PHP switch statement is a better alternative than a large series of if-else-if statements. It can switch in different part of the code based on condition. Here is the general form of a PHP switch statement.
switch(expression){
case value1
executed statement;
break;
case value2
executed statement;
break;
………………
default:
// default statement
}
In the PHP switch statement duplicate case values are not allowed. The expression value checks every case iteratively if a match is found then the following case statement is executed. If none of the cases does not matches the value of the expression, then the default statement is executed.
