![]() It determines what is to be done if none of the cases are true. The "default:" portion of the switch statement is similar to the else clause used with if statements. ![]() The value of the expression is compared with the values of eachcCase. It does the same thing as if-elseif-else statement. PHP continues to execute the statements until the end of the switch block, or the first time it sees a break statement. Each block ends with a break to indicate that the remainder of the switch statement should be skipped after the case is true and the associated block of code is run. The switch-case statement is an alternative to the if-elseif-else statement. Only when a case statement is found with a value that matches the value of the switch expression does PHP begin to execute the statements. The switch statement accepts multiple lines of code in each block of code following each case, however our example only has a single line of code that should be run in the event that the case (condition) is true. in CodeExampler Php Switch If the expression equals a worth during a case, e.g., value1, PHP executes the code block within the matching case until it. That value is compared against multiple cases, each of which contain their own value and end with a full colon rather than the standard semi-colon. In our example, we begin by providing the switch statement with a value in the form of a variable. When the case, or condition, is met (true), the specified block of code is executed, and the remainder of the switch statement is skipped. The switch statement begins by accepting a single value, which it compares against multiple cases. PHP Switch Statement: Default Case You may have noticed the lack of a place for code when the variable doesnt match our condition. What You Can Do with PHP There are lot more things you can do with PHP. If youre a beginner, start with the basics and gradually move forward by learning a little bit every day. 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 can replace multiple if/elseif/elseif statements when you want to determine whether or not one value is equal to one of many other values in a more efficient manner. Tip: Our PHP tutorial will help you to learn the fundamentals of the PHP scripting language, from the basic to advanced topics step-by-step. The switch statement executes line by line (i.e. Sometimes, multiple if/elseif/elseif statements are just not the most efficient option when checking for a specific condition.
