20th Sep - PHP ternary operator ~ Linchakin

In this article, we will understand about a PHP ternary operator with the help of various examples.

What do you mean by Ternary operator?

It is also called a conditional operator. The ternary operator is an operator that decreases the length of code while performing comparisons. It is an alternative for using if-else and nested if-else statements. We can use the ternary operator when there is a need to simplify the if-else statements and to make efficient code out of a complex program structure.

Syntax:

Following is the syntax of ternary operator in php.

(Condition) ? (code1) : (code2);

In the above syntax,

Condition statement: It is a PHP expression that will be evaluated in order to return a Boolean value.
code1: This will be the statement that will be executed when the conditional results will return true.
code2: This will be the statement that will be executed when the conditional results will return in a false state.
