本代码演示了如果不通过表单把信息直接提交到post信息里,非常有用
form.html
<form action="show.php" method="post">
    Enter Your Name: <input type="text" name="myName"><br>
    <input type="submit" name="submit" value="Submit">
</form>
show.php
<?php 
    // Get users input from the form and display it 
    echo '<div>Hello <b>'.$_POST['myName'].'</b></div>'; 
    // $_POST - This means it comes from a post method from a form 
    // myName is the name of the field that we want to retrieve from the form 
?>
