To prevent this add a break statement to the end of each case block. ![]() In many occasions, you may want to compare the same variable (or expression). This Example For variable not match so print is default The switch statement is similar to a series of IF statements on the same expression. This Example for different case to same Statements statement by statement) and once PHP finds a case statement that evaluates to true, it’s not only executes the code corresponding to that case statement, but also executes all the subsequent case statements till the end of the switch block automatically. The switch statement executes line by line (i.e. The switch-case statement is an alternative to the if-elseif-else statement, which does almost the same thing. The switch-case statement differs from the if-elseif-else statement in one important way. Switch case in PHP are control structures that allow the programmer to execute different blocks of code based on the value of a variable or expression. Syntax:-Ĭonsider the following example, which displays a different message for each day. The switch-case statement tests a variable against a series of values until it finds a match, and then executes the block of code corresponding to that match. ![]() The switch-case statement is an alternative to the if-elseif-else statement, which does almost the same thing. There's no need to preemptively save the result in a variable either.Check Several Possible constant values for an expression. Without having to worry about the function being re-evaluated for every case. I think this fact needs a little bit more attention, so here's an example: 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. PHP Switch statement is a conditional statement, which is used to choose one of the action to perform from the multiple actions, relative to the true condition. ![]() This is listed in the documentation above, but it's a bit tucked away between the paragraphs.
