php 過濾英文標點符號 過濾中文標點符號 代碼
復制代碼 代碼如下:
function filter_mark($text){
if(trim($text)=='')return '';
$text=preg_replace("/[[:punct:]\s]/",' ',$text);
$text=urlencode($text);
$text=preg_replace("/(%7E|%60|%21|%40|%23|%24|%25|%5E|%26|%27|%2A|%28|%29|%2B|%7C|%5C|%3D|\-|_|%5B|%5D|%7D|%7B|%3B|%22|%3A|%3F|%3E|%3C|%2C|\.|%2F|%A3%BF|%A1%B7|%A1%B6|%A1%A2|%A1%A3|%A3%AC|%7D|%A1%B0|%A3%BA|%A3%BB|%A1%AE|%A1%AF|%A1%B1|%A3%FC|%A3%BD|%A1%AA|%A3%A9|%A3%A8|%A1%AD|%A3%A4|%A1%A4|%A3%A1|%E3%80%82|%EF%BC%81|%EF%BC%8C|%EF%BC%9B|%EF%BC%9F|%EF%BC%9A|%E3%80%81|%E2%80%A6%E2%80%A6|%E2%80%9D|%E2%80%9C|%E2%80%98|%E2%80%99|%EF%BD%9E|%EF%BC%8E|%EF%BC%88)+/",' ',$text);
$text=urldecode($text);
return trim($text);
}
我們在做數據采集或者數據驗證過程中，經常需要做一些特殊的數據處理，如去除中英文標點符號，參考了網上的方法，比較靠譜的php去除中英文代碼如下：
<?php
$keyword="好‘。，好學習PHP！！！";
$keyword=urlencode($keyword);//將關鍵字編碼
$keyword=preg_replace("/(%7E|%60|%21|%40|%23|%24|%25|%5E|%26|%27|%2A|%28|%29|%2B|%7C|%5C|%3D|\-|_|%5B|%5D|%7D|%7B|%3B|%22|%3A|%3F|%3E|%3C|%2C|\.|%2F|%A3%BF|%A1%B7|%A1%B6|%A1%A2|%A1%A3|%A3%AC|%7D|%A1%B0|%A3%BA|%A3%BB|%A1%AE|%A1%AF|%A1%B1|%A3%FC|%A3%BD|%A1%AA|%A3%A9|%A3%A8|%A1%AD|%A3%A4|%A1%A4|%A3%A1|%E3%80%82|%EF%BC%81|%EF%BC%8C|%EF%BC%9B|%EF%BC%9F|%EF%BC%9A|%E3%80%81|%E2%80%A6%E2%80%A6|%E2%80%9D|%E2%80%9C|%E2%80%98|%E2%80%99)+/",'',$keyword);
$keyword=urldecode($keyword);//將過濾後的關鍵字解碼
echo $keyword;
輸出結果：
好好學習PHP
