Checklist for solving problems when coding in PHP[edit]
How to view our linux error log[edit]
I encourage students to open a new tab in their terminal window. The command below will create a running list of errors. To escape from the output, push the key combination control-C.
tail -f /var/log/php/error.log
Problem Solving Steps[edit]
- Repeat the problem, make the error happen again
- TRACE the problem (click here to learn more) - Insert a notification or breakpoint into your program
- Google the problem in general terms. For example:
python how to import a calendar - Re-read your code (sometimes, reading backwards helps you see little errors)
- Use your debugging tools
- Ask a friend
- Google the specific error message your program is raising
- Don't ask your teacher until you have a very specific question.
