With this we come to an end of this article, I hope you understood the ternary operator, the purpose and advantages of the ternary operator, Ternary shorthand and Null coalescing Operator.

Instead of writing some lengthy code like this: $user= isset($_GET) ? $_GET : 'nobody' It will fetch the value of $_GET and returns ‘nobody’ if it does not exist. Syntax: (Condition)?(Statement1)?(Statement2) It replaces the ternary operation in conjunction with isset() function which is used to check whether a given variable is NULL or not and returns its first operand if it exists and is not NULL else it returns the second operand. The ternary operator follows the following syntax: If the boolean expression evaluates. Is not set, instead of writing some lengthy code like this: $val = isset($_GET) ? $_GET : 'default' The ternary operator is a way to quickly express if/else statements.

If you use the ternary shorthand operator like this, it will cause notice if $_GET It will return the first operand if the operand is true else it evaluates and returns its second operand. In this tutorial, you will learn about the conditional operator. Here, three different operations will work in conjunction to make a single operator. The PHP ternary operator is another way to implement this concept with a different technique. It is the ternary operator with the second operand omitted. You might have read about the 'if-else' conditional statement of PHP. It is also referred to as Elvis operatory(?Įlvis operator can be used in order to reduce redundancy of your conditions and shorten the length of your assignments. Short ternary operator syntax can be used by leaving out the middle part of the ternary operator for quick shorthand evaluation. If/Else statements aren't optimal (or necessary) in all situations. I preach a lot about using shorthand CSS and using MooTools to make JavaScript relatively shorthand, so I look towards PHP to do the same. If / Else statements are great but they can be too long.

In order to get the values of our text fields, we can use the following code: If / Else statements are easy to code and global to all languages. Let’s look at an example of a validation form for better understanding:

#Php if else statement shorthand registration#

$reg_number = (isset($_POST)) ? $_POST : die('Please enter your registration number') if the registration number is not specified, notify the customer It returns its first operand if it exists and is not NULL otherwise it returns its second operand.

If you are like me, and continually having to look this up here you go: One Line If Statement Example php myvalue 99 x (myvalue 99) 'x is 99': 'x is not 99' echo ('
'.

Let’s say, we were programming a login form for a college university where we wanted to ensure that the user entered their registration number provided by the university then we could move further. It has also been called the short if statement and the single line if statement. Moreover, it is commonly used when we assign post data or validate forms. We use ternary operator when we need to simplify if-else statements that are used to assign values to variables.

Statement 2: It is the statement to be executed if the condition results in a false state.Įxample program to whether student is pass or fail: =40) ? "pass" : "Fail".

Statement 1: it is the statement to be executed if the condition results in a true state.

Condition: It is the expression to be evaluated which returns a boolean value.

Syntax: (Condition) ? (Statement1) : (Statement2) It is called a ternary operator because it takes three operands – a condition, a result for true, and a result for false. It also produces an e-notice while encountering a void value with its conditionals. Obviously, it is the best case for a time-saving option. The order of execution for this operator is from left to right. This method is an alternative for using if-else and nested if-else statements. The ternary operator is a conditional operator that decreases the length of code while performing comparisons and conditionals. Use an if / else, a switch or possibly an associative array as appropriate. In this Ternary Operator PHP, we will see how it is used for shortening conditional statements. 7 Answers Sorted by: 5 You can of course 'chain' the ternary operator, but that results in horrible code. We always look for shortcuts everywhere whether it is a route for traveling or game or code. Using the if-else and switch case is an essential part of programming for evaluating conditions.
