What is 22527 in error_reporting 22527 of phpinfo
问题 In my local dev env, I use PHP Version 5.3.3-1ubuntu9.2. Now when I see error_reporting, the value is 22527. What is 22527? I checked http://www.php.net/manual/en/errorfunc.constants.php, but I could not find the number. Could anyone tell me what it is? Do I need to change it to E_ALL | E_STRICT ? Thanks in advance. 回答1: This value is actually bitmap mask, a sum of constants. So, 22527 is 16384 E_USER_DEPRECATED + 4096 E_RECOVERABLE_ERROR + etc... In your case it's E_ALL & ~E_DEPRECATED , it
