本文实例讲述了smarty自定义函数用法。分享给大家供大家参考，具体如下：
<?phprequire_once "smarty.config.php";//自定义一个函数//调用方法：<{test1 times="4" size="5" con="Hello,Liuyibao!" color="red"}>function test1($args){$str="";for($i=0;$i<$args['times'];$i++){$str.="<p style='font-size:{$args['size']}em;color:{$args['color']}'>{$args['con']}</p>";}return $str;}//自定义一个块方式函数//调用方法<{test1}><{/test1}>function test2($args,$con){$str="";for($i=0;$i<$args['times'];$i++){$str.="<p style='font-size:{$args['size']}em;color:{$args['color']}'>{$con}</p>";}return $str;}//定义一个计算方法function jisuan($args){switch($args['operate']){case "+" :$res=$args['num1']-$args['num2'];break;case "-" :$res=$args['num1']-$args['$num2'];break;case "*" :$res=$args['num1']*$args['$num2'];break;case "/" :$res=$args['num1']/$args['$num2'];break;}return $res;}//注册一下$smarty->register_function("liuyibao","test1");//注册块函数$smarty->register_block("liuyibao2","test2");//注册函数jisuan$smarty->register_function("jisuan","jisuan");//替换变量$smarty->display("function.tpl");?>
