The default value does not show <constant>E_NOTICE</constant> level
errors. You may want to show them during development.
In PHP 4 the default value does not show <constant>E_NOTICE</constant>
level errors. You may want to show them during development.
</para>
<note>
<para>Enabling <constant>E_NOTICE</constant> during development has
some benefits. For debugging purposes: NOTICE messages will warn you
about possibls bugs in your code. For example, use of unassigned values
are warned. It is extremely useful to find typos and
to save time for debugging. NOTICE messages will warn you about bad style.
For example, $arr[item] is better to be written as $arr['item'] since
PHP tries to treat "item" as constant. If it is not a constant, PHP assumes
it is a string index for the array.

<para>
In PHP 4, the default setting is
<literal>E_ALL &amp; ~E_NOTICE</literal>, meaning to display all errors
and warnings which are not E_NOTICE-level. In PHP 3, the default
setting is <literal>(E_ERROR | E_WARNING | E_PARSE)</literal>,
In PHP 3, the default setting is
<literal>(E_ERROR | E_WARNING | E_PARSE)</literal>,
meaning the same thing. Note, however, that since constants are not
supported in PHP 3's <filename>php3.ini</filename>, the error_reporting
setting there must be numeric; hence, it is <literal>7</literal>.
