Numeric values of error reporting levels

Question

I\'m checking the configuration of my PHP server and I need to set the following parameter as follows:

error_reporting set to E_ALL & ~E_NOTICE

Answer 1

From the page we have:

• E_ALL has the value 30719 in PHP 5.3.x, 6143 in PHP 5.2.x, 2047 previously

• E_NOTICE has the value 8

Looks like you are using PHP 5.2.x

Now If you do E_ALL & ~E_NOTICE Which is bitwise complement of E_NOTICE followed by bitwise anding with E_ALL we get

6143 & (~8) = 6135
