Thanks for your response! While it does not cause a crash, your
function doesn't do what I expected. Do you know where I went wrong?
This script:
<?
if(!extension_loaded('foo')) {
dl('foo.so');
}
//make two variables
$foo = "foo";
$bar = "zonk";
//reference assignment
stas_ref_assign($bar, $foo);
//should be identical
echo "$foo\n";
echo "$bar\n";
//set foo and bar to "baz"
$bar = "baz";
//should print "baz"
echo "$foo\n";
?>
Outputs "foo zonk foo", and I expected "foo foo baz".
I made the following function:
PHP_FUNCTION(stas_ref_assign)
{
zval **dest, **src;
if (ZEND_NUM_ARGS() != 2 || zend_get_parameters_ex(2, &dest, &src)) {
WRONG_PARAM_COUNT;
}
SEPARATE_ZVAL_TO_MAKE_IS_REF(src);
(*src)->refcount++;
zval_ptr_dtor(dest);
*dest = *src;
}
with the function entry:
PHP_FE(stas_ref_assign, first_arg_force_ref)
Thanks,
-Tim
