PHP switch case Statement
October 25, 2018
PHP switch case statement Use to select one of many blocks of code to be executed.switch-case statement is alternative of 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.

switch case statement excutes line by line thats why its different form if else statement in php. switch statement executes line by line 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.

we add a break statement to the end of each case block. break statement tells PHP to break out execution when conditions meet.
