If so, then care must be taken to ensure that both expression-2 and expression-3 (and, of coarse, expression-1) are valid, which makes using the ternary operator somewhat more complicated than it might at first seem, such as when handling optional parameters.
So you should never expect the same behavior in any of them. every other language with a similar operator, ? For all other cases adapt your code accordingly.Which is also usable in PHP in the same way.
Back in my day, all we had was...OK, I had all of these things too. Many people are so hooked on the typical logic that if/else requires specifically if and else and brackets { }. Often if/else statements get way too complicated. :)These are nice shorthands, but be warned, it will make your code unreadable and less understandable.If you code for longer, you start to let go of niftyness and look more towards readability.What is wrong with this code, I keep receiving an error.I have a bit of a word of advice here on the use of ternary and collaboration. :) operator helps a lot. Embedded ternary operators, and nested ternary operators are a developer’s worst nightmare – it creates unnecessarily unreadable code that is difficult to maintain. I have a table in which one field id exist. Dave addresses that in his points above, “Tips for Using Ternary Operators”. Echo can take multiple strings as arguments. Another disadvantage for the operators ternary is more slow than the operator traditional, or not?For flexibility yes, for readability no. I use this quite often now for example in this context:Technically yes, but the ternary operator lets you output whatever you want (i.e.
For example it can make maintaining the code slower and harder instead of quicker and easier if the expression in the ternary operator is not completely basic.
A deeply nested if/else simply understands the flow of logic without them. Oh, and the texting, always the texting. Write it in a way that works either for both or decently for both.Wow! Ternary operator logic is the process of using "(condition) ? : (on false) returns the result of condition if the condition is true. IE so many )))))))))); at the end of a deeply nested ternary. But parts of the page does not display under Opera/NetBSD. This trick only works in PHP 5.3+ and can sometimes make your logic even shorter. that you can do this:The ternary operator IS NOT the same as if/else; a ternary operator assures that a variable is given an assignment.I did want to add that in PHP ternary does not always make code shorter than a if/else. "Conditional Operator" is actually descriptive of the semantics, and is the name historically given to it in, e.g., C. Needless to say, if PHP picked up any more ternary operators, this will be a problem. The final line is called the "conditional expression" in python, although I've seen it called the ternary operator in python as well. Though with deeply nested if/else you can forgo the brackets, you can not with ternary. Which you can forgo in a deeply nested if/else, which the blow structure can also be a part of.Don’t do stupid things with PHP. Though be pleasantly surprised is they are. I use this all the time. The video games.
Expression expr1 ? I don't know if this helps, but the php expression looks a lot like what is called the "ternary operator" in C-like languages. It makes the code a lot shorter and once you are used to it even easier to read. Given that you can code in similar if/else blocks to that of ternary. Ternary operators are more commonly known as conditional expressions in Python. I did not know that you don’t have to put a value after the question mark i.e. Here is a blueprint and an example of using these conditional expressions. This demonstrates how much more flexibility you get when using the ternary operator. Then when you do deeply nested ternary you then use ( ). :) ... Exemple. Wrapping the expressions in the ternary operator with parentheses is optional. As a rule I use ternary only if the If/Else is a ‘single line of code’ <— Yes this is variable depending on screen size.
I have a background in Java so coming to PHP I see many similar coding between the two. Expression expr1 ? One thing should be mentioned though – this should definitely not be used heavily. The former name merely notes that it has three arguments without saying anything about what it does. a string “IT’S BIGGER!”, and not just true or false like in your example. It looks like a mess at first glance if overused and I’m not a fan of it unless i need to use it. You’re doing great job revealing PHP mysteries.wish we had a syntax to test something and assign it to l_value if the test was successfully = x > 4 ? These operators evaluate something based on a condition being true or not.
