How to call php files from static html, _PHP tutorial
Static html method of calling php files,
It seems that the php file cannot be called directly in the static page, but you can use the js calling method to call the php file. Of course, you can also use ajax to call the php file. Let me introduce it to you below:
Example A simple example to illustrate:
If you use the following call in page a.html, you can pass the action=test parameter to b.php.
Javascript code
There is this piece of PHP code in b.php:
<?php $action=$_GET['action']; echo "document.write('".$action."');n"; ?>
When the a.html file is executed, the b.php file will be called, and the output of the b.php file will be executed as a JS statement. The content is the value of the parameter action passed by JS, which is accepted in the PHP file. The value of the passed action.
The load function of jquery is a call that requests another file and loads it into the current DOM
1. Load a php file, which does not contain passed parameters
$("#myID").load("test.php");
2. Load a php file, which contains a passing parameter
$("#myID").load("test.php",{"name" : "Adam"});
3. Load a php file that contains multiple passed parameters. Note: Separate parameters with commas
$("#myID").load("test.php",{"name" : "Adam" ,"site":www.shouce.ren});
//The imported php file contains A passing parameter, similar to: test.php?name=Adam&site=www.shouce.ren
4. Load a php file that uses an array as a passing parameter
$("#myID").load("test.php",{'myinfo[]', ["Adam", www.shouce.ren});
//The imported php file contains a Array parameters are passed.
1 Call the PHP file using JS and get the value in php
Give a simple example to illustrate:
For example, in page a.html, use the following sentence to call:
<script type="text/javascript" src="b.php?action=test"></script> <script type="text/javascript" > alert(jstext); </script>
There is this piece of PHP code in b.php:
$action=$_GET['action']; //echo "var jstext='$action'"; //Output a JS statement, generate a JS variable, and assign the value to the PHP variable $ The value of action //echo "var jstext='aa'"; echo "var jstext="."'$action'"; ?>
When the a.html file is executed, the b.php file will be called, and the output of the b.php file will be executed as a JS statement, so a prompt box will pop up here with the value of the JS variable jstext. That is the value assigned to jstext in the PHP file.
Summary:
Use JS to call the file in HTML to call the PHP file, and the output of the PHP file will be used as JS code by the calling page.
2 php calls the value in js
There is such a piece of code in the z.php page:
$key=""; echo $key; ?>
3 php calls methods (functions) in js
< ;?php echo ""; ?>
4 JS calls PHP variables
(1)
$userId=100;
?> <script><br />var userId;<br />userId=document.getElementByIdx_x_x_x("userId").value;<br /> alert (userId);<br /></script>
(2)
$url = 'changed URL'; //Define variables
?>

var Y=,M=,D=;

6 The js and php written by yourself call each other
1.php content:
<?php //echo "<script LANGUAGE='javascript'>alert('$php变量');</script>"; //最简单的php调用js //echo "<a href=#><img style="max-width:90%"$fruit_pic_array[$i]' onMouseOver=’javascript:a();‘ alt="How to call php files from static html, _PHP tutorial" ></a>"; //echo "<a href='3.php'>aaaa</a>"; //php中超链接 //echo "<script type='text/javascript' language='javascript'>phpmake('PHP建站学习笔记网');</script>"; //有时候需要在PHP执行过程中,需要调用JavaScript自定义函数(验证时出错) echo "function ok(msg){alert(msg);}"; ?>

2.php content:

<SCRIPT Language = "JavaScript"> function func() { if(confirm("Are you OK with this?")) { this.location = "ok.php?action=ok"; } else { this.location = "ok.php?action=cancel"; } } </SCRIPT>

Session in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
