Question 1

How do I install YaLinqo using Composer?

Accepted Answer

Add 'athari/yalinqo': '^3.0' to your composer.json require section and run composer update. Then, include vendor/autoload.php in your script to use the Enumerable class or global 'from' function, as shown in the usage example.

Question 2

Is YaLinqo better than Laravel's collections for data processing?

Accepted Answer

YaLinqo excels in fidelity to .NET LINQ and lazy evaluation performance, while Laravel collections are more integrated with the Laravel ecosystem and offer framework-specific features. Choose based on whether you need pure LINQ semantics or Laravel compatibility, as noted in the alternatives section.

Question 3

Does YaLinqo's lazy evaluation actually improve performance with large arrays?

Accepted Answer

Yes, lazy evaluation processes data on-demand, reducing memory usage and avoiding unnecessary computations. Benchmarks in the YaLinqoPerf repository show significant speed advantages over eager alternatives for large datasets, supporting the performance claims.

Question 4

How can I use arrow functions with YaLinqo callbacks?

Accepted Answer

YaLinqo fully supports PHP arrow functions (e.g., fn($v) => $v) for callbacks, making code concise and modern. The library is designed to work with PHP 7.4+ arrow functions and first-class callables from PHP 8.1, as demonstrated in the example code.

Question 5

What are the security concerns with string lambdas in older YaLinqo versions?

Accepted Answer

In versions 2.x and earlier, string lambdas use eval() to parse code, which can execute arbitrary PHP if user input is included. The README strongly warns against using dynamic strings and recommends avoiding string lambdas for security, with detailed cautions in the legacy features section.

Question 6

Is YaLinqo compatible with PHP 8.2 or higher?

Accepted Answer

Yes, YaLinqo 3.x is compatible with PHP 7.0 and above, including PHP 8.2+. However, for optimal use with PHP 8+'s features like first-class callables, ensure you're using the latest version within the 3.x series, as compatibility is maintained per the version table.
