The if, elseif …else and switch statements are used to take decisions based on the different conditions.
In PHP we have the following conditional statements:
if()statement – executes some code if one condition is true
if()...elsestatement – executes some code if a condition is true and another code if that condition is false
if()...elseif()...elsestatement – executes different codes for more than two conditions
switchstatement – selects one of many blocks of code to be executed
