Debugging PHP Code

[blueprint]

For those that may not be aware, the following is really useful when debugging PHP code:

$GLOBALS['log']->debug('Here is my variable:', [$variable]);

You just need to ensure that in your `data\config.php`, the relevant logging `level` is enabled for your output:

'logger' => [
        'path' => 'data/logs/espo.log',
        'level' => 'DEBUG',
        'rotation' => true,
        'maxFileNumber' => 30
    ],

Then you just need to check your log file (in the above path) for the messages. This has helped us massively!

Available options are:

DEBUG
INFO
NOTICE
WARNING
ERROR
CRITICAL

Thanks blueprint I am currently struggling with a PHP stupid bug. Sorry if this is quite obvious but in which script do I write

 
 $GLOBALS['log']->debug('Here is my variable:', [$variable]);

?

That all depends which script is causing you the issue.

For example, I've recently been debugging some hooks so I've added the above code a number of times in the `beforeSave` function.

I've also previously littered the majority of the ORM php files with debug statements just so I could figure out the program flow.

Thanks so much, it's like using "console.log" to debug javascript, excellent !

Thanks blueprint, great tip!

I add a note: I found the default logger[] array setting in config-internal.php. This is important, because this will override the logger[] settings defined in config.php.

Just had to edit the default WARNING level to DEBUG in config-internal.php, and logging works well.
