Debugging, Tracing, and Profiling

Zend Z-Ray


The Rougue Wave Software company offers a commercial PHP server called Zend Server. One of Zend Server's outstanding features is its Z-Ray extension. Seemingly analogous to Xdebug’s tracing and profiling functionality, Z-Ray offers comprehensive information capturing and  an improved user experience. Captured information ranges from execution times, errors and warnings, database queries, and function calls to request information. These are provided in a form that resembles a built-in browser’s developer tools, making it easy for the developer to retrieve a vital piece of profiling information within seconds.

Note

The Z-Ray extension itself is free, and can be used independently off the commercially available Zend Server. We can install it just like any other PHP extension. Although, at the time of writing, the stand-alone Z-Ray extension is available only for the PHP 5.5 and 5.6 versions, which are now considered outdated.
