Hi, i'm going to join a mid-size company with a few PHP-driven projects written in procedural PHP, million years old. At the moment, they don't have a wiki or any documentation about their projects. For me, the first challenge in probation period is to understand how their code works. * Considering that there is no wiki or docs, How can I see the Big Picture?* i'm sure this is a common problem for programmers everywhere. What approach do you use in a similar situation? Is there a systematic approach for this? Is there reverse-engineering technique to understand the design of code? Please share your experience and thoughts. -Thanks in advance, Behzad
