如何在使用try catch时隐藏PHP错误

Question

I am doubt of PHP's try catch mechanism about why when l using try catch to process the error, but PHP still show the default error message

For example, l'm using PHP excel lib to parse the xls file, but l wanna to print a user friendly error output, like

{code:1, msg:"some error"}

So l do these:

    try {
        return $this->getJSON($fileName);
    }catch (Exception $e){
        $f = fopen('/' . trim(ROOT_DIR, '/\\') . '/file/Excel_error', 'wb');
        fwrite($f, $e);
        $split_content = "

-------------------------------------

";
        fwrite($f, $split_content);
        fclose($f);
        echo json_encode(array(
            "code" => 10000,
            "msg" => "Excel parse error",
            "files"=>null
        ));
    }

l want to log the error file and output my custom msg to front-end, but it doesn't work, When l trigger a error/warning or others, PHP still show the PHP Error/E_WARINING ... like follow screenshot

PS: l process the file in getJSON(), this function is my entrance.

You can change the error handling and logging section in the php.ini file. You could change the value of the error_reporting to E_ERROR to reduce the verbosity of the reporting and to avoid the warnings to be displayed.
