PHP警告date(): It is not safe to rely on the system

 date_default_timezone_set("PRC");  或 ini_set('date.timezone','asiashanghai');

date.timezone = PRC。

<?php
$jsonText = array (
 0 => array (
  'id' => '1',
  'name' => '文本1'
 ),
 1 => array (
  'id' => '2',
  'name' => '文本2'
  )
) ;
 
echo json_encode($jsonText);
//[{"id":"1","name":""},{"id":"2","name":""}]
//可以看到汉字没有被转义都为空“”，这是因为json仅仅转义encoding编码(类似于:%B0%AE)，故上面语句应该先转换编码
?>

<?php
foreach ($jsonText as $key=>$value)
{
 $jsonText[$key]['name'] = urlencode($value['name']);
}
echo json_encode($jsonText);
?>
客户端处理

<script type="text/javascript">
function encodeTest(obj)
{
 $.ajax( {
  type : "GET",
  url : "< ?=$this->baseUrl?>/index/getajax",
  data : "c=" obj.value,
  success : function(json)
   {
       var json=eval(json);
       var testValue = '';
       $.each(json, function(k) {
                   testValue += decodeURI(json[k]['name']) ;
       });
 
       alert(testValue);
   }
 } )
 
}

</script>

<?php
foreach ($jsonText as $key=>$value)
{
 $jsonText[$key]['name'] = urlencode(iconv('gb2312', 'utf-8',$value['name']));
}
echo json_encode($json);
?>

查看输出结果为：

{“name”:”u4e2du6587u5b57u7b26u4e32″,”value”:”test”}

    $testJSON=array('name'=>'中文字符串','value'=>'test');
