Smaty优点：1.代码分离 2.缓存技术使用步骤： 1.下载Smaty模板 2.将模板中那个lib文件夹复制到项目中(一般为根目录，并且重命名在此命名为Smarty)， 3.配置PHP 1.新建一个Smarty_inc.php文件 2.输入 Include_once("Smarty/Smarty.class.php");//包含Smarty类 $smarty=new Smarty();//实例化Smarty对象 //配置 <table border="1" cellpadding="0" cellspacing="0" valign="top" style="direction:ltr; border-collapse:collapse; border-style:solid; border-color:#A3A3A3; border-width:1pt; margin-left:.7076in"><tbody><tr><td style="border-style:solid; border-color:#A3A3A3; border-width:1pt; vertical-align:top; width:2.6611in; padding:4pt 4pt 4pt 4pt">$smarty->config_dir="Smaryt/Config_File.class.php";</td><td style="border-style:solid; border-color:#A3A3A3; border-width:1pt; vertical-align:top; width:3.0937in; padding:4pt 4pt 4pt 4pt">配置文件目录路径，一般不更改</td></tr><tr><td style="border-style:solid; border-color:#A3A3A3; border-width:1pt; vertical-align:top; width:2.6611in; padding:4pt 4pt 4pt 4pt">$smarty->caching=false;</td><td style="border-style:solid; border-color:#A3A3A3; border-width:1pt; vertical-align:top; width:3.0937in; padding:4pt 4pt 4pt 4pt">是否开启缓存</td></tr><tr><td style="border-style:solid; border-color:#A3A3A3; border-width:1pt; vertical-align:top; width:2.6611in; padding:4pt 4pt 4pt 4pt">$smarty->template_dir="./templates";</td><td style="border-style:solid; border-color:#A3A3A3; border-width:1pt; vertical-align:top; width:3.0937in; padding:4pt 4pt 4pt 4pt">设置模板目录，手动创建，./代表当前目录必须设置</td></tr><tr><td style="border-style:solid; border-color:#A3A3A3; border-width:1pt; vertical-align:top; width:2.6611in; padding:4pt 4pt 4pt 4pt">$samrty->complie_dir="./templates_c";</td><td style="border-style:solid; border-color:#A3A3A3; border-width:1pt; vertical-align:top; width:3.0937in; padding:4pt 4pt 4pt 4pt">设置编译目录，手动创建，必须设置</td></tr><tr><td style="border-style:solid; border-color:#A3A3A3; border-width:1pt; vertical-align:top; width:2.6611in; padding:4pt 4pt 4pt 4pt">$smarty->cache_dir="./smarty_cache";</td><td style="border-style:solid; border-color:#A3A3A3; border-width:1pt; vertical-align:top; width:3.0937in; padding:4pt 4pt 4pt 4pt">设置缓存目录</td></tr><tr><td style="border-style:solid; border-color:#A3A3A3; border-width:1pt; vertical-align:top; width:2.6611in; padding:4pt 4pt 4pt 4pt">$smarty->left_delimiter="{";和$smarty->right_delimiter="}";</td><td style="border-style:solid; border-color:#A3A3A3; border-width:1pt; vertical-align:top; width:3.0937in; padding:4pt 4pt 4pt 4pt">设置在HTML标志Smarty的开始和结束标签自定义也可以世{%和%}</td></tr></tbody></table> Smarty使用变量定义变量 $smarty->assign("模板变量","值/数组"); 将改变量应用到特定的模板中 $smarty->display("模板名"); Eg: ~~~ $smarty->assign("title","我的第一个smarty程序")； $smarty->display("index.html"); 在index.html中使用 <html> <head> <title>{$title}</title> </head> </html> ~~~ 上述一次只能访问一个变量那么**怎样循环访问多个变量呢**?** 要想访问多个变量必须用到数组定义 ~~~ $array={name->"jiangtong",name->"张三",name->"李四"} $smarty->assign($student,$name); $smarty->display("index.html"); ~~~ **在**index.html**中使用** <html> <head></head> <body>、 <table border="1" cellpadding="0" cellspacing="0" valign="top" style="direction:ltr; border-collapse:collapse; border-style:solid; border-color:#A3A3A3; border-width:1pt; margin-left:.3333in"><tbody><tr><td style="border-style:solid; border-color:#A3A3A3; border-width:1pt; vertical-align:top; width:2.7409in; padding:4pt 4pt 4pt 4pt">{section name="stuList" loop="$student"}</td><td style="border-style:solid; border-color:#A3A3A3; border-width:1pt; vertical-align:top; width:1.6715in; padding:4pt 4pt 4pt 4pt">loop代表循环那个数组</td></tr><tr><td style="border-style:solid; border-color:#A3A3A3; border-width:1pt; vertical-align:top; width:2.7409in; padding:4pt 4pt 4pt 4pt">{$student[stuList].name}</td><td style="border-style:solid; border-color:#A3A3A3; border-width:1pt; vertical-align:top; width:1.6715in; padding:4pt 4pt 4pt 4pt"> </td></tr><tr><td style="border-style:solid; border-color:#A3A3A3; border-width:1pt; vertical-align:top; width:2.7409in; padding:4pt 4pt 4pt 4pt"><sectionelse>//可以不写</td><td style="border-style:solid; border-color:#A3A3A3; border-width:1pt; vertical-align:top; width:1.6715in; padding:4pt 4pt 4pt 4pt"> </td></tr><tr><td style="border-style:solid; border-color:#A3A3A3; border-width:1pt; vertical-align:top; width:2.7409in; padding:4pt 4pt 4pt 4pt">{/section}</td><td style="border-style:solid; border-color:#A3A3A3; border-width:1pt; vertical-align:top; width:1.6715in; padding:4pt 4pt 4pt 4pt"> </td></tr></tbody></table> <body> </html> Smarty取出当前时间 {$smarty.now}
