Make all variables global, PHP

Question

Is there a way to make all variables global?

Answer 1

You Can simple make them a reference to $GLOBALS

foreach($GLOBALS as $k => $v)
   $$k=&$GLOBALS[$k];

---

Explanation of the code:

$GLOBLAS is a superglobal variable (visible everywhere). Basicly it contains all variables

---

$$ means the variable with the name of the value of the variable you wrote

Bit weird to explain in a foreign language so here's an example:

$color='blue';
$blue='foo';

echo $$color;

will output

foo

---

$k=& $v;

means that $k is a reference to $v
