copied!<p>I asume you can't decode them later, if you would change <code>$company_pk</code> to public it should encode correctly. Problem is with your object cast to array which adds NULL byte to your private member <code>$company_pk</code>. In <code>echo CJSON::encode((array)$ret_val[0]);</code> as it's array of OBJECTS. </p> <p>You can do nasty. </p> <pre><code>$json = '{"\u0000CompanyModel\u0000company_pk":"2"}'; $json = str_replace('\u0000', '', $json); var_dump(json_decode($json)); </code></pre> <p>Or you pass object to <code>CJSON::encode</code> i dont know much of YII but it should handle object, as per manual <a href="http://www.yiiframework.com/doc/api/1.1/CJSON" rel="nofollow">http://www.yiiframework.com/doc/api/1.1/CJSON</a>.</p> <p>Here is example to reproduce issue:</p> <pre><code>class test { private $private = 1; public $publiv = 2; } $obj = new test(); $array = (array) $obj; $json = json_encode($array); var_dump($json); var_dump(json_decode($json)); </code></pre> <p><strong>EDIT</strong>:</p> <p>From the manual <a href="http://www.php.net/manual/en/language.types.array.php" rel="nofollow">http://www.php.net/manual/en/language.types.array.php</a>:</p> <blockquote> <blockquote> <p>If an object is converted to an array, the result is an array whose elements are the object's properties. The keys are the member variable names, with a few notable exceptions: integer properties are unaccessible; private variables have the class name prepended to the variable name; protected variables have a '*' prepended to the variable name. These prepended values have null bytes on either side.</p> </blockquote> </blockquote> <p>I did quick look to <code>CJSON::encode</code> from YII and you can use object directly, but your object must be traversable, so you must implement Iterator interface. <a href="http://www.php.net/manual/en/class.iterator.php" rel="nofollow">http://www.php.net/manual/en/class.iterator.php</a>.</p> <p>EDIT:2 </p> <p>Implementing interface could be tricky, there is another option to call <code>get_object_vars</code> from within object and in this case you will get array which will work.</p> <pre><code>class CompanyModel extends CComponent { private $company_pk; public function getCompany_pk() { return $this->company_pk; } public function setCompany_pk($value) { $this->company_pk = $value; } public function export() { return get_object_vars($this); } </code></pre> <p>}</p> <p>And then:</p> <pre><code>$ret_val = $model->getCompanyList(); echo CJSON::encode($ret_val->export()); </code></pre> <p>Problem why it does not work for you with normal object because YII uses <code>get_object_vars</code> internally and it can't access private properties when it's in different scope. </p>
