The right formula of: 4 x if & else

I have 4 IF sentences, after that i want to say else(not the condition of any of if) but i get an error.

I have:

if (condition 1) { }
if (condition 2) { }
if (condition 3) { }
if (condition 4) { }

What am i doing wrong ?

if the condition is on the same variable

use switch case

its more clear !

else see Mark Baker answer

if (condition 1) { 
   ...
} elseif (condition 2) { 
   ...
} elseif (condition 3) { 
   ...
} elseif (condition 4) { 
   ...
} else { 
   ...
}

EDIT

The difference is that each of your "if (condition n) { }" statements (except the last) is syntactically complete, terminating with the closing } and therefore your "else { }" is only related to the very last if statement in your list.

if (condition 1) { // Test if condition 1 is met
   ...
} // end of if (condition 1) statement
if (condition 2) { // Test if condition 2 is met regardless of any previous conditions 
   ...
} // end of if (condition 2) statement 
if (condition 3) { // Test if condition 3 is met regardless of any previous conditions  
   ...
} // end of if (condition 3) statement
if (condition 4) {  // Test if condition 4 is met regardless of any previous conditions 
   ...
} else { // will always be executed if (condition 4) is not met, even if conditions 1,2 or 3 have been met
   ...
} // end of if (condition 4) statement

So if condition 1 is met, the code will still check for conditions 2 and 3, then test for condition 4 and execute the else if condition 4 is not met, ecen though condition 1 was met.

Using elseif, the else will only be executed if none of conditions 1, 2, 3 or 4 or met.

IF the conditions are simple id use switch/case:

switch (true) {
  case /* condition 1 */:
    //logic
    break;
  case /* condition 2 */:
    //logic
    break;

  case /* condition 3 */:
    //logic
    break;

  case /* condition 4 */:
    //logic
    break;

  default:
  // essentially your else logic
}

IF your conditions are complext then use elseif as others have mentioned.

How about this:

if (condition 1) { } else if (condition 2) { } else if (condition 3) { } else if (condition 4) { } else { }

or this:

if (condition 1) { }; if (condition 2) { }; if (condition 3) { }; if (condition 4) { } else { }

Depending on what you want :)

i think a switch case pretty much covers the whole thing:

switch($something)
{
   case "val1": do_something();
   break;
   default: do_something_else();
}
