小弟我想在php中根据用户输入的参数在sql语句中建立表格

我想在php中根据用户输入的参数在sql语句中建立表格
比如我现在用$_GET[‘tablename’]来了用户的输入值,我想在php文件中用sql语句create一个名字叫$_GET[‘tablename’]的表格,请问
create table [tablename]这里的tablename如何表示呢这句sql语句才是正确的
我用 create table {. $_GET[‘tablename’]. }不能实现啊?
------解决方案--------------------

$sql = <<<SQL<br />create table {$_GET['tablename']}<br />...<br />SQL;
Copy after login


------解决方案--------------------
= <<heredoc 句法结构:<<<。在该运算符之后要提供一个标识符,然后换行。接下来是字符串本身,最后要用前面定义的标识符作为结束标志。


<br /><?php  <br />$content = <<<FDIPZONE  <br /><html>  <br /><head>  <br /><title>test</title>  <br /></head>  <br /><body>  <br /><p><img  src="/static/imghw/default1.png"  data-src="http://www.csdn.net/css/logo.png"  class="lazy"   alt="小弟我想在php中根据用户输入的参数在sql语句中建立表格" ></p>  <br /><p><a href='http://blog.csdn.net/fdipzone'>blog</a></p>  <br /></body>  <br /></html>  <br />FDIPZONE;  <br />  <br />echo $content;  <br />?>  <br />
Copy after login


參考:http://blog.csdn.net/fdipzone/article/details/24937669
------解决方案--------------------
這樣就可以了。

<br />$sql =<<<SQL<br />CREATE TABLE `{$_GET['tablename']}` (<br />  `id` int(10) unsigned NOT NULL auto_increment,<br />  `name` varchar(100) NOT NULL,<br />  `age` tinyint(4) unsigned NOT NULL,<br />  `addtime` datetime NOT NULL,<br />  PRIMARY KEY  (`id`)<br />)<br />SQL;<br /><br />mysql_query($sql) or die(mysql_error());<br />
Copy after login
