The switch-case statement condition its tests a variable against a series of values until it finds a match, after that executes the block of code corresponding to that match. But in the switch statement, you match the result with some predefined values arranged sequentially in cases. Here, The switch-case statement is an alternative method to the if-elseif-else statement or Condition, which are the almost same thing. PHP if statement evaluates the condition and the result if true and if the result is true it executes the code. Difference between PHP switch case and PHP if elseif If you do not add the break statement, the output will execute both the matched case code and the block of code inside the default statement. The example contains a variable $result which will not match with any cases and because of this, the block of code inside the default statement will get executed.ĭon’t forget to add the break statement after each case.
