PHP switch Statement

The switch statement is similar to the series of if-else statements. The switch statement performs in various cases i.e. it has various cases to which it matches the condition and appropriately executes a particular case block. It first evaluates an expression and then compares it with the values of each case. If a case matches then the same case is executed. 

To use the switch, we need to get familiar with two different keywords namely, break and default.

• break: The break statement is used to stop the automatic control flow into the next cases and exit from the switch case.
• default: The default statement contains the code that would execute if none of the cases match.

Syntax:

switch(expression)
{
    case val1:
        // Code Statement
        break;
    case val2:
        // Code statement
        break;
    ...
    
    default:
        // Code Statement
}
