PHP If…Else Vs Switch…Case
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.
Consider the following example, which displays a different message for each day.
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.
This Example for Without Break:-
This Example for different case to same Statements
This Example for one case two Statements
This Example For variable not match so print is default
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.
