Problem in array typecast

[girish.kc]

I am using the json_encode function  to store the data in the following format.

 

{"0":"1.1","900":"1.2","1800":"1.3","2700":"1.4","3600":"2.1","4500":"2.2","5400":"2.3","6300":"2.4","7200":"3","8100":"3"}

 

After retrieval, I am decoding the encoded json string and typecasting it to an array as bellow: 

$data = array();
$data = (array)json_decode($db_data);

echo array_search(1.2,$data); 

echo 'Value : '. $data[900];

 

The first echo statement returns 900 as the key, but the second echo returns blank. The array has all the values, is_array($data) returns true.

 

If I add the bellow code then the things work normally.

 

$test_array = array();
foreach ($data as $key => $value
{
        $test_array[$key] = $value;
}

echo array_search(1.2,$test_array); 

echo 'Value : '. $test_array[900];

 

Looks strange to me.

Please advice.

json_decode returns an object by default. You need to set the second parameter 'true' to return an array:

 

$data = json_decode($db_data, true);

 

The problem with your method of typecasting the object will have been within the conversion, but I'm not sure what exactly.
