The switch statement in PHP is a control structure used to execute different blocks of code based on the value of a variable or expression. It is similar to a series of if...elseif...else statements but is often used when you want to compare the same variable or expression against multiple possible values.
Syntax of the switch Statement
switch (expression) {
case value1:
// Code to be executed if expression equals value1
break;
case value2:
// Code to be executed if expression equals value2
break;
case value3:
// Code to be executed if expression equals value3
break;
default:
// Code to be executed if none of the cases match
}
switch (expression): This is the value or expression to be compared.case value:: If the value of expression matches value, the associated block of code is executed.break;: This exits the switch block after a matching case is found and its code has been executed, preventing subsequent case blocks from running.default:: This block executes if none of the case values match the expression.Try it yourself
break; is used to exit a loop or switch block immediately.switch statements to prevent further execution once a condition is met.Warning
Without break;, PHP will continue to execute the next case statements (known as "fall-through" behavior).

The default keyword in PHP is used in a switch statement to specify the block of code that should be executed if none of the case values match the evaluated expression.

default Placed ElsewhereAlthough not common practice, the default block can be placed anywhere within a switch structure. PHP will execute the default block if no matching case values are found, regardless of its position.
