Pass by reference

[novicetillnow]

Hi,

 

I read in  PHP.net site that "Function definitions alone are enough to correctly pass the argument by reference As of PHP 5.3.0, you will get a warning saying that "call-time pass-by-reference" is deprecated when you use &".

 

Does that mean,

 

function foo(&$var)

foo($a);

 

AND

 

function foo($var)

foo($a);

 

will have same impact? While passing $a, it is treat as Pass by reference by itself???

 

Thanks,
