批量提取TXT存文本内容的第一张图片设为标题图片
好久没分享了,直接上代码?
保存成PHP文件放到/e/extend/新建目录/文件名.php <?php
require('../../class/connect.php'); //引入数据库配置文件和公共函数文件
require('../../class/db_sql.php'); //引入数据库操作文件
$link=db_connect(); //连接MYSQL
$empire=new mysqlquery(); //声明数据库操作类
$editor=1; //声明目录层次
//$goodid=intval($_GET['id']);
$cl=intval($_GET['classid']);
$sql=$empire->query("select * from phome_ecms_news where classid={$cl} order by id");
while($r=$empire->fetch($sql)){
$pagetexturl=ECMS_PATH."/d/txt/".$r[newstext].".php";
$text=ReadFiletext($pagetexturl);
$text=substr($text,12);//去除exit
$nr=stripslashes($text); //册除反
$pattern = "/.*src="([^^]*?)".*/i"; //正则
//$pattern ='/<img.+src="?(.+.(jpg|gif|bmp|bnp|png))"?.+>/i';
preg_match_all($pattern,$nr,$matches);
if(count($matches[1])>=1){
$diyfpic=$matches[1][0];
}else{
$diyfpic=$r['titlepic'];
}
$empire->query("update phome_ecms_news set titlepic='$diyfpic' where id=$r[id] limit 1");
}
db_close(); //关闭MYSQL链接
$empire=null; //注消操作类变量
