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.

How to extract and access data from JSON with PHP?

I know this question has been asked before.
but whenever I try to get the value of my array it does not work, only difference I can see is the name of a value is a number?
$returnValue = json_decode('{"content": [{"id": 1249029}]}');`
That gives me an array that looks like:
stdClass::__set_state(array(
'content' =>
array (
0 =>
stdClass::__set_state(array(
'id' => 1249029,
)),
),
))
So getting my id should be as simple as:
var_dump($returnValue['content']->0->id);
This code gives me an error 500.
Thanks,
You need to access it like this:
$returnValue->content[0]->id;

What kind of string is this? How do I unserialize this string? [duplicate]

Using Gravity Forms API code GFAPI::get_entries returns an array. Most of the values are straight forward and I have no issues accessing them. However, when it outputs the "List" field it looks like this:
[44] => a:3:{i:0;a:5:{s:7:"Address";s:17:"111 Long St";s:4:"City";s:10:"Southfield";s:5:"State";s:2:"MI";s:3:"Zip";s:5:"48033";s:4:"Type";s:17:"House - Townhouse";}}
How would I set "111 Long St" to a variable? I will need all of the values but I'm sure I can figure it out once I have the answer to getting the Address.
Thanks!
[Edit]
So this is mostly my working code with a few changes to make it easier to read:
$search_criteria["field_filters"][] = array( "key" => "id", value => "10" );
$entries = GFAPI::get_entries( $form_id, $search_criteria );
...
$unserializeArray = unserialize($GLOBALS['entries'][0][44]);
return $unserializeArray[0]["Address"];
http://php.net/manual/en/function.unserialize.php
that's a serialized array in PHP, similar to JSON representation

How to use php serialize() and unserialize()
(10 answers)

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] =>
)

Sorting an Array of Objects in PHP In a Specific Order

Closed 8 years ago.
Supposing you have an object:
$arr = array(
array('name' => 'toto', 'firstname' => 'abc'),
array('name' => 'toto2', 'firstname' => 'aaa')
);
I want to order it by name AND firstname. You cannot use keyword "use" for old version of php like 5.2. If a general function is not possible, then build a function for this specific case.
Thanks.
Use usort with a callback that compares the elements of the array according to the rules you specify in the callback.

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.
