<p>The interaction between PHP and Web pages is an important means to realize the interaction between PHP websites and users. This article mainly introduces the use of PHP as a server to interact with the web front-end interface. It has certain reference value. Interested friends can refer to it.

<p>The interaction between PHP and Web pages is an important means to realize the interaction between PHP websites and users. I hope that scholars who read this article will first check out the basic knowledge of PHP, because I will use this thing today, so learn it now and sell it now. The basic knowledge of the PHP server will be updated later!

<p>1. First of all, you There needs to be an interface. Here I will use a simple interface developed by my project to explain it! Project confidentiality, please do not **, you understand!

<p>htmlcode and interface

<p> bc5574f69a0cba105bc93bd3dc13c4ecea444e6a14303e8217bef847d47d859bThe li part of the code above actually has eight implementations of this interface.

<p>

<p>Because the li codes are all the same, I won’t list them one by one. Just everyone understands.

<p>ok Everyone here understands ;The following is the js code for interaction using ajax

<p>Add a js code block below

<pre name="code" class="javascript"><script type="text/javascript"> 
  var str=""; 
  $.ajax({ 
    type:"post", 
    url:"postDemo.php", 
    data:{ 
      "code":"201", 
      "user":"admin" 
    }, 
    success:function(data){ 
      var result=eval("("+data+")"); 
      alert(data); 
      for(var i=0;i<result.length;i++){ 
        if ((i+1)%4){ 
          var str = "<li class=&#39;hot_sale_li left&#39; >" + 
              "<p class=&#39;pic&#39;><a style=&#39;width:260px;height:172px;&#39; href=&#39;" + result[i].titleURL + "&#39; title=&#39;维多利陶瓷 自然石系列&#39;><img style=&#39;width:260px;height:172px;&#39; alt=&#39;" + result[i].title + "&#39; src=&#39;" + result[i].imgURL + "&#39; /></a></p>" + 
              "<p class=&#39;tit&#39;><a href=&#39;" + result[i].titleURL + "&#39; title=&#39;" + result[i].title + "&#39;>" + result[i].title + "</a></p>" + 
              "<p class=&#39;price&#39;><span class=&#39;right&#39;>预订：<b class=&#39;yd_num&#39;>" + result[i].number + "</b>件</span><span class=&#39;bx_price&#39;>￥" + result[i].Nprice + "</span><span class=&#39;store_price&#39;>￥" + result[i].Oprice + "</span></p> </li>" 
 
        } 
        else { 
// 
          var str = "<li class=&#39;hot_sale_li left&#39;style=&#39;margin-right: 0px&#39; >" + 
              "<p class=&#39;pic&#39;><a style=&#39;width:260px;height:172px;&#39; href=&#39;" + result[i].titleURL + "&#39; title=&#39;维多利陶瓷 自然石系列&#39;><img style=&#39;width:260px;height:172px;&#39; alt=&#39;" + result[i].title + "&#39; src=&#39;" + result[i].imgURL + "&#39; /></a></p>" + 
              "<p class=&#39;tit&#39;><a href=&#39;" + result[i].titleURL + "&#39; title=&#39;" + result[i].title + "&#39;>" + result[i].title + "</a></p>" + 
              "<p class=&#39;price&#39;><span class=&#39;right&#39;>预订：<b class=&#39;yd_num&#39;>" + result[i].number + "</b>件</span><span class=&#39;bx_price&#39;>￥" + result[i].Nprice + "</span><span class=&#39;store_price&#39;>￥" + result[i].Oprice + "</span></p> </li>" 
 
        } 
        $(" .index_hot_sale #hot_sale").append(str); 
//       var oneTitle = result[i].title; 
//        $(".hot_sale_ul li:eq("+i+") a").attr("title",result[i].title); 
//        $(".hot_sale_ul li:eq("+i+") a").attr("title",result[i].title); 
 
      } 
    } 
  }) 
</script>
<p>

<p>
<p>上面的ajax的几个属性大家映带都懂 我简单说一下 type就是提交的方式 一共有post和get两种 我用的是post

<p>url就是服务器php的路径就是提交数据到的地址,data就是我们提交的数据,就是进行向服务器进行提交,然后服务器代码就是以下代码:

<p>

<p>
<?php</p>/** 
 * Created by PhpStorm. 
 * User: Administrator 
 * Date: 2016-7-15 
 * Time: 17:28 
 */ 
include "data.php"; 
if($_POST["code"]==201 && $_POST["user"]=="admin"){ 
//  echo json_encode(array("code"=>111)) ; 
  echo json_encode($hotSale); 
}else{ 
  echo json_encode(array("code"=>402)); 
  echo json_encode($hotSale); 
}
<p>

