PHP 7 provides major performance improvements and new features like scalar type hinting. Benchmarks show PHP 7 code running around 50-90% faster than PHP 5.6 for the same applications, with more significant speedups when opcodes are cached. PHP 7 aims to modernize PHP and bring it more in line with languages like Java in aspects like interfaces while maintaining backwards compatibility.
