PHP Coding Interview Practice
PHP powers a significant portion of the web — WordPress, Laravel, and Facebook's backend started in PHP. Engineers at web agencies, e-commerce companies, and content platforms often interview in PHP. Modern PHP (8+) has shed its reputation with strong typing, named arguments, fibers, and a competitive performance profile.
Why PHP for Interviews?
Modern PHP 8 offers union types, named arguments, match expressions, and null safe operators. The SPL library provides SplStack, SplQueue, SplMinHeap, and SplMaxHeap for common data structures. PHP's array functions (array_map, array_filter, array_reduce, usort) are powerful for algorithm problems.

PHP Interview Tip
Use arrays for both lists and hash maps in PHP (they're the same type). array_flip for inverting key/value pairs, array_unique for deduplication, and usort for custom sorting are interview essentials. Use SplStack and SplQueue from the SPL extension for explicit stack/queue behavior.
