windows项目迁移到linux中。有很多文件名字是中文。写个脚本批量改名。
$a = "<a>河蟹社会afeowahgieawhjozf候蛇fawgwea维稳aghoiawghowi我日</a>"; $result = preg_replace('/([\x80-\xff]*)/i','',$a); var_dump($result);
2. [代码][php]代码
<?php try { $hostname = "localhost"; $dbname = "xxxx"; $username = "root"; $pw = "xxxx"; $pdo = new pdo ("mysql:host=$hostname;dbname=$dbname", "$username", "$pw"); $db->query("set names utf-8"); } catch (pdoexception $e) { echo "failed to get db handle: " . $e -> getmessage() . "\n"; exit; } $query = $pdo -> prepare("select id,store_image from store"); $query -> execute(); for($i = 0; $row = $query -> fetch(); $i++) { $new_file = preg_replace('/([\x80-\xff]*)/i', '',$row['store_image']); $id=$row['id']; $sql="update store set store_image='$new_file' where id=$id"; $pdo->exec($sql); } /* $it = new recursivedirectoryiterator("./avatar"); foreach(new recursiveiteratoriterator($it) as $file) { echo $file . "\n"; $new_file = preg_replace('/([\x80-\xff]*)/i', '', $file); rename($file, $new_file); } */
以上就是php字符串去掉中文的内容。
