Hello,
I know that PHP doesn't support pointers to a variable, instead of that
there is references to a variable which are similar to pointers, right?
BTW, what I want to do is to save a references to a variable and read the
content when I need, similar to PDO "bindParam". I will try to explain
better in the following pseudo php code.
function foo($a) {
$GLOBALS['references']['a'] = /*references to $a */
}
function bar() {
echo $GLOBALS['references']['a'];
}
$var="hello"
foo($var);
$var = "hi";
bar(); /* it should print "hi" instead of "hello" */
