模板不能动态包含

像这样<!--{template template/default/course/$space[school]}-->

因为执行解析模板时，先解析

$template = preg_replace("/\<\!\-\-\{template\s+([a-z0-9_\/]+)\}\-\-\>/ie", "readtemplate('\\1')", $template);

表达式中不允许存在$符号

function parse_template($tpl) {
 global $_SGLOBAL, $_SC, $_SCONFIG;

//包含模板
 $_SGLOBAL['sub_tpls'] = array($tpl);

$tplfile = S_ROOT.'./'.$tpl.'.htm';
 $objfile = S_ROOT.'./data/tpl_cache/'.str_replace('/','_',$tpl).'.php';
 
 //read
 if(!file_exists($tplfile)) {
  $tplfile = str_replace('/'.$_SCONFIG['template'].'/', '/default/', $tplfile);
 }
 $template = sreadfile($tplfile);
 if(empty($template)) {
  exit("Template file : $tplfile Not found or have no access!");
 }
