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;------解决方案--------------------
= heredoc 句法结构：
<br /><?php <br />$content = <<<FDIPZONE <br /><html> <br /><head> <br /><title>test</title> <br /></head> <br /><body> <br /><p><img src="/static/imghwm/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 $content; <br />?> <br />
參考：http://blog.csdn.net/fdipzone/article/details/24937669
------解决方案--------------------
這樣就可以了。
<br />$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 />

Dependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AMYou should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AMSelect DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
