[ACCEPTED]-create superglobal variables in php?-php
Static class variables can be referenced 1 globally, e.g.:
class myGlobals {
static $myVariable;
}
function a() {
print myGlobals::$myVariable;
}
Yes, it is possible, but not with the so-called 4 "core" PHP functionalities. You 3 have to install an extension called runkit7: Installation
After 2 that, you can set your custom superglobals 1 in php.ini as documented here: ini.runkit.superglobal
I think you already have it - every variable 2 you create in global space can be accessed 1 using the $GLOBALS
superglobal like this:
// in global space
$myVar = "hello";
// inside a function
function foo() {
echo $GLOBALS['myVar'];
}
Class Registry {
private $vars = array();
public function __set($index, $value){$this->vars[$index] = $value;}
public function __get($index){return $this->vars[$index];}
}
$registry = new Registry;
function _REGISTRY(){
global $registry;
return $registry;
}
_REGISTRY()->sampleArray=array(1,2,'red','white');
//_REGISTRY()->someOtherClassName = new className;
//_REGISTRY()->someOtherClassName->dosomething();
class sampleClass {
public function sampleMethod(){
print_r(_REGISTRY()->sampleArray); echo '<br/>';
_REGISTRY()->sampleVar='value';
echo _REGISTRY()->sampleVar.'<br/>';
}
}
$whatever = new sampleClass;
$whatever->sampleMethod();

One other way to get around this issue is 6 to use a static class method or variable.
For 5 example:
class myGlobals {
public static $myVariable;
}
Then, in your functions you can 4 simply refer to your global variable like 3 this:
function Test()
{
echo myGlobals::$myVariable;
}
Not as clean as some other languages, but 2 at least you don't have to keep declaring 1 it global all the time.
Not really. though you can just abuse the 2 ones that are there if you don't mind the 1 ugliness of it.
You can also use the Environment variables 4 of the server, and access these in PHP This 3 is a good way to maybe store global database 2 access if you own and exclusively use the 1 server.
possible workaround with $GLOBALS
:
file.php:
$GLOBALS['xyz'] = "hello";
any_included_file.php:
echo $GLOBALS['xyz'];

One solution is to create your superglobal 5 variable in a separate php file and then 4 auto load that file with every php call 3 using the auto_prepend_file
directive.
something like this 2 should work after restarting your php server 1 (your ini file location might be different):
/usr/local/etc/php/conf.d/load-my-custom-superglobals.ini
auto_prepend_file=/var/www/html/superglobals.php
/var/www/html/superglobals.php
<?php
$_GLOBALS['_MY_SUPER_GLOBAL'] = 'example';
/var/www/html/index.php
<?php
echo $_MY_SUPER_GLOBAL;
