If it has changed, it recompiles that template. If the template has not been compiled, it will compile regardless of this setting. By default this variable is set to <TT CLASS="constant" >TRUE</TT >. </P ><P >Once an application is put into production (ie the templates won't be changing), the compile check step is no longer needed. Be sure to set <TT CLASS="parameter" ><I >$compile_check</I ></TT > to <TT CLASS="constant" >FALSE</TT > for maximal performance. Note that if you change this to <TT CLASS="constant" >FALSE</TT > and a template file is changed, you will *not* see the change since the template will not get recompiled. If <A HREF="variable.caching.html" ><TT CLASS="parameter" ><I >$caching</I ></TT ></A > is enabled and <TT CLASS="parameter" ><I >$compile_check</I ></TT > is enabled, then the cache files will get regenerated if an involved template file or config file was updated.
