How to test whether the php environment is set up

With the development of the Internet, PHP has become one of the most popular languages ​​​​in Web development. Before PHP application development, the environment must be configured. PHP needs to be configured on the server to run correctly.

The following is how to test whether the PHP environment is set up properly.

1. Create a phpinfo file

The first step is to create a phpinfo file. This file contains all PHP configuration information, including loaded modules and configurations, PHP version, etc.

Create a new file in the web root directory, such as info.php. Copy and paste the following code into the file:

<?php
phpinfo();
?>

Save and upload the file to the web server ROOT directory.

2. Testing the phpinfo file

Now we need to test our phpinfo file through a web browser. Open a web browser and enter the following URL:

http://yourownwebsite.com/info.php

If you uploaded the phpinfo file to a public server, use the following URL:

http://yourwebhost.com/~yourusername/info.php

If everything is configured correctly, the browser will display the complete PHP information, including version number and all built and loaded modules.

3. Test PHP script

Now you need to test the PHP script. Create a new file, for example test.php. This file should contain some simple PHP code:

<?php
echo "Hello World!";
?>

Save and upload the file to the web server ROOT directory.

4. Test PHP script

Now test our PHP script. Open a web browser and enter the following URL:

http://yourownwebsite.com/test.php

Similarly, if you uploaded the test.php file to a public server, use the following URL:

http://yourwebhost.com/~yourusername/test.php

If everything is configured correctly, browse The browser will display a "Hello World!" text.

Conclusion
