Get Instance ID of an Object in PHP
I'm new to OOP and I have an object. If I:
var_dump($obj);
I get:
object(stdClass)[55]
public 'date' => int 1295297161
public 'id' => int 11
How can I retrieve the "55"?
As others have mentioned you can't read it, without parsing the output of var_dump. But if all you are looking for is a way to uniquely identify an object, then you should use spl_object_hash.

I have an XML with product. I have a problem with read values witch has a "-" in name because this method dosent work:
$productHurtoID = $product->kod-kreskowy->__toString();
Below You have $product variable:
SimpleXMLElement object {
nazwa => SimpleXMLElement object
kod-katalogowy => (string) K0428
kod-kreskowy => (string) 0027084373370
}
Thanks for help. Kind regards
You could access your dynamically created properties via
$productHurtoID = $product->{'kod-kreskowy'}->__toString();
A different approach would be to pre-process your XML input and replace hyphens with camelCase. But depending on your use-case, this might not be possible.
Regards
You can use following code for getting values with - (hyphen) in key.
$productHurtoID = $product->nazwa->{'kod-kreskowy'}->__toString();

I need to extract the name of the png which in this array is: 56f26f5862fb85.90873638.png. The value is the following context:
i:204;s:27:"56f26f5862fb85.90873638.png";
It would be really convenient if I could look the name after the 204 which is always fixec.
Any guidance or suggestion as for how to solve it is much appreciated.
That is a serialized PHP value, created using the serialize() function.
You can unserialize it using the unserialize() function:
$data = unserialize('a:2:{s:18:"_gravity [...] tal";s:5:"Total";}}');

How to use php serialize() and unserialize()
(10 answers)
Closed 8 years ago.
Data like:
a:5:{i:0;s:0:"";i:1;s:0:"";s:7:"message";s:0:"";s:5:"medal";N;s:5:"users";s:0:"";}
and what's this datatype?
The datatype is a non-standard protocol which exists only within the php-src scripting language.
To properly create a PHP value from a stored representation you would use the unserialize()` function provided by the SPL.
unserialize('a:2:{s:9:"usergroup";s:0:"";s:6:"verify";s:0:"";}');
unserialize() takes a single serialized variable and converts it back into a PHP value.
Couldn't have been that hard if you tried
print_r(unserialize('a:2:{s:9:"usergroup";s:0:"";s:6:"verify";s:0:"";}'));
Output:
Array
(
[usergroup] =>
[verify] =>
)

PHP problem with "__php_incomplete_class"
(5 answers)
Closed 8 years ago.
I am developing a web application in PHP and MySQL.
I get some data from the database and set it into a PHP Object. When I do a var_dump() of the variable that contains the information, I see this:
object(__PHP_Incomplete_Class)[2]
public '__PHP_Incomplete_Class_Name' => string 'Empresa' (length=7)
public 'IDEmpresa' => string '13' (length=2)
public 'Nombre' => string 'Prueba' (length=6)
... other attributes
Why the object is "__PHP_Incomplete_Class" and what are the implications of this?
Thanks!
It means that you've unserialized (presumably from the session) an object whose class is not defined in current runtime.

I'm doing a print_r on an object that is returned after running a query. Here is my print_r log.
stdClass Object
(
[MAX(sort_order)] => 3
)
I want to get the value inside [MAX(sort_order)] but I cant figure out how to target it from within php.
Like $sort_order = $object->[MAX(sort_order)]; (I know that won't work)
Does anyone know how I can do this?
Try add this in your query MAX(sort_order) AS max_sort_order in your query
