When PHP Switch case checks the condition then it jumps to the appropriate case, skipping all other cases before that, and executes it. There's no need to preemptively save the result in a variable either. PHP Switch Case uses 'case', each case has a different set of instructions associated with it, written by the programmer. There many cases that contain some blocks. Without having to worry about the function being re-evaluated for every case. PHP Switch case statement perform a test and execute a piece of code if it finds the exact match of the test result. I think this fact needs a little bit more attention, so here's an example: Since PHP executes the switch statement from the matching case label till it encounters the break statement, you can combine several cases in one. The difference between a series of if statements and the switch statement is that the expression you're comparing with, is evaluated only once in a switch statement. In many occasions, you may want to compare the same variable (or expression). Switch statements are similar to a series. This is listed in the documentation above, but it's a bit tucked away between the paragraphs. The switch statement is similar to a series of IF statements on the same expression.
