去除內容多餘樣式php函式
阿新 • • 發佈：2022-05-13
今天給客戶做百度小程式，出現數據庫裡面有多餘的樣式，比如style=""裡面內容，小程式前端又不好過濾，又不能去資料庫裡面替換，只能後端過濾多餘樣式進行排版。
程式碼附上：
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 |
function KillStyle($content)
{
$content = preg_replace("/STYLE=.+?['|\"]/i",'',$content);//去除樣式
$content = preg_replace("/style=.+?['|\"]/i",'',$content);//去除樣式
$content = preg_replace("/class=.+?['|\"]/i",'',$content);//去除樣式
$content = preg_replace("/id=.+?['|\"]/i",'',$content);//去除樣式
$content = preg_replace("/class=.+?['|\"]/i",'',$content);//去除樣式
$content = preg_replace("/id=.+?['|\"]/i",'',$content);//去除樣式
$content= preg_replace("/lang=.+?['|\"]/i",'',$content);//去除樣式

$content = preg_replace("/border=.+?['|\"]/i",'',$content);//去除樣式
$content = preg_replace("/face=.+?['|\"]/i",'',$content);//去除樣式
$content = preg_replace("/face=.+?['|\"]/",'',$content);//去除樣式只允許小寫正則匹配沒有帶 i 引數
$content = preg_replace("/<a[^>]*>/i", "", $content);
$content = preg_replace("/<\/a>/i", "", $content);
$content = preg_replace("/<div[^>]*>/i", "<p>", $content);

$content = preg_replace("/<(script.*?)>(.*?)<(\/script.*?)>/si","",$content); //過濾script標籤
$content = preg_replace("/<(em.*?)>(.*?)<(\/em.*?)>/si","",$content); //過濾script標籤
return $content;