<p>The php file included by the server code is a php file that stores data. The code will be attached below; let me explain this simple server-side code

if($_POST["code"]==201 && $_POST["user"]=="admin"){ 
//  echo json_encode(array("code"=>111)) ; 
  echo json_encode($hotSale); 
}
<p>

<p>This judgment is based on the data sent from the client. If the code and user are correct, the data will be returned to you. If not, return 

else{ 
  echo json_encode(array("code"=>402)); 
  echo json_encode($hotSale); 
}
<p>

<p>This was decided upon during development with colleagues on the server side

<p> Let me talk about the correct time to return The data

<pre name="code" class="php">echo json_encode($hotSale);
<p>

<p> is the sentence echo. Everyone knows that it is a keyword in php. json_encode is to get us to load data.php
is This

<p>这里面就是所有的服务器提供的数据 然后进行获取那个数组
<p>$hotSale;
<p>然后传到我们html的ajax的data里面即使这个:
<p>


<span style="font-family: Arial, Helvetica, sans-serif;"></span><pre name="code" class="html">success:function(data){ 
      var result=eval("("+data+")"); 
      alert(data);
<p>

<p>This is inside the function funcation() that is executed when ajax is successfully obtained. The data of our array is obtained. In fact, it is a json file, but we still need to convert it to the array format. 
f8293c9a95b2c800a98c9e08a8fed1e6494c0df226525cc046cf4930a65bbd6fea444e6a14303e8217bef847d47d859bvar result=eval("(" data ")");This sentence is to convert it into a real array array that we are familiar with;
 

<p>Then we need eight pieces of data to traverse


<pre name="code" class="html">for(var i=0;i<result.length;i++){      
          var str = "<li class=&#39;hot_sale_li left&#39; >" + 
              "<p class=&#39;pic&#39;><a style=&#39;width:260px;height:172px;&#39; href=&#39;" + result[i].titleURL + "&#39; title=&#39;维多利陶瓷 自然石系列&#39;><img style=&#39;width:260px;height:172px;&#39; alt=&#39;" + result[i].title + "&#39; src=&#39;" + result[i].imgURL + "&#39; /></a></p>" + 
              "<p class=&#39;tit&#39;><a href=&#39;" + result[i].titleURL + "&#39; title=&#39;" + result[i].title + "&#39;>" + result[i].title + "</a></p>" + 
              "<p class=&#39;price&#39;><span class=&#39;right&#39;>预订：<b class=&#39;yd_num&#39;>" + result[i].number + "</b>件</span><span class=&#39;bx_price&#39;>￥" + result[i].Nprice + "</span><span class=&#39;store_price&#39;>￥" + result[i].Oprice + "</span></p> </li>" 
 
        }
<p>

<p>result.length is our maximum length,

<p>After the final traversal, eight items will be output; but someone must ask you how to load the array passed from the server into HTML; let’s explain the content in the var str above: 


<pre name="code" class="html" style="font-family: Arial, Helvetica, sans-serif;">var str = "<li class=&#39;hot_sale_li left&#39; >" + 
              "<p class=&#39;pic&#39;><a style=&#39;width:260px;height:172px;&#39; href=&#39;" + result[i].titleURL + "&#39; title=&#39;维多利陶瓷 自然石系列&#39;><img style=&#39;width:260px;height:172px;&#39; alt=&#39;" + result[i].title + "&#39; src=&#39;" + result[i].imgURL + "&#39; /></a></p>" + 
              "<p class=&#39;tit&#39;><a href=&#39;" + result[i].titleURL + "&#39; title=&#39;" + result[i].title + "&#39;>" + result[i].title + "</a></p>" + 
              "<p class=&#39;price&#39;><span class=&#39;right&#39;>预订：<b class=&#39;yd_num&#39;>" + result[i].number + "</b>件</span><span class=&#39;bx_price&#39;>￥" + result[i].Nprice + "</span><span class=&#39;store_price&#39;>￥" + result[i].Oprice + "</span></p> </li>" 
 
        }
<p>

<p>You can see that this is a custom array and then add a "" to each line. Everyone understands that this is a link in js Method; the data replacement inside is 
result[i].XXX; i is the traversed data. Each different i gets different data from the server json because it can be used to obtain it after it is converted into an array. ;
XXX refers to each array key, to get the value inside and put it into the attribute, and then write this html!!!

<p>The above is the entire content of this article, I hope it will be helpful to everyone's study.
