Open PHP MyProfiler is a MySQL DBA and DevOps professional's tool to run query profiling on a php-mysql application, without changing the architecture too much. The profiler is open and downloadable. Anyone who needs to do the analysis could make use of the same by downloading the profiler and implementing it with their code. The profiler would create logs depending on the hostname and date.

Features:

Non-invasive profiling: Integrates seamlessly into PHP-MySQL applications without requiring major code changes.

Query performance tracking: Captures detailed information about SQL queries executed within your application.

Log-based analysis: Stores profile data in logs for offline analysis and review.

MySQLi compatibility: Supports both MySQL and MySQLi connections.

Customization: Allows for configuration of profiling settings to suit specific needs.

Performance optimization: Identify and address performance bottlenecks in your PHP-MySQL applications.

Query analysis: Analyze query execution patterns, identify slow queries, and optimize database schema and indexes.

Debugging: Diagnose and troubleshoot database-related issues.

Application monitoring: Track the performance of your application over time and identify trends.

Technical Skillset:

PHP development: Understanding of PHP syntax, object-oriented programming, and database interactions.

MySQL knowledge: Familiarity with MySQL database structure, query optimization techniques, and performance tuning.

Log analysis: Ability to interpret and analyze log data to identify performance issues.

Debugging skills: Experience in debugging PHP applications and resolving database-related errors.

Basic system administration: Understanding of file system operations and configuration.

While PHP MyProfiler provides valuable insights into query performance, it's essential to consider potential performance overhead introduced by profiling. For production environments, it's recommended to use profiling selectively when absolutely needed to check what is going wrong and where.
