$x ? xxx : xxx

But it makes your code less readable IMHO and offers no tangible benefit
whatsoever.

It offers the tangible benefit of evaluating to something:

return (isset($foo) ? $foo : $bar);

$query = select * from foo
 .(isset($bar) ?  where bar = ${bar} : '');

$foo = ((count($bar)  1) ? 'bars' : 'bar);

[PHP] Control Structure Syntax Question

[Ahbaid Gaffoor]

Someone had posted a tip for using an abbreviated form of an if.. else 
structure...

It looked something like:

$x : action1 : action2;

I'm trying to shorten having to do the following:

if ($x) {
 action1;
} else {
 action 2;
}
can someone please post the syntax if they know it? I am reading the 
fine documentation but can't find it...

many thanks

Ahbaid

Yeah, but if my code is less readable, my job security goes up ;) (Kidding)

Thanks for all your help folks,

that's what I needed.

Before this thread dies, I'd like to clarify something. This syntax is 
mostly for inline ifs as what it does is return a value. For example:

$apples = 2;
echo 'There are '.$apples.' apple'.($apples == 1 ? '' : 's').'.';
In this case, it returns a string which is then echoed. This *could* be 
used in place of a normal if, but there is probably an added overhead as 
the value of the last statement is returned. Also, you *must* have an 
else when you use this syntax (even if it does nothing), it cannot be 
used for a simple if.

Ah, to each his/her own I guess ... I actually find:

$value = ($condition ? $val1 : $val2);

easier to read than:

if ($condition)
$value = $val1;
else
$value = $val2;

On the other hand for this:

$value = ($var1  ($var2 == 4)  (($var3 == $var7) || ($var9 ==
hello))) ? htmlspecialchars(strstr($string1, $string2) . test) :
NULL;

I would prefer to use:

if ($var1  ($var2 == 4)  (($var3 == $var7) || ($var9 ==
hello)))
$value = htmlspecialchars(strstr($string1, $string2) . test);
else
$value = NULL;

In other words ... IMO you can use the ?: operator to be concise (which 
increases readability) or to be cryptic (which reduces it).
