Looking for alternative for compact() function

[bc173]

Hello,

The shortcoming of the compact() function is that it skips empty
variables. I don't want that, so I tried to make my own function to do that. This is the procedure:

1 - use array_walk() to edit each key/value of the array
2 - change the name of the key to it's contents (=value of key)
3 - use eval() to interprete the value as a variable

Now, step 2 seems impossible. Is there any other way to achieve what I want?

Thanks,

Barton

This sounds interesting, so I've given it a try:

function myCompact() {
	$ret = array();
	$argnum = func_num_args();
	for ($i = 0; $i < $argnum; $i++) {
		$varname = func_get_arg($i);
		global $$varname;
		$ret[$varname] = $$varname;
	}
	return $ret;
}

However, this function must be supplied with the name of the variables, not the variables themselves.
