If you use the ternary operator, you can write conditional statements more concisely than the if statement, the code is also very convenient to clear. There are few nice ways to write shorthands in PHP. Using the above operators will simplify your code, so go ahead and use them! In this article, I have introduced some operators. But it helps us write the statement in a shorter format.
The Elvis operator (? :) is equivalent to $hoge ? There are differences such as $hoge : equivalent to $fuga. The following is an if structure with elseif and else in the alternative format: The Null coalescing operator (?) is equivalent to !is_null($hoge) ? $hoge : $fuga is equivalent to There is also a short-hand if else, which is known as the ternary operator because it consists of three operands. The behavior is a bit similar to the Null coalescing operator, but The description is in the form of $hode ? : $fuga. Making statements based on opinion back them up with references or personal experience. Do use the ternary operator when it makes your code more concise and more readable. The Elvis operator (? :) is a ternary operator (conditional expression ? expression1 : expression2) in which the expression1 part is omitted. The ternary operator ( : ) is a shorthand for the if.else statement. You can check if the value is set, and if not, you can shorten the description when you want to assign some value. If $userName is non-null, it returns "$userName" of the first operand, and if null, it returns "none" of the second operand. buat sebuah file php dengan nama belajar.php. dan berikut ini contoh sederhana dari penggunaan kondisi if else pada php. berikut ini adalah format cara penulisan if else pada php. The description is in the form $hoge ? $fuga. Mengenal Kondisi If-Else pada PHP Kondisi If Else di perlukan untuk memeriksa suatu nilai untuk melakukan suatu aksi. The Null coalescing operator (?) was added in PHP 7.0 as a syntax sugar for !is_null($hoge) ? It was added in PHP 7.0 as a syntax sugar for $hoge : $fuga. Use ternary operators within ternary operatorsĮcho ($rand % 2 = 0) ? (50 <= $rand ? 'even number greater than 50' : 'even number less than 50') : (50 <= $rand ? 'odd number over 50' : 'odd number under 50') Įcho 50 <= $rand ? 'Even number greater than 50' : 'Even number less than 50' Įcho 50 <= $rand ? 'odd number over 50' : 'odd number under 50' Īlthough the contents of the above two processes are the same, I think the code that combines if~else and the ternary operator is easier to understand the flow of the process. However, too much use of ternary operators reduces readability, so it is not recommended to use ternary operators such as calling ternary operators within ternary operators. If you describe the same process using if~else, the amount of code will increase. The following is a concrete code description.Įcho $a = $b ? '$a and $b are the same value' : '$a and $b are different values' The ternary operator can be used by writing the conditional expression ? You can use it by writing expression1 : expression2. In C, if condition is true, first expression is evaluated and becomes. $message = 'Hello '.In this article, I would like to introduce some useful operators that can be used to shorten PHP code.įirst, I'd like to introduce probably the most famous ternary operator. This shorthand form is sometimes known as the Elvis operator in other languages. Use enough parenthesis to keep your code organized, but not so many.Įxample 1: Message according to user's login status.If you are not experienced with using ternary operators, write your code using if-else first, then translate the code into ?'s and :'s.If you work in a team setting, make sure other programmers understand the code.Don't go more levels deep than what you feel comfortable with maintaining.It is used to assign a value to a variable based on a condition. Shorthand comparison, also known as the ternary operator, is a shorthand way of writing an if-else statement in PHP. You can do your if-else logic inline with output PHP if Shorthand Shorthand Comparison in PHP.Makes coding simple if-else logic quicker.
There are many advantages of using this type of logic: $var_is_greater_than_two = ($var > 2 ? true : false) // returns true Advantages of Ternary Logic Ternary operator logic is the process of using " (condition) ? (true return value) : (false return value)" statements to shorten your if-else structures. However, they can be too long. The ternary operator (?:) can replace a single if/else clause. If-Else statements are easy to code and global to all languages.
Almost all the programs require evaluating conditions using if/else and switch/case statements.
