1. The Missing PHP 7 DSA Handbook (GitHub Community Edition)

Best for: Practical, runnable code examples.

• Content: Covers Arrays (SplFixedArray), Linked Lists, Stacks, Queues, Binary Trees, Bubble/Quick/Merge Sort, Binary Search, and BFS/DFS for Graphs.
• Why it’s great: Written specifically for PHP 7.4+ (includes typed properties and arrow functions).
• Download: Available as a free PDF release from the php-dsa GitHub repository. Search for "php-dsa-handbook.pdf github release" or check the "Wiki" section of popular PHP algorithm repos.

1. Arrays (The King of PHP)

PHP arrays are actually ordered hash maps. A good PDF will teach you when to use SplFixedArray to reduce memory overhead by 30-40% compared to normal arrays when dealing with millions of entries.

Example from a top-tier PDF:

// Using SplFixedArray for 100k integers
$array = new SplFixedArray(100000);
for ($i = 0; $i < 100000; $i++) 
    $array[$i] = $i;
// memory usage: ~4 MB vs 12 MB for regular array

The Reality of "Free PDF Download"

Many websites claiming "free PDF download" for popular DS&A books are either: "Recursive tree traversal using generators").

1. Pirated copies (illegal, often malware-ridden, and disrespectful to authors).
2. Outdated (PHP 5.6 or older).
3. Incomplete (scraped blog posts stitched together).

Instead of chasing risky PDFs, here are the legitimate best works you can access for free (legally) or at minimal cost.

3. The "Best Work" Method: LeetCode in PHP 7

Most developers use LeetCode with Python/Java. But you can solve problems in PHP 7:

• Filter LeetCode problems by "Easy" or "Medium."
• Implement solutions using PHP 7’s type system.
• Compare your solution to the C/Java reference answers to understand performance.

Pro tip: Create a cheat sheet of PHP 7 DSA patterns (e.g., "Two-pointer technique with array", "Recursive tree traversal using generators").

2. Linked Lists

Why use linked lists in PHP? For implementing undo/redo functionality or a message queue. A great PDF will show you how to leverage PHP 7’s SplDoublyLinkedList and also implement a custom singly linked list to understand pointers.
