本文介紹了PHP學習：PHP將頁面中點擊數量高的鏈接進行高亮顯示的方法，希望對您有用。如果有疑問，可以聯(lián)系我們。
PHP實戰(zhàn)背景和需求
PHP實戰(zhàn)就好比說頁面導航的左側是分類,分類下面有很多鏈接.我現在想統(tǒng)計所有分類下面點擊次數最多的一個,并把其顏色做特殊處理!
PHP實戰(zhàn)大致的數據結構如下：
PHP實戰(zhàn)
{
"content": [
{
"id": "1",
"name": "htmldrive",
"url": "http://www.htmldrive.net/",
"cate": "前端開發(fā)",
"clickpoint": "100"
},
{
"id": "2",
"name": "17素材網",
"url": "http://www.17sucai.com/",
"cate": "前端開發(fā)",
"clickpoint": "151"
},
{
"id": "3",
"name": "阿里媽媽圖標庫",
"url": "http://www.iconfont.cn/",
"cate": "前端開發(fā)",
"clickpoint": "2"
},
{
"id": "53",
"name": "Animate.css",
"url": "http://www.haorooms.com/uploads/example/Animatecss/",
"cate": "前端開發(fā)",
"clickpoint": "21"
},
{
"id": "55",
"name": "Dafont",
"url": "http://www.dafont.com/",
"cate": "字體",
"clickpoint": "1"
}
]
}
PHP實戰(zhàn)方法和思路
PHP實戰(zhàn)最好的處理方式是在后端PHP中對齊進行處理.
PHP實戰(zhàn)思路：我們可以創(chuàng)建一個新的過渡數組,對原來的數組進行循環(huán),創(chuàng)建一個分類的數組,然后把點擊次數中的最大值和ID放到這個數組中.通過比較,獲取分類中點擊次數最多的ID和點擊次數,然后把這個次數最多的ID放在一個新的數組中,循環(huán)原來的數據,通過inarray(),函數判斷次數最多的ID是不是在這個數組當中,是的話,就給數據增加一個標示字段1,不是的話就是0.那么標示字段為1的就是分類中點擊次數最多的.
PHP實戰(zhàn)調整之后輸出的json是：
PHP實戰(zhàn)?
PHP實戰(zhàn)
{
"content": [
{
"id": "1",
"name": "htmldrive",
"url": "http://www.htmldrive.net/",
"cate": "前端開發(fā)",
"clickpoint": "100",
"max": 0
},
{
"id": "2",
"name": "17素材網",
"url": "http://www.17sucai.com/",
"cate": "前端開發(fā)",
"clickpoint": "151",
"max": 1
},
{
"id": "3",
"name": "阿里媽媽圖標庫",
"url": "http://www.iconfont.cn/",
"cate": "前端開發(fā)",
"clickpoint": "2",
"max": 0
},
{
"id": "53",
"name": "Animate.css",
"url": "http://www.haorooms.com/uploads/example/Animatecss/",
"cate": "前端開發(fā)",
"clickpoint": "21",
"max": 0
},
{
"id": "55",
"name": "Dafont",
"url": "http://www.dafont.com/",
"cate": "字體",
"clickpoint": "1",
"max": 0
}
]
}
PHP實戰(zhàn)php的代碼如下：
PHP實戰(zhàn)
$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'];
}
}
}
$temp_id = array(); //創(chuàng)建一個存放ID的臨時數組
foreach ($temp_arr as $val) {//循環(huán)之前創(chuàng)建的臨時數組,存放分類和最多點擊次數的
$temp_id[] = $val['id']; //將點擊次數最多的ID賦值給了臨時數組
}
foreach ($res as $key => $vals) { //循環(huán)原來的數據
if(in_array($vals['id'], $temp_id)){//如果次數最多的ID在原來的數組的ID中,那個加一個字段max并設置其值為1
$res[$key]['max'] =1;
}else{
$res[$key]['max'] =0;//否則不是點擊次數最多的,設置為0
}
}
$result['content'] = $res;
die(json_encode($result)); //json輸出
exit();
