1、PHP實現(xiàn)Javascript中的escape及unescape函數(shù)代碼分享_ 這篇文章主要介紹了PHP實現(xiàn)Javascript中的escape及unescape函數(shù)代碼分享,本文給出兩個實現(xiàn)版本,需要的伴侶可以參考下 這個類相當(dāng)好用.作用么,PHP做JSON傳遞GBK字符,比如中文,日文,韓文神馬的Unicode最合適不過了. ?php classcoding /仿照J(rèn)AVASCRIPT的ESCAPE和UNESCAPE函數(shù)的功能 functionunescape($str) $text=preg_replace_callback(/%u0-9A-Za-z4/,array( $this, to
