Are you looking for a code example or an answer to a question « ARITHMETIC OPERATIONS DEMO USING SWITCH CASE IN PHP » Examples from various sources (github,stackoverflow. Here we can see that program stops the execution of other case statements due to the break statement in matched case. We need to use the break statement to avoid this. Here we can see that, after the match case found ( in this case 1 ) all other case codes also executed. See the difference in ouput for the following two sample programs After that it will execute all other case codes till a break statement found.Its really important to understand this behavior to avoid mistakes with this statement.īreak statement is used if we want to stop the execution of other cases when one case match with our condition. No code will execute till the first match case found. Switch statements is executed by line by line. Operation statements when there is no match in all the above cases See the syntax structure of switch case statement in a PHP program Switch statement is coming for this requirement. If the expression equals a value in a case, e.g. In many situations we need to compare a variable against different values and needs different operations according the values. The switch statement compares an expression with the value in each case. Its a best alternative for elseif statements using the same expression. ![]() No break is needed in the default case.PHP Switch case statement is an alternative for complex IF statements with a same expression. The default case can be used for performing a task when none of the cases is true. If no break appears, the flow of control will fall through to subsequent cases until a break is reached.Ī switch statement can have an optional default case, which must appear at the end of the switch. When a break statement is reached, the switch terminates, and the flow of control jumps to the next line following the switch statement. When the variable being switched on is equal to a case, the statements following that case will execute until a break statement is reached. Read more about the switch conditional in our PHP switch Statement Tutorial. The constant-expression for a case must be the same data type as the variable in the switch, and it must be a constant or a literal. The case keyword is used to jump to a line of code when an expression has a specific value in a switch conditional. Each case is followed by the value to be compared to and a colon. You can have any number of case statements within a switch. ![]() The expression used in a switch statement must have an integral or enumerated type, or be of a class type in which the class has a single conversion function to an integral or enumerated type. Here, the found variable is used to check the variable bookname matches with any case value or not. The following rules apply to a switch statement − Example-1: Simple use of switch.case statement Create a PHP file with the following script to check the simple use of the ‘ switch ’ statement. * you can have any number of case statements */ The syntax for a switch statement in C programming language is as follows − Each value is called a case, and the variable being switched on is checked for each switch case. A switch statement allows a variable to be tested for equality against a list of values. ![]()
