switch ($i) { case A: $letter = 'first'; break; case B: $letter = 'first'; break; case C: $letter = 'first'; break; case D: $letter = 'second'; break; default: $letter = 'third'; } Is there any way to shorten first three cases?
They have the same values inside.

Control passes to the case statement whose constant-expression value matches the value of expression . The switch statement can include any number of case instances. However, no two constant-expression values within the same switch statement can have the same value.
A switch statement includes literal value or is expression based. A switch statement includes multiple cases that include code blocks to execute. A break keyword is used to stop the execution of case block. A switch case can be combined to execute same code block for multiple cases.
There can be one or 'N' number of cases in a switch statement. The case values should be unique and can't be duplicated. If there is a duplicate value, then it is a compilation error. The data type of the values for a case must be the same as the data type of the variable in the switch test expression.
switch ($i) { case A: case B: case C: $letter = 'first'; break; case D: $letter = 'second'; break; default: $letter = 'third'; } Yep there is. If there's no break after a case, the code below the next case is executed too.
