PHP Switch…Case Statements

The switch-case statements are used to test an expression with different values.

The switch-case statement is an alternative to the if-elseif-else statement, which does almost the same thing. The switch-case statement tests a variable against a series of values until it finds a match, and then executes the block of code corresponding to that match.



The switch-case statement differs from the if-elseif-else statement in one important way. The switch statement executes line by line (i.e. statement by statement) and once PHP finds a case statement that evaluates to true, it’s not only executes the code corresponding to that case statement, but also executes all the subsequent case statements till the end of the switch block automatically.

To prevent this add a break statement to the end of each case block. The break statement tells PHP to break out of the switch-case statement block once it executes the code associated with the first true case.

This is the tutorial on how to use PHP Switch Case Statements.
