每5秒在php中使用jquery更改一次图片

<img id="thisImg" alt="img" src="images/img0.png"/>
<script type="text/javascript">
    $(function(){
        //prepare Your data array with img urls
        var dataArray=new Array();
        dataArray[0]="images/img1.png";
        dataArray[1]="images/img2.png";
        dataArray[2]="images/img3.png";
        dataArray[3]="images/img0.png";

        //start with id=0 after 5 seconds
        var thisId=0;

        window.setInterval(function(){
            $('#thisImg').attr('src',dataArray[thisId]);
            thisId++; //increment data array id
            if (thisId==3) thisId=0; //repeat from start
        },5000);        
    });
</script>
