需求：修改产品的group price的值(catalog_product_entity_group_price表value字段的值),
修改为如下形式:
41.78 => 41.95
55.88 => 55.95

//1.遍历所有产品
$sql = "SELECT * FROM catalog_product_entity_group_price";
$query = $handle->query($sql);
while ($row = $query->fetch()) {
$row = new Varien_Object($row);
$entity_id =  $row->getentity_id(); //产品id
$value = $row->getValue(); //value值也就是我们要的group price的值

//2.分割
$extArray = explode( '.' ,$value );
$newValue = $extArray[0].'.9500';
echo  $value.'====='.$newValue.'<br>';

//3.修改
$sql = "update catalog_product_entity_group_price set `value`=".$newValue."WHERE entity_id=".$entity_id;
