Php switch case equals two values8/2/2023 ![]() If the value of the variable matches a case, the corresponding code block is executed, and the program flow exits the switch statement. The flowchart of a switch statement in PHP begins with the decision-making process, where the value of a variable is compared to a series of possible values or expressions. Flowchart of Switch StatementĪs you know that a flowchart is a diagrammatic representation of a program's logic that shows how data flows from one process to another. This can be particularly useful for handling unexpected or unknown input. The switch case in PHP can also include a default case that is executed if none of the other cases match. If a match is found, the corresponding block of code is executed. ![]() Instead, the switch statement evaluates a single expression and compares its value to a set of predefined cases. ![]() Switch case in PHP provides an alternative to multiple if-else statements that can be difficult to read and maintain. This can be particularly useful when dealing with complex conditional statements or when multiple conditions must be evaluated. 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. The basic syntax of a switch statement in PHP involves the use of the switch keyword followed by an expression in parentheses. The switch statement provides an alternative to using multiple if-else statements, which can become cumbersome and difficult to read as the number of conditions increases. There's no need to preemptively save the result in a variable either.Switch case in PHP is a control structure that allows the program to compare a single expression against multiple values and execute different code blocks depending on which value matches the 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. This is listed in the documentation above, but it's a bit tucked away between the paragraphs.
