Audits PHP code for memory-efficient, secure, and reliable file I/O patterns and streaming practices.
This skill provides comprehensive auditing of PHP file operations to prevent common pitfalls such as Out-of-Memory (OOM) errors from large file reads, race conditions caused by missing file locks, and disk space exhaustion from uncleaned temporary files. It helps developers transition from basic file functions to professional streaming patterns, SplFileObject usage, and robust error handling using try/finally blocks, ensuring high-performance and secure file processing in any PHP application architecture.
