if...else Statements

We can used conditional statements to perform different actions, based on different conditions. There are 4 conditional statements in PHP. For instances:

• if - to execute code only a specified condition is TRUE.
• if..else - to execute code if a condition is TRUE, and another code if a condition is FALSE.
• if..elseif..else - to select one of several blocks of code to be executed.
• switch - to select one of many blocks of code to be executed.
