If an <A HREF="ref.errorfunc.html#errorfunc.constants" ><TT CLASS="constant" ><B >E_RECOVERABLE_ERROR</B ></TT ></A > is not handled, it will behave in the same way as <TT CLASS="constant" ><B >E_ERROR</B ></TT > behaves in all versions of PHP. Errors of this type are logged as <TT CLASS="literal" >Catchable fatal error</TT >. </P ><P > This change means that the value of the <TT CLASS="constant" ><B >E_ALL</B ></TT > <A HREF="ref.errorfunc.html#ini.error-reporting" >error_reporting</A > constant is now 6143, where the previous value was 2047. Because PHP constants have no meaning outside of PHP, in some cases the integer value is used instead so these will need to be adjusted. So for example if you are setting the error_reporting mode from either the <A HREF="ref.apache.html#apache.configuration" >httpd.conf</A > or the <TT CLASS="filename" >.htaccess</TT > files, you will need to adjust the value accordingly. The same applies if you use the numeric value rather than the constant in your PHP scripts. </P ><P > As a side-effect of a change made to prevent duplicate error messages when <A HREF="ref.errorfunc.html#ini.track-errors" >track_errors</A > is <TT CLASS="literal" >On</TT >, it is now necessary to return <TT CLASS="constant" ><B >FALSE</B ></TT > from your error handler in order to populate <A HREF="reserved.variables.html#reserved.variables.phperrormsg" >$php_errormsg</A >. This provides you fine-grain control over the levels of messages stored. </P ></DIV ><DIV CLASS="NAVFOOTER" ><HR ALIGN="LEFT" WIDTH="100%"><TABLE SUMMARY="Footer navigation table" WIDTH="100%" BORDER="0" CELLPADDING="0" CELLSPACING="0" ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" ><A HREF="migration52.newconf.html" ACCESSKEY="P" >上一页</A ></TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="index.html" ACCESSKEY="H" >起始页</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" ><A HREF="migration52.other.html" ACCESSKEY="N" >下一页</A ></TD ></TR ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" >New INI Configuration Directives</TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="migration52.html" ACCESSKEY="U" >上一级</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" >Other Enhancements</TD ></TR ></TABLE ></DIV ></BODY ></HTML >
