What is the meaning of php?
PHP ("PHP: Hypertext Preprocessor", abbreviation for Hypertext Preprocessor) is a widely used open source multi-purpose scripting language that can be embedded into HTML. Especially suitable for web development.
The above is a simple answer, but what does it mean? Please see the following example:
Example An introductory example
<!DOCTYPE html>
<html>
<head>
<title>Example</title>
</head>
<body>
<?php
echo "Hi, I'm a PHP script!";
?>
</body>
</html>Please note the difference between this example and other scripts written in C or Perl language-compared to using a large number of commands to Writing a program to output HTML The difference is that a PHP page is just HTML with some code embedded in it to do something (in this case output "Hi, I'm a PHP script!"). PHP code is enclosed in special start and end characters 815b22acdbf9dab14aa760b8cd72f36d, making it possible to enter and exit "PHP mode".
Different from client-side JavaScript, PHP code runs on the server side. If you build code similar to the example above on the server, after running the script, the client will receive the results, but they will have no way of knowing how the code behind it works. You can even set up the web server to let PHP handle all HTML files, so the user has no way of knowing what the server is doing.
The biggest advantage of using PHP is that it is extremely simple for beginners, while also providing a variety of advanced features for professional programmers. Don’t be afraid when you see PHP’s long list of features. You can get started quickly, and you can write some simple scripts in just a few hours.
Although PHP is developed for the purpose of server-side scripting, in fact its functions are far from limited to this. Recommended learning: "PHP Video Tutorial"
