What are the delimiters for php server scripts?

The operating system of this tutorial: Windows10 system, PHP version 8.1.3, DELL G3 computer.

In PHP server scripts, delimiters are mainly used to identify the beginning and end of code blocks so that the server can parse and execute the script correctly. The following are several commonly used delimiters in PHP:

1. Start tag:

This is the most common start tag in PHP, used to identify the beginning of a PHP code block . After this tag, you can write arbitrary PHP code. For example:

echo "Hello, World!";

?>

2. Short tag:

The short tag is another type of start tag in PHP. It is relatively concise and can be modified through settings in the PHP configuration file. However, using short tags in PHP scripts is not recommended because they may conflict with tags from other languages. For example:

echo "Hello, World!";

?>

3. End tag: ?>

The end tag is used to identify the end of a PHP code block. After this tag, no more PHP code should be included. For example:

echo "Hello, World!";

?>

// No more PHP code can be written here

?>

It should be noted that when the PHP file only contains PHP code, there is usually no need to use the end tag. This is because the PHP parser automatically treats the end of the file as the end of the code block.

In addition, there are some special delimiters for embedding PHP code in HTML:

4. Starting tag:

5. End tag: //-->

The closing tag is used to end a block of PHP code embedded in an HTML comment. For example:

It should be noted that when using these special delimiter, you must ensure that the PHP parser can correctly identify and parse the PHP code, and the comment tags are not sent to the client.

To summarize, the commonly used delimiters in PHP server scripts are the opening tag (), and embedding PHP in HTML comments The opening tag () of the code. Choose appropriate delimiters to write and organize PHP scripts based on specific needs and best practices. If you have any further questions please feel free to let me know.
