总结5.27php数组练习
<?php
$arr = [
['id'=>1,'title'=>'产品1','img'=>'images/tree_03.jpg'],
['id'=>2,'title'=>'产品2','img'=>'images/tree_05.jpg'],
['id'=>3,'title'=>'产品3','img'=>'images/tree_07.jpg'],
['id'=>4,'title'=>'产品4','img'=>'images/tree_12.jpg'],
['id'=>5,'title'=>'产品5','img'=>'images/tree_13.jpg'],
['id'=>6,'title'=>'产品6','img'=>'images/tree_14.png'],
]
?>
通过二维数组，设定每次循环的产品名称与图片
<?php
foreach($arr as $val){
?>
<li>
<a href="b.php?id=<?php echo $val['id']?>">
<p><img src="<?php echo $val['img']?>" alt=""></p>
<span><?php echo $val['title']?></span>
<div class="hide_con">
<em><img src="images/add.png" alt=""></em>
<i>查看详情</i>
</div>
</a>
</li>
<?php
}
?>
采用foreach循环，将二维数组中每个数组的元素打印到html区间的相应位置，再通过循环来形成多个框架取代li标签
<?php
if(isset($_GET['id'])){
$id = $_GET['id'];采用是否存在获取变量的方法来实现页面如何跳转，与前面目录跳转类似
}else{
header("location:/");
}
$arr = [];
switch($id){
case 1:
$arr = ['id'=>1,'title'=>'产品1','img'=>'images/tree_03.jpg'];
break;
case 2:
$arr = ['id'=>2,'title'=>'产品2','img'=>'images/tree_05.jpg'];
break;
case 3:
$arr = ['id'=>3,'title'=>'产品3','img'=>'images/tree_07.jpg'];
break;
case 4:
$arr = ['id'=>4,'title'=>'产品4','img'=>'images/tree_12.jpg'];
break;
case 5:
$arr = ['id'=>5,'title'=>'产品5','img'=>'images/tree_13.jpg'];
break;
case 6:
$arr = ['id'=>6,'title'=>'产品6','img'=>'images/tree_14.png'];
break;
}采用switch判断给数组添加设置元素来确定跳转后页面的内容
?>
<div class="l_assay_img fl">
<img src="<?php echo $arr['img']?>" alt="">
</div>
<div class="r_assay_intro fr">
<h2><?php echo $arr['title']?></h2>
