This article mainly introduces the implementation of PHP obtaining form data and HTML embedding PHP scripts. It has a certain reference value. Now I share it with you. Friends in need can refer to it.

PHP accepts HTML When the form submits information, the submitted data will be saved in the global array. We can call the system-specific automatic global variable array to obtain these values.

Commonly used automatic global variables are as follows:

1. GET method

Function: Get the data submitted by get method

Format: $_GET["formelement"]

2. POST method

Function: Get the data submitted by post method

Format: $_POST["formelement"]

##3. REQUEST method

Function: Get data submitted in any way. The $_REQUEST automatic global variable contains all GET, POST, COOKIE and FILE data, if you don’t care about the data source.

Format: $_REQUEST["formelement"]

Check box, list box (the name is in the form of an array For example: "select[]", just use $_POST["select"] when getting its value)

<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>无标题文档</title>
</head>

<body>
<!--获取表单数据的两种方法-->
<!--post-->
<form method="post" action="8.3.php" name="form1">
 <table border="1" width="400" cellpadding="0" cellspacing="0">
 <tr>
  <td height="30"> 用户名:<input name="txtName" type="text" size="12">
  密码:<input name="txtPsd" type="password" size="12">
  <input type="submit" name="SubmitBtn" value="提交">
  </td>
 </tr>
 </table>
</form><br/>

<!--get URL的长度需要限定在1M范围内，否则会截取-->
<!--可以使用urlencode与urldecode对URL进行编解码-->
<form method="get" action="8.3.php" name="form2">
 <table border="1" width="400" cellpadding="0" cellspacing="0">
 <tr>
  <td width="400" height="30"> 订单号:<input name="txtFrame" type="text" size="12">
  <input type="submit" name="SubmitBtn">
  </td>
 </tr>
 </table>
</form>

<!--在Web页面中嵌入PHP脚本-->
<?php
  $strTxt = &#39;男&#39;;
?>
<input type="text" value="<?php echo "strTxt"; ?>">

</body>

<?php
  echo &#39;用户名: &#39;.$_POST["txtName"]." 密码：".$_POST[&#39;txtPsd&#39;];
  echo &#39;订单号:&#39;.$_GET["txtFrame"];
?>

</html>
