If ....else is another php conditional operator .When working with the if statement , You will often want to define an alternative block of code that should be executed if the expression you are testing evaluates of false. You can do this by adding else to the if statement followed by a further block of code. like so:
if(expression)
{ //code to execute if the expression evaluates to true }
else { //code to execute in all other case }
