function debug($var$val)
{
    echo 
"***DEBUGGING\nVARIABLE: $var\nVALUE:";

is_array($val) || is_object($val) || is_resource($val)) {

Note: Referenced variables in param_arr are passed to the function by a reference, others are passed by a value. In other words, it does not depend on the function signature whether the parameter is passed by a value or by a reference.
