PHP将页面中点击数量高的链接进行高亮显示的方法,点击数量高亮显示

背景和需求

就好比说页面导航的左侧是分类,分类下面有很多链接。我现在想统计所有分类下面点击次数最多的一个,并把其颜色做特殊处理!

大致的数据结构如下:

{
  "content": [
    {
      "id": "1",
      "name": "htmldrive",
      "url": "http://www.htmldrive.net/",
      "cate": "前端开发",
      "clickpoint": "100"
    },
    {
      "id": "2",
      "name": "17素材网",
      "url": "http://www.17sucai.com/",
      "cate": "前端开发",
      "clickpoint": "151"
    },
    {
      "id": "3",
      "name": "阿里妈妈图标库",
      "url": "http://www.iconfont.cn/",
      "cate": "前端开发",
      "clickpoint": "2"
    },
    {
      "id": "53",
      "name": "Animate.css",
      "url": "http://www.haorooms.com/uploads/example/Animatecss/",
      "cate": "前端开发",
      "clickpoint": "21"
    },
    {
      "id": "55",
      "name": "Dafont",
      "url": "http://www.dafont.com/",
      "cate": "字体",
      "clickpoint": "1"
    }
 ]
}

如何对这些数据进行分类高亮显示呢?

方法和思路

最好的处理方式是在后端PHP中对齐进行处理。

思路:我们可以创建一个新的过渡数组,对原来的数组进行循环,创建一个分类的数组,然后把点击次数中的最大值和ID放到这个数组中。通过比较,获取分类中点击次数最多的ID和点击次数,然后把这个次数最多的ID放在一个新的数组中,循环原来的数据,通过inarray(),函数判断次数最多的ID是不是在这个数组当中,是的话,就给数据增加一个标示字段1,不是的话就是0。那么标示字段为1的就是分类中点击次数最多的。

调整之后输出的json是:

 {
    "content": [
      {
        "id": "1",
        "name": "htmldrive",
        "url": "http://www.htmldrive.net/",
        "cate": "前端开发",
        "clickpoint": "100",
       "max": 0
      },
      {
        "id": "2",
        "name": "17素材网",
        "url": "http://www.17sucai.com/",
        "cate": "前端开发",
        "clickpoint": "151",
        "max": 1
      },
      {
        "id": "3",
        "name": "阿里妈妈图标库",
        "url": "http://www.iconfont.cn/",
        "cate": "前端开发",
        "clickpoint": "2",
        "max": 0
      },
      {
        "id": "53",
        "name": "Animate.css",
        "url": "http://www.haorooms.com/uploads/example/Animatecss/",
        "cate": "前端开发",
        "clickpoint": "21",
        "max": 0
      },
      {
        "id": "55",
        "name": "Dafont",
        "url": "http://www.dafont.com/",
        "cate": "字体",
        "clickpoint": "1",
        "max": 0
      }
   ]
  }

php的代码如下:

  $sql = "select id,name,url,cate,clickpoint from commonwebsite order by id asc ";
  $res= $db->getAll($sql);
  $temp_arr = array();
  foreach ($res as $key => $value) {
  if(!isset($temp_arr[$value['cate']])){
   $temp_arr[$value['cate']] = array();
   $temp_arr[$value['cate']]['max'] = $value['clickpoint'];
   $temp_arr[$value['cate']]['id'] = $value['id'];
  }else{
   if($value['clickpoint']>$temp_arr[$value['cate']]['max']){
    $temp_arr[$value['cate']]['max'] = $value['clickpoint'];
    $temp_arr[$value['cate']]['id'] = $value['id'];
   }
  }
  }
 $temp_id = array(); //创建一个存放ID的临时数组
  foreach ($temp_arr as $val) {//循环之前创建的临时数组,存放分类和最多点击次数的
  $temp_id[] = $val['id']; //将点击次数最多的ID赋值给了临时数组
  }
   foreach ($res as $key => $vals) { //循环原来的数据
   if(in_array($vals['id'], $temp_id)){//如果次数最多的ID在原来的数组的ID中,那个加一个字段max并设置其值为1
    $res[$key]['max'] =1;
   }else{
    $res[$key]['max'] =0;//否则不是点击次数最多的,设置为0
   }
  }
  $result['content'] = $res;
    die(json_encode($result)); //json输出
  exit();

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
