💼 Career

Many web developer jobs require knowledge of PHP request flow to build and debug web applications.

1

Start the PHP request with a message

Write a PHP script that prints the message "Request started" at the very beginning using echo.

PHP

<?php

// Print "Request started" message
// Your code here

Need a hint?

Use echo to print text in PHP. Remember to include a newline character \n for clarity.

2

Add a configuration variable for the request name

Add a variable called $requestName and set it to the string "HomePage".

PHP

<?php

echo "Request started\n";

// Create a variable $requestName with value "HomePage"
// Your code here

Need a hint?

Use $requestName = "HomePage"; to create the variable.

3

Use the request name in the main logic

Write a line that prints "Processing request: HomePage" using the variable $requestName and echo.

PHP

<?php

echo "Request started\n";

$requestName = "HomePage";

// Print "Processing request: HomePage" using $requestName
// Your code here

Need a hint?

Use double quotes and include the variable inside the string to print it.

4

Print the end message to finish the request

Add a line that prints "Request ended" using echo to show the PHP request finished.

PHP

<?php

echo "Request started\n";

$requestName = "HomePage";

echo "Processing request: $requestName\n";

// Print "Request ended" message
// Your code here

Need a hint?

Use echo "Request ended\n"; to print the end message.
