set variable if not set

[optik]

Just wondering if there is a shorthand way of doing this like !$my_variable="value";

Rather than using if statements?

Hi there Optik,

This would be the best I would say, a good old ternary:-

$my_variable = (isset(a_value) ? 'case true': 'case false');

Though it does depend on what you are trying to do, and the context of how you are doing it.

if (!isset($var)) {
$var="foo";
}

That's all I'm doing checking if the variable is set and if not setting the variable, just seems like that could be streamlined to a one liner.

It can be.

if (!isset($var)) {$var="foo";}

$var = (isset($var))? $var : 'foo';

Hi all :)

Almost :)

Example:-

if (!isset($var)) {
$var="foo";
}

turns into this with a ternary:-

$var = (!isset($var) ? $var : 'foo');

It needs assigning if not set, though I am sure by now that you get the jist! ;-p I'm not arguing Readie! Honest! it's too humid for that!

Cheers,
