Troubleshoot

To troubleshoot is to diagnostic and correct a problem in a piece of software. It involves gathering information, isolating the root cause, applying solutions, and verifying functionality, often starting with simple checks like rebooting to resolve errors, slow performance, or connectivity problems.

Troubleshoot applies to every aspect of the lifecycle of PHP: installation, running the code, performing under constraints, etc.
