TYPO3: how to supress deprecated warnings?

I tried modifying the php.ini file (error_reporting = E_ALL & ~E_DEPRECATED), but with no result. There's an older TYPO3 proje开发者_JS百科ct which I would like to examine, and all these warnings are really annoying..

Thanks in advance.

I'm not sure if this will work on your version of Typo3 but try setting the following options in the typo3conf/localconf.php or via the Install Tool.

$TYPO3_CONF_VARS['SYS']['displayErrors']    = '0'; // or '-1' to see other errors
$TYPO3_CONF_VARS['SYS']['errorHandlerErrors']     = 22519; // E_ALL ^ E_DEPRECATED ^ E_NOTICE (everything except deprecated-msgs and notices)
$TYPO3_CONF_VARS['SYS']['syslogErrorReporting']   = 22519; // E_ALL ^ E_DEPRECATED ^ E_NOTICE (everything except deprecated-msgs and notices)
$TYPO3_CONF_VARS['SYS']['belogErrorReporting']    = 22519; // E_ALL ^ E_DEPRECATED ^ E_NOTICE (everything except deprecated-msgs and notices)
