Debugging tools

One of the most simple debugging techniques is to print out information from the code using print function to screen. More advanced techniques will include this output to a log file, by doing so the output in the screen will not be polluted by the debug output, but all the debug output will go the a log file. Making debug output going to a log file is a good programming technique. Debugging will slow down execution of this program, so before this program is released to production, most if not all debugging code needs to be removed. Debugging code is mostly for software developers to troubleshoot potential issues.

More advanced debugging can be done with debugging tools. Debugging software allows line by line execution of the code, and it possible to set breakpoints, or points where the execution of the code will be paused, so line by line execution of the code can be performed.

Debugging tools will also show variable values.

In debugging tools it is possible to execute the rest of the code, or until the next breakpoint is set, it is possible step over, or step in. Step over will execute the code which is currently in a debugger, step in functionality will expand that call. Step in is useful to debug function to see if they contain issues.

Errors

It is a good idea to send errors in production environment to error log. Errors may contain sensitive information. Even so errors maybe helpful to development team or to QA team, errors need to be suppressed in production environment for viewing by everyone. Errors are good way to troubleshoot an issue therefore only trusted people can have access to this information. If not a trusted person get an access to this information, this information maybe used against the company and for a personal benefit. What to do in a case when there are more servers than one? Even so it is possible to inspect the log files in a single server, however it is impossible to do so when there is more than one server is available and web traffic is redirected to a different server each time. Log aggregation is needed in this case. All of the logs will be send to a central location. Logs may contain sensitive information. Please consult your company lawyer of how long logs can be stored, because logs can be use...

goto PHP operator

goto operator will skip execution of code and continue execution of a code that follows a label to which goto operator points to. If code has many goto operators, than this code probably needs a revision. It is possible to write code that executes without goto operators.
