Datasource string values with leading zeros are converted to Integer when parsing the dataValue field in PHP wrappers

Bug report

Datasource string values with leading zeros are converted to Integer when parsing the dataValue field. The issue is related to the following code in the wrappers, which returns the value without the leading zeros:

Reproduction of the problem

Use the following datasource setup with multicolumncombobox for example:

<?php
require_once '../lib/DataSourceResult.php';
require_once '../lib/Kendo/Autoload.php';
require_once '../include/header.php';
$multicolumncomboBox = new \Kendo\UI\MultiColumnComboBox('combobox');
$multicolumncomboBox->dataTextField('text')
         ->dataValueField('value')
         ->dataSource(array(
            array('text' => 'Item 1', 'value' => '01'),
            array('text' => 'Item 2', 'value' => '002'),
            array('text' => 'Item 3', 'value' => '099')
         ))
         ->addColumn(
            array('field' => 'text', 'title' => 'Text'),
            array('field' => 'value', 'title' => 'Value')
           )
         ->filter('startswith')
         ->attr('style', 'width: 100%;');
?>
<?php
echo $multicolumncomboBox->render();
?>
</div>

Open the dropdown.

Current behavior

The third value is 99

Expected/desired behavior

The third value is 099

note: the issue is caused by the internal usage of json_encode($value, JSON_NUMERIC_CHECK )
