Why PHP Powers Most of the Web

📖 Scenario: Imagine you are a web developer learning why PHP is so popular for building websites. You want to create a simple PHP script that shows some reasons why PHP powers most of the web.

🎯 Goal: You will build a PHP script that stores reasons why PHP is popular in an array, filters the reasons based on a minimum length, and then displays the filtered reasons on the web page.

📋 What You'll Learn

Create an array called $reasons with 5 exact reasons as strings

Create a variable called $minLength set to 15

Use a foreach loop to create a new array $filteredReasons containing only reasons with length greater than or equal to $minLength

Print each filtered reason inside an HTML <li> element within an unordered list

💡 Why This Matters

🌍 Real World

PHP is widely used to build websites and web applications. Filtering and displaying data dynamically is a common task in web development.

💼 Career

Understanding PHP basics like arrays, loops, and string functions is essential for backend web development jobs.

1

Create the reasons array

Create an array called $reasons with these exact strings: 'Easy to learn', 'Wide hosting support', 'Large community', 'Fast development', 'Open source'.

PHP

<?php

// Create the array $reasons with the 5 exact strings
// Your code here

Need a hint?

Use the PHP array syntax with square brackets and separate strings with commas.

2

Set the minimum length variable

Create a variable called $minLength and set it to 15.

PHP

<?php
$reasons = ['Easy to learn', 'Wide hosting support', 'Large community', 'Fast development', 'Open source'];

// Create the variable $minLength and set it to 15
// Your code here

Need a hint?

Use the assignment operator = to set the value.

3

Filter reasons by length

Use a foreach loop with variable $reason to iterate over $reasons. Inside the loop, add $reason to a new array called $filteredReasons only if its length is greater than or equal to $minLength. Use the strlen() function to get the length of the string.

PHP

<?php
$reasons = ['Easy to learn', 'Wide hosting support', 'Large community', 'Fast development', 'Open source'];
$minLength = 15;

// Use a foreach loop to filter reasons by length
// Your code here

Need a hint?

Initialize $filteredReasons as an empty array before the loop.

4

Display the filtered reasons

Use a foreach loop with variable $reason to iterate over $filteredReasons. Inside the loop, print each $reason inside an HTML <li> element. Wrap the list items inside an unordered list <ul>.

PHP

= $minLength) {
        $filteredReasons[] = $reason;
    }
}

// Print the filtered reasons inside  and  tags
// Your code here

Need a hint?

Use echo to print HTML tags and list items.
