Manipulating an object returned from function

Consider this cde:

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

function &getInstance () {
static $instance;

if(!isset($inst ance)) {
$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_OPERAT OR, 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.

Hello =) I have an object which contains a method that should execute every x ms. I can use setInterval inside the object construct like this - self.setInterval('ObjectName.methodName()', this.pinginterval); - but is there no way to do this without using the literal ObjectName? If I write 'this.methodName()' I get "Line 1 Char 1: Object doesn't support this property or method." in IE, and nothing happens in Firebird.

Hi I have a problem with a customer's XML being submitting to me in a non-well-format XML. They said that there are 18 other partners who has been able to tweak the XML to make it work. So I guess here is my question, in ASP, when working with XML, how do you handle non-well-formed XML documents on the "listener" response side? Here's the scenerio: Customer post XML Data to us (non-well-formed XML)

Evening everyone... First, this is a homework assignment and I am not looking for the direct answer (notice no code...), but instead I need direction to help figure this out.

I have passed the pointer to the encrypt function (debug code reveals - output statement). I need to increase the value by 1 in the encrypt...

Hi all, I am relatively new to socket programming. I am attempting to use raw sockets to spoof my IP address. From what I can tell I will have to build from the Ethernet layer on up. This is fine, but I am having some trouble with manipulating my hex values. Seems to me that there are two ways to store hex values: 1. as literal hex - 0x55aa 2. as a string - "\x55aa"

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
