Debugging and troubleshooting: PHP with MySQL Essential Training (2013)

When the results of your code are not what you expect, you need to start debugging and troubleshooting. The key is to obtain as much information as possible. Debug commands can be used to check the value of variables or even to see what values are returned from a MySQL call. This video reviews the common commands such as echo, print_r and gettype as well as some newer functions like var_dump, get_defined_vars and debug_backtrace. In addition, there is a short overview of third-party debuggers.
