[CodeIgniter]建立自己的公用function

自己建立的類別函數可以存放在 application/libraries 資料夾


<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Myclass {

public function js_alert($str1,$str2='')
{ 
echo "<meta http-equiv=Content-Type content=text/html; charset=utf-8>";
if($str2=='')
{echo "<script>alert('$str1');history.go(-1);</script>";exit();}
else
{echo "<script>alert('$str1');location.href='$str2';</script>";exit();}
exit();
}
}

/* End of file Myclass.php */
