==Logging & Tracing==

===Pass error messages from PHP into virtuoso.log===

You can add the following entries to your php.ini file so that messages from php code appear in the virtuoso.log file:

{{{
	[Virtuoso]
	virtuoso.logging = On
	virtuoso.local_dsn = Local Virtuoso
	virtuoso.allow_dba = 0
}}}
