When you want to implement different conditions in your program, you use the If…Else…ElseIf statement. If one condition is true, the other condition is also true – If statement If one condition is true and the other condition is false – If…else statement If more than two conditions are required – If…else…elseIf statement selects multiple blocks of code One to be executed – Switch statement if…else…elseif statement:
<!DOCTYPE html><html><body><?php$t=date("H");echo" <p> Hey There,\n </p> ";if($t<"10"){
echo"Have a good morning!";}elseif($t<"20"){
echo"Have a good day!";}else{
echo"Have a good night!";}?></body></html>
Output:
Switch statement:
<!DOCTYPE html><html><body><?php$favfood=" ";switch($favfood){
case"Spaghetti":echo"Your favorite food is Spaghetti!";break;case"Pasta":echo"Your favorite food is Pasta!";break;case"Sandwich":echo"Your favorite food is Sandwich!";break;default:echo"Your favorite food is neither Spaghetti, Pasta, nor Sandwich!";}?></body></html>
