How can printing functionality be implemented in PHP?

In PHP, you can use the echo or print statements to achieve printing functionality. Below is a simple example:

<?php
echo "Hello, World!"; // 使用echo语句打印字符串
print "Hello, World!"; // 使用print语句打印字符串
?>

The code above will output “Hello, World!” to the page. You can place the content you want to print inside an echo or print statement to achieve the printing function.
