Which is quicker?

[Decode]

This;


if ( $id == "1" ) {
}
else {
if ( $id == "2" ) {
}
else {
if ( $id == "3" ) {
}
else {
}
}
}
or this;


if ( $id == "1" ) {
}
else if ( $id == "2" ) {
}
else if ( $id == "3" ) {
}
else {
}

Second version, as I think if else's are slower than elseifs.

Surely the best way would be to use switch and cases....



$id = 2;

switch ($id) {
case 1:
echo "ID has the value of 1";
//add query/function/echo etc...
break;
case 2:
echo "ID has the value of 2";
//add query/function/echo etc...
break;
case 3:
echo "ID has the value of 3";
//add query/function/echo etc...
break;
}

That would bring up case 2 as the number of $id is 2....

Hope that helps, seems a more logical way of doing it to me. However from the 2 that you posted, 2 wouldn't be any faster but the better way todo it.

Second one, I'm sure =)

No, they both take the same time. Matt's solution is a lot cleaner code and faster.

Switches are a lot better than 100 else if/if else's.

Note my user tag "$learning::php( "slowly" );" - thus meaning I am learning php slowly. So the switch option would be the best option for me personally, but I may be wrong in terms of it been better, though im 90% sure.

Sadly most of the php coders on this forum won't understand that that's valid php (your usertag).

I'm hoping that you'll stop trying to compete with Caleb over an image upload site.
