Manipulating an object returned from function

[Ryan Govostes]

Consider this cde:

/**********
class testClass {
var $value = 6;
}

function &getInstance() {
static $instance;

if(!isset($instance)) {
$instance = new testClass;
}

return $instance;
}

echo getInstance()->value;
/**********/

In PHP5, this correctly echos '6'. However, in PHP4, I get

Parse error: syntax error, unexpected T_OBJECT_OPERATOR, expecting ','
or ';' in /test.php on line 16

I do need to the code in this format, without splitting it into two
lines (which I know works). It would be detrimental to my project if
it turns out this won't work at all :-\

PHP 4 doesn't support this syntax.

If you really want to use OOP and its features, then drop PHP 4 and use
PHP 5.

PHP 4 is reaching its end of life this year (see <http://www.php.net/>),
while PHP 6 is going to see the light of day in maybe a few months.
