SQL server不支持utf8 php却用utf8的矛盾问题解决方法

核心代码

function convert2utf8($string)
  {
    return iconv("gbk","utf-8",$string);
  }
  function convert2gbk($string)
  {
    return iconv("utf-8","gbk",$string);
  }

当插入数据,或修改数据的时候,把utf-8,转为gbk,存入数据库。

当获取数据的时候,将数据转为utf-8。

这个方法在底层的数据中设计,上层调用即可。

<?php
class dao_dao extends Zend_Db_Table {

  public function returnDb(){
    return $db = &$this->getAdapter();

  public function getData($table,$where = false, $order = 'id ASC', $pagesize = false, $offset = false, $count = false, $from = false, $join = false, $group = false) {
    $db = &$this->getAdapter();
    $select = $db->select();
    
    if ($where && is_array($where)) {
      foreach ($where as $key => $val) {
        //print_r($where);
        if($val['type']==1){
          $select->where($key, $val['val']);
        }else{
          $select->orwhere($key, $val['val']);
        }
        
      }
