Switch Statement

Explore the PHP switch statement to control program flow by evaluating multiple conditions efficiently. Understand how to implement cases, use breaks to prevent fall-through, and apply a default case for unmatched values.

We'll cover the following...

Switch Case Construct #

Typically this is required when based on different values of a particular expression, different actions need to be performed. The basic construct of a switch case looks as follows:

C++
switch (expression)
{
  case constant-expression: 
     statement; //statement(s) execute if constant-expression is true
     break; //exit the switch block 
  default: //the code inside default is run when no other cases match
     statement;
     break;
}

  • In the code block above the expression can have multiple values. Essentially:

    • string
    • integer

  • case ...
