![]() Note: Beginning programmers should always include the break to avoid any unnecessary confusion. If there is a match, the block of code associated with that case is. The form of the switch statement is rather unique, so spend some time reviewing it before moving on. The value of the expression is then compared with the values for each case in the structure. So when the Switch case is activated then it looks for variables and searches for the right case. The value of $destination was Tokyo so it is simply printing case “Tokyo”. PHP Switch Statement Example $destination = "Tokyo" Įcho "Bring 15 bottles of SPF 50 Sunscreen" If no case matches with the expression the default code block will be executed. However, if exp1 doesn’t matches with expression then exp2 will be compared and comparisons will be continued until the matching case. When exp1 matches the expression code block 1 will be executed and the break statement will cause an exit from the switch statement and no further comparison will be done. The switch statement is useful when you need to test a single variable against a series of exact integer (including int, byte, and short types), character, or. ![]() For example, in the above structure, the expression is compared with all the case values. PHP switch statement tests the value of an expression against a list of case values successively. Structure of PHP switch case switch(expression)Ĭase exp1: //note that instead of semi-colon a colon is used PHP switch statement is used to avoid long blocks of if.elseif.else code. However, there are times when a switch statement is more convenient so if statement is not the most efficient way to check for certain conditions. In an elseif statement, the condition is. In the previous lesson, we covered the various elements that make up an If Statement in PHP. In a switch statement, the condition is evaluated only once and the result is compared to each case statement. PHP Switch Case Statement compares the same variable or expression with many values and executes the different blocks of codes depending on the condition. It tests one variable against multiple conditions and executes the block whose condition is met. How to apply 'or' without using break keyword In the example below, we demonstrate a switch case on how to apply or without using the break keyword. PHP switch case allows us to make a decision from numerous choices or expressions. Here, we will show you two ways of using the or operator in switch cases in PHP. ![]()
