List of common bitmask values for PHP errors?

Question

Can someone please provide a list of the numbers we need to use to configure php error reporting levels in an Apache vhost? I think they're called "bitmask"s or something, but I cant find a list of them anywhere.

ie in Apache:

php_value error_reporting x

What should x be if I want the equivalent of:

error_reporting(E_ERROR);

And since there's no reference on this anywhere online (that I can find), let's do the rest too!

E_ALL = x

E_NOTICE = y

E_WARNING = z

Answer 1

Is this what you're looking for ?

EDIT

The values listed in the table pointed to above are the ones that you want. You will note that with the exception of E_ALL they are all powers of 2. Each of the values corresponds to a bit position in an integer. Adding the values of these bit positions together gives the value that you want in your vhost definition e.g.

if you want error reporting for E_ERROR E_NOTICE and E_USER_WARNING

Constant            Value         Binary

E_ERROR               1                1
E_NOTICE              8             1000
E_USER_WARNING      512       1000000000

Total               521       1000001001                                 

So the value to use in your vhost php_value error_reporting directive would be 521.
