Today I will discuss about the conditional statement in PHP. Like other language PHP allows you to make decision based on the some condition.

There are several conditional statements in PHP that you can use to make decisions:

• The if statement
• The if else statement
• The if elseif else statement
• The switch case statement
•  Ternary operator

Let us demonstrate some example:

Few days ago I posted on facebook two picture those are bellows,

The output Of this code is : "Hello I am PHP".

The Output of this code is :"Hello condition 1 is true".

In first program, we notice that the initial value of x is 1. then by ++$x oparetor it adds 1 with x. then x will 2. So the first condition is true. After executing the code inside the If condition x will 3 but else condition would not true.

According to the Conditional Statement If one condition is true then the other condition is false.
Then in the second program both if condition and else if  condition is true.

But a question is arise which condition is allowed both of them.

The answer is very easy. It will be first true condition always. 

I  think everybody understand this.
