Programmatically declare globals in PHP

Question

Plain and simple like the title says - Is there any way to programmatically declare globals inside a function in PHP? For example, from an array of strings (which are the global variables names)

Yes, if you add variables to the $GLOBALS array they are then globally available like any other global.

function add_globals($arr)
{
    foreach ( $arr as $idx => $name ) {
        $GLOBALS[$name] = $idx;
    }
}

$names = array('aa','bb');
add_globals($names);
echo $aa.PHP_EOL;
echo $bb.PHP_EOL;

RESULT

I am just using the index of the $names array as a value for each new global, you could use anything
