
} elseif ($fnord == "Foobar") {
echo "Fnord is a string!";
} else {
echo "Nothing special";
}
OR you can do the same like this
switch / case
switch ($fnord) { case 23:
echo "Found a 23!"; break;
case 17:
echo "Found a 17!"; break;
case "Foobar":
echo "Fnord is a string!"; break;
default:
echo "Nothing special";
}
read here why you need the "break"
Which is Faster ?
Now, you might wonder, which is "better" to use?
Look at this Benchmark provided by Shai-Tan comparing them.
It turns out that the difference is almost not noticable but switch is a tiny bit faster.
