Whether or not to populate the "object" index.
Since 5.3.6, this parameter is a bitmask for the following options:
<table>
<title><function>debug_backtrace</function> options</title>
<tgroup cols="2">
<tbody>
<row>
<entry>DEBUG_BACKTRACE_PROVIDE_OBJECT</entry>
<entry>
Whether or not to populate the "object" index.
</entry>
</row>
<row>
<entry>DEBUG_BACKTRACE_IGNORE_ARGS</entry>
<entry>
Whether or not to omit the "args" index and thus all the method arguments to
to save memory.
</entry>
</row>
</tbody>
</tgroup>
</table>
Before 5.3.6, only value recognized is &true; or &false;, which is the same as
setting and unsetting <constant>DEBUG_BACKTRACE_PROVIDE_OBJECT</constant> option.
