What is question mark in PHP?

[bilis_money]

I know this is basic but,

 

I took an exam on PHP and i dropped it. too bad. 

 

I really don't know the meaning of this ? on php?

What question mark can do on php?

 

Could you give me an example.

 

Thanks in advance.

Ha...What are you asking?

[Psycho]

It depends in what context you are talking about.

 

For example in this case:

HTML goes here

<?php

//php code goes here

?>

HTML goes here

 

The ?'s are used to identify the beginning and end of PHP code

 

In this case

$var = ($x ==1) ? 'a' : 'b';

It is used as part of a tertiary operator.

What language is native to you?

 

 

The question mark has several purposes. The most common are probably the beginning and end tags for PHP inside HTML:

 

<?php

    echo 'Hello world.';

?>

 

 

And passing variables through URLs:

 

http://www.domain.com/news.php?article=5876773

 

 

And others.

It is part of the ternary operator if used in a script. You may also see it in a url in which case it is a separator between the url and  variables.

HA HA HA 

 

You are all also very very funny. You don't understand the ? on php.

 

The exam really that i took is very hard than i expected.

 

I tested this example codes below,

 

<?php
????? $var=10;???
?????
??? echo "Testing!"; ??
?????
?>

 

and the outcome it says nothing really happens, meaning the question mark doesn't affect anything on the code.

 

Now i know it is nothing... HA HA HA clever Test. 

 

 

Thanks anyway, but i think if i dare you to take the exam you guys will also drop it.

 

I"m sure. ha ha ha

yes, "nothing" will happen because that won't even compile.

[leonglass]

Parse error: syntax error, unexpected '?' in /var/www/localhost/htdocs/gamvc/index.php on line 2

is what happens.

Maybe its some sort of comment like #    ;p

Can I administer an English exam?

[BlueSkyIS]

You are all also very very funny. You don't understand the ? on php.

[Jessica]

Uhm, where is this exam?

[redarrow]

[FridayRain]

You are all also very very funny. You don't understand the ? on php.

 

Are you trying to imply that we're the dense ones here? The question mark serves several roles. Your silly example, which would never be part of actual code, arguably doesn't return the result you say it does. If you aren't going to use question marks correctly, especially to prove this stupid, irrelevant, useless point, who cares?

 

Let me conjure up an imaginary English exam so you can explain the purpose of question marks "on English" and, regarding the exam, "drop it."
