Question

I have serialize values in data base, i fetch them from database then when i do

<pre>
print_r($DataValues)
</pre>

it shows me value like this

[0] => stdClass Object
    (
        [categories] => a:1:{i:38;s:21:"Summer Market Session";}
    )

[1] => stdClass Object
    (
        [categories] => a:1:{i:38;s:21:"Summer Market Session";}
    )

[2] => stdClass Object
    (
        [categories] => a:2:{i:38;s:21:"Summer Market Session";i:39;s:21:"Autumn Market Session";}
    )

i want to get only the value after unserializing it, i tried to unserialize but is show bolean false

& when i try to print the value after running for each value it shows me below mentioned error

Catchable fatal error: Object of class stdClass could not be converted to string

I dont know how i do this i was trying all unserialize tactics what i know & also i tried to store value in array by using foreach loop but i am fail..

Kindly help how can i get value of it after unserilize it…??

Well, somehow I still can’t see the problem. I’ve reconstructed the data structure you seem to get from DB with this:

$testObject             = new stdClass();
$testCategories         = array(38 => 'Summer Market Session');
$testObject->categories = serialize($testCategories);

$anotherTestObject             = new stdClass();
$anotherTestCategories         = $testCategories;
$anotherTestCategories[]       = 'Autumn Market Session';
$anotherTestObject->categories = serialize($anotherTestCategories);

$dataValues = array(
  $testObject, clone $testObject, $anotherTestObject
);

print_r($dataValues);

It gave me the same output you’d quoted in your question, so I guess that’s a correct reconstruction. To unwrap this data back, simple loop sufficed:

foreach ($dataValues as $dataElement) {
  $categories = unserialize($dataElement->categories);
  print_r($categories);
}

Or am I doing something wrong?

Anyway, here’s a sandbox to check all this.
