What Is the Example of PHP Scripting Language?

PHP is a popular scripting language used for web development. It is widely known for its simplicity, flexibility, and ease of use. In this article, we will explore some examples of PHP scripts that demonstrate its power and versatility.

Basic Hello World Script

Let’s start with a simple example – the classic “Hello World” script. This script will display the message “Hello, World!” on a web page when executed.

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

To run this script, save it with a .php extension (e.g., helloworld.php) and open it in a web browser. You will see the output “Hello, World!”

displayed on the page. Congratulations! You have successfully executed your first PHP script.

Using Variables

PHP allows us to store and manipulate data using variables. Let’s look at an example that demonstrates how to use variables in PHP:

  
    <?php
      $name = "John Doe";
      $age = 25;
      
      echo "Name: " . $name . 

"
"; echo "Age: " . $age; ?>

In this example, we declare two variables: $name and $age. We assign the value “John Doe” to $name and 25 to $age. The echo statements then display the values of these variables along with some additional text.

Conditional Statements

PHP also supports conditional statements, which allow us to execute certain code blocks based on specified conditions. Let’s take a look at an example:

  
    <?php
      $num = 10;
      
      if ($num > 0) {
        echo "Positive";
      } elseif ($num == 0) {
        echo "Zero";
      } else {
        echo "Negative";
      }
    ?>
  

In this script, we assign the value 10 to the variable $num. The if statement checks whether $num is greater than zero, equal to zero, or less than zero and displays the corresponding message accordingly.

Loops

PHP provides various loop structures that allow us to repeat a certain block of code multiple times. Let’s look at an example using the while loop:

  
    <?php
      $i = 1;
      
      while ($i <= 5) {
        echo "
  • " . $i . "
  • "; $i++; } ?>

    In this example, we initialize the variable $i with the value 1. The while loop then iterates as long as $i is less than or equal to 5. Inside the loop, we echo out the value of $i within an HTML list item (

  • ) and increment $i by one in each iteration.

    Conclusion

    These examples showcase just a few of the many possibilities with PHP scripting language. From basic output statements to complex conditional logic and loops, PHP offers a wide range of features for web development. By mastering the fundamentals and exploring its extensive documentation, you can harness the full potential of PHP and build dynamic and interactive web applications.
