js怎么跟php结合使用

<script type="text/javascript">
 
 BUI.use('bui/grid',function (Grid) {
 var data = [//表单内容信息
 <?php
	foreach($slice_rows as $key=>$val){
	echo "{id:'".$val['id']."',imgpath:'".$val['imgpath']."',introduction:'".$val['introduction'].
 "',linkpath:'".$val['linkpath']."',date:'".$val['date']."'},";
	 }
	
	 echo "{id:'1112',imgpath:'李四',introduction:'this is a test',linkpath:'#',date:'date2'}";
	 ?>
	],
 
 grid = new Grid.SimpleGrid({
 render : '#grid', //显示Grid到此处
 width : 950, //设置宽度
 columns : [//表单头部信息
 {title:'编号',dataIndex:'id',width:80},
 {title:'图片路径',dataIndex:'imgpath',width:100},
	{title:'简介',dataIndex:'introduction',width:200},
	{title:'链接地址',dataIndex:'linkpath',width:100},
 {title:'上传日期',dataIndex:'date',width:100}
 ]
 });
 grid.render();
 grid.showData(data);
 });
 
</script>

<?php
	
	echo '<script type="text/javascript">';
	echo " BUI.use('bui/grid',function (Grid) {";
