php警告重定向 [英] php warning redirect

问题描述

我使用 snmp2_real_walk 函数.

$tmp = snmp2_real_walk($ip, '***'.$vlan, $title, 100000,10);

当 oid 正确且设备正常工作时，我会得到所需的输出.但我想处理警告:Invalid object identifier... 或 No response from 192.168.19.249... 或其他.我的问题是:如何将这些警告重定向到我的变量中?

When oid is correct and the device is working i get the desired output. But i want to handle warnings: Invalid object identifier... or No response from 192.168.19.249... or whatever. My problem is: how can i either redirect those warnings into my variable?

或者是否有其他函数显示这些警告?

or is there some another function which shows these warnings?

谢谢！

推荐答案

你也可以看看 set_error_handler为这种特定情况设置自己的错误处理程序，然后在进行函数调用后恢复错误处理程序.

You could also have a look at set_error_handler to set your own error handler for this specific case, and then restore the error handler after making the function call.
