在php中要传递参数有几种方法,今天我们就讲关于post get二种方法,post用得最多的是利用表单来传参数,get参数一般是url传值居多,下面我们举了二款实例.

post表单传递参数,代码如下:

<html>  
    <head>  
    </head>  
    <body>  
    <h3>search</h3>  
    <form action="c.php" method="post">  
    depart name:<input type="text" size=25 name="depart" value=""><br><br>  
    <input type="submit" name="submit" value="search">  
    </form>  
    </body>  
</html>
Copy after login

c.php页面,代码如下:

<?php  
    $depart=$_post["depart"];  
    $q = "select * from info where depart=&#39;$depart&#39;";  
?>
Copy after login

实例二get 方法传递参数,代码如下:

<a href="http://www.phprm.com/a.php?value=www.phprm.com">传get参数传</a>
