#Php if else inside switch statement code
It does not only execute the code corresponding to that case statement but also executes all the subsequent statements case until the end of the switch block automatically. statement by statement) and once PHP finds a case statement that evaluates to true. The switch statement executes line by line (i.e. The PHP Switch Case Statement differs from the if-elseif-else statement in one important way. In the following example $xint is equal to 3, therefore switch statement executes the third echo statement Output: This is case No 3. PHP will execute code block in that case construct and ends the switch statement because of the break statement. If the value of the variable match a value in a case construct. It is very important to understand that the switch statement is executed statement by statement, therefore, the order of case constructs is very important. Third, the break statement is used in each case or default construct to exit the entire switch statement.If the value of the variable or expression does not match any value, the code block in the default construct will execute.In case the value of the variable or expression matches the value in a case construct, the code block in the corresponding case construct will execute.Second, inside the curly braces are multiple case constructs where you put the values you want to compare with the variable or expression.First, you put a variable or expression that you want to test within parentheses after the switch keyword.Let’s examine the switch statement syntax in more detail: The following illustrates the PHP Switch Case Statement syntax This is exactly what the switch statement is for. In many occasions, you may want to compare the same variable (or expression) with many different values and execute a different piece of code depending on which value it equals to. The PHP Switch Statement is similar to a series of IF statements on the same expression.
