在下面的代码中，命名有规律。$tpl是没有后缀名的，$tplfile是后缀为htm的模板文件，$objfile是后缀为php的缓存文件。

UCH里使用模板的流程是：

在php代码中获取动态数据，然后include_once template($tpl)

template函数解析模板文件$tplfile，返回缓存文件$objfile。

template函数中调用parse_template函数解析$tplfile，

$tplfile里有UCH定义的一套语法，在parse_template函数里可以看到，有 等。这些语法在parse_template中都会被替换成对应的函数，如readtemplate blocktags等，这些函数也都位于function_template.php中。

这里有点点纠结的就是，模板文件中可能还通过包含了其他的模板文件，所以在parse_template中要两次调用preg_replace，第一次读模板文件$tplfile所包含的子模板文件name，第二次是读子模板文件name中再包含的孙子模板文件。UCH中至多有3层模板包含关系，即父亲->儿子->孙子，所以不需要第三次调用preg_replace来读取孙子模板文件可能包含的重孙模板文件了。

template函数在function_common.php中定义

function template($name) {

global $_SCONFIG, $_SGLOBAL;

if(strexists($name,'/')) {

$tpl = $name;//$name是完整目录的情况

} else {

$tpl = "template/$_SCONFIG[template]/$name";

/*

$name只是一个文件名的情况，$tpl类似template/default/cp_blog或者template/blue/cp_blog

默认的模板风格是default，但是如果用户选择了其他风格，$_SCONFIG[template]就会变成blue之类的其他值

在首页的右下角可以选择模板风格

*/

}

$objfile = S_ROOT.'./data/tpl_cache/'.str_replace('/','_',$tpl).'.php';

/*

缓存文件名,$objfile类似data/tpl_cache/template_default_cp_blog.php或者data/tpl_cache/template_blue_cp_blog.php

if(!file_exists($objfile)) {

include_once(S_ROOT.'./source/function_template.php');

parse_template($tpl);

//如果缓存文件不存在，则对模板文件进行解析

}

return $objfile;

}

parse_template函数在function_template.php中定义

function parse_template($tpl) {

global $_SGLOBAL, $_SC, $_SCONFIG;

//包含模板

$_SGLOBAL['sub_tpls'] = array($tpl);

$tplfile = S_ROOT.'./'.$tpl.'.htm';

//read

if(!file_exists($tplfile)) {

$tplfile = str_replace('/'.$_SCONFIG['template'].'/', '/default/', $tplfile);

//如果非默认模板风格的某个模板文件不存在，那么就改用default风格的该模板文件

$template = sreadfile($tplfile);

//变量

$var_regexp = "((\\\$[a-zA-Z_\x7f-\xff][a-zA-Z0-9_\x7f-\xff]*)(\[[a-zA-Z0-9_\-\.\"\'\[\]\$\x7f-\xff]+\])*)";

/*

上面用红色显示的\是转义符，没用红色显示的\就还是反斜杠

但是一开始为什么要用三个\，我搞不明白。试验了一下，\\\$匹配的就是$，而改成\$却没能匹配模板文件里的变量名。这个我还没搞明白。

$var_regexp匹配变量名

[a-zA-Z_\x7f-\xff] 变量名以字母或下划线或汉字开头

\x7f-\xff这个让人非常困惑，到底是想匹配什么呢？难道是想匹配扩展ASCII码吗？0x7f-0xff确实是扩展ASCII码表的范围，但显然没人会用这些控制字符去当变量名。

我这个UCH是UTF-8版本的，从UCS-2（就是现在通用的Unicode）到UTF-8的编码方式如下：

UCS-2编码(16进制)

UTF-8 字节流(二进制)

0000 - 007F

0xxxxxxx

0080 - 07FF

110xxxxx 10xxxxxx

0800 - FFFF

1110xxxx 10xxxxxx 10xxxxxx

前面的0000-007F是兼容ASCII码的

汉字的unicode编码在0080-FFFF里，转换成UTF-8后的字节是

110xxxxx或10xxxxxx或1110xxxx，在0x01111111-0x11111111范围内，也即0x7f-0xff。

更精确地，这个匹配变量名开头的部分可以写成[a-zA-Z_\xc0-\xef],因为汉字的开始字节只可能是110xxxxx或1110xxxx，范围就是0xc0-0xdf和0xe0-0xef

[a-zA-Z0-9_\x7f-\xff]* 比变量名的开头字节的允许取值范围多了数字，和C语言是一样的，变量名不能以数字开头

更精确地，这里可以写成[a-zA-Z0-9_\x80-\xef]* 因为这里汉字的字节可能是110xxxxx或1110xxxx或10xxxxxx，比0xc0-0xef多了10xxxxxx，即0x80-0xbf，合起来就是0x80-0xef

(\[[a-zA-Z0-9_\-\.\"\'\[\]\$\x7f-\xff]+\])*

变量可能是数组形式的，如$name1[$name2]，\$[a-zA-Z_\x7f-\xff][a-zA-Z0-9_\x7f-\xff]*匹配了$name1，后面的[$name2]怎么匹配呢？我一开始以为是\[\$[a-zA-Z_\x7f-\xff][a-zA-Z0-9_\x7f-\xff]\],因为[]里面也应该是一个变量名。

但是变量可能是嵌套数组形式的，如$name1[$name2[$name3[$name4]]]，此时用\$[a-zA-Z_\x7f-\xff][a-zA-Z0-9_\x7f-\xff]来一个个匹配变量名明显不可行。所以只是用[]把可能的字符都框起来，希望程序员不要写太扯淡的变量名了。
