strtr 函数居然出现 Catchable fatal error

错误提示:


Catchable fatal error: Object of class variant could not be converted to string in D:wwwphpnowhtdocsxmlincxmlclass.php on line 160

160行代码: return $tab1.strtr($content,array('>'=>''>','&'=>'&','"'=>'"',"'"=>'''));


复制代码160行周围代码 function encode($content,$type='Element',$tab1='',$br='') { if($type=='Element') { return $tab1.strtr($content,array('>'=>''>','&'=>'&','"'=>'"',"'"=>''')); }elseif($type=='CDATA') { return '',']] >',$content).$br.']]>'; } }


复制代码重来没遇到过。
我记忆中只有php+access读取时会出现这样的问题。
在网上搜索了2小时,中文 英文全找了。没找到一点蛛丝马迹


类的全部代码见:

能再具体点吗?没听明白

看错误提示就已经很明白了,在php5中不能直接将对象输出为字符串,如果要实现这样的功能需要在对象的基类当中实现__tostring()方法.
也就是说在楼主的代码中$content就是这样的一个对象

C++ Function Exception Advanced: Customized Error Handling C++ Function Exception Advanced: Customized Error Handling May 01, 2024 pm 06:39 PM

Exception handling in C++ can be enhanced through custom exception classes that provide specific error messages, contextual information, and perform custom actions based on the error type. Define an exception class inherited from std::exception to provide specific error information. Use the throw keyword to throw a custom exception. Use dynamic_cast in a try-catch block to convert the caught exception to a custom exception type. In the actual case, the open_file function throws a FileNotFoundException exception. Catching and handling the exception can provide a more specific error message.
