If a break statement is not included, all subsequent case statements will be executed, even if they don't match the value of the variable or expression being evaluated. Each case statement should end with a break statement to prevent execution from continuing into the next case statement.Important Points to Be Noticed About Switch Case This is then followed by a set of curly braces containing a series of case statements, each with a value or expression to compare against the variable or expression in the switch statement. The switch case in php syntax starts with the switch keyword, followed by a pair of parentheses containing the variable or expression being evaluated. If none of the cases match, the program flow moves to the default case, represented by a rectangular symbol with a label indicating that it is the default case. The program flow moves to the code block associated with the matching case, and execution stops when a break statement is encountered. The cases are represented by rectangular symbols branching off from the diamond symbol, each with a label indicating the value or expression being compared. The flowchart of a switch case in PHP shows the decision-making process as a diamond-shaped symbol with the variable or expression is evaluated at the top. 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. 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.
