How to suppress Undefined index error?

Question

Before you suggest using isset or empty or array_key_exists -- I know.

I've inherited an old project with close to a million lines of code. I would like to enable E_NOTICE but I get flooded with messages. As a temporary solution I've suppressed just "undefined index" errors by doing this:

function _global_error_handler($level, $message, $filename, $line_no, $context) {
    if($level===E_NOTICE && substr($message,0,16)==='Undefined index:') return false; 

But I was hoping there would be some way to disable the notice altogether via an INI setting or something. I don't want the overhead of it calling the global error handler every time this happens.

No, there is no way to be more specific than the E_* constants, short of manually parsing the error condition as you currently are doing.

What I would suggest for now is to disable E_NOTICE errors. When you have the opportunity (which should be as soon as reasonably possible), enable them again and go through fixing as many as possible.
