@solidaritiauthorSep 21.2005 — This doesnt seem to work, it says that there is an unexpected T_ECHO I've tried putting a semi colon between the two echo statements and : but that doesnt seem to work.

So its like a shortened if statement then?

echo (1 == 2) ? "I can't count" : "I can count";

@NogDogSep 21.2005 — PS: It is called the "ternary operator". More info on this page: http://www.php.net/manual/en/language.operators.comparison.php
The expression [i](expr1) ? (expr2) : (expr3)[/i] evaluates to expr2 if expr1 evaluates to TRUE, and expr3 if expr1 evaluates to FALSE.[/quote]

@Stephen_PhilbinSep 21.2005 — Aye, weirdly, using the sort-hand if structure seems to return the selected result rather than execute it as a standard if structure would do.

@felgallSep 21.2005 — A = B ? C : D;

is equivalent to

if (? {A = C;} else {A = D;}

@SpectreReturnsSep 22.2005 — And by return he doesn't mean using 'return'. He means returning a value to use later on in the script (but can be used for 'return' if you want).

[code=php]
$test = ((true) ? "true" : "false"); // good use
((true) ? echo("hello") : print("sup")); // Bad use
[/code]

if ($a == $b)

{

echo "THIS IS VALID";

}

else

{

echo "THIS IS NOT VALID":

}

short hand for writing if statement

echo ($a==$b) ? "THIS IS VALID" : "THIS IS NOT VALID" ;

Success!
