[SOLVED] $captcha =& new captcha($CAPTCHA_CONFIG);

What does the =& do? I would have put just an = sign there.

 

$captcha =& new captcha($CAPTCHA_CONFIG);

$foo = 'bar';

$bar =& $foo;

 

$bar = 'foo';

 

echo $foo; // returns foo

 

$bar =& $foo $bar references $foo any changes made to $bar have effect on $foo

Yeah, it's the reference operator.  Almost remotely like pointers in C and C++, but not the same. >_>

Almost remotely like something, but not the same? Haha, makes perfect sense

I don't want to say that they're like pointers because they're not.  They sort of act like pointers.  Almost.  Sort of. >_>  *Dies*
