Let’s take a look at an example first
Output HTML tag (Recommended learning: PHP video tutorial)
<?php $name = "张三"; ?> <html> <head></head> <body> <p>你好，<?php echo $name; ?>先生。</p> </body> </html>
The output is as follows
你好，张三先生。
The value assigned to the variable $name will be expanded and displayed as part of the HTML.
It is also possible to assign HTML tags to variables and display them.
<?php $name = "张三"; ?> <html> <head></head> <body> <p>你好， <?php $span = "<span style='color:red'> $name 先生。</span>"; echo $span; ?> </p> </body> </html>
The output results are as follows:
你好，张三先生。
In the above results, Mr. Zhang San will be displayed in red.
The variable $span contains HTML tags. When echo is used to output, the label part is recognized as a normal HTML markup and displayed.
Form processing
By making the target of an HTML form a PHP file, you can use that PHP file to process the data sent from the form.
Create a form using HTML.
<html> <head></head> <body> <form action="form.php" method="post"> 名称: <input type="text" name="name" /><br> <input type="submit" /> </form> </body> </html>
Fill out this form and press the submit button to send the form data to form.php.
Output data from form
I will output the data sent from the form above.
For data sent using POST, you can get $_POST['Element Name'], and for data sent using GET, you can get $_GET['Element Name'].
Use echo output.
你好，<?php echo $_POST['name']; ?>先生。
Enter "Zhang San" in the above form and press the send button, it will be displayed as follows.
你好，张三先生。
