How to get the names of all subobjects?

[René]

Hello,

My example:

$person->telnumber->value
$person->faxnumber->value
$person->???

The names of the objects "telnumber" and "faxnumber" (and further
possible subobjects) are not known for me.

How can I get the names of all subobjects of an object?

Thanks a lot.
René

I reckon you're talking arrays here...(?)
You can then find both the keys and values of the array by doing this;

foreach ($person as $key => $value) {
echo "$key is $value \n";
}

I.e. if (by your examples) some keys and values are like this[color=blue]
> $person->telnumber->555-1515
> $person->faxnumber->555-2121
> $person->address->Big Street[/color]
The above code will echo the following:
telnumber is 555-1515
faxnumber is 555-2121
address is Big Street

Hope this was what you're looking for.

If you use the function "get_class_vars ", you can get a list of all the
properties of the class. Loop through each element of the resulting
array, and use the "is_object" function to determine if it's an object.

$class = new Classname();
$vars = get_class_vars( $class);

while ( list($name, $val) = each($vars) ) {
if ( is_object($val) ) {
print $name . " is an object!\n";
// to reference the property directly - not sure in how
// many versions of PHP this works in
$subclass = $class->$name;
print_r($subcla ss);
print "\n";
}
}
