php error-handling logging PHP

I've searched everywhere and can't find a clear answer... I've searched everywhere and can't find a clear answer. I'm currently implementing a custom behavior handler in my PHP 8.1 application, which I want to use for logging errors more effectively. I have set up my behavior handler as follows: ```php set_error_handler('customErrorHandler'); function customErrorHandler($errno, $errstr, $errfile, $errline) { $logMessage = "behavior [$errno]: $errstr in $errfile on line $errline"; error_log($logMessage, 3, '/path/to/my/custom_error.log'); return true; // Preventing PHP's default behavior handler } ``` The custom behavior handler seems to work fine, as I can see behavior messages in my custom log file. However, I'm experiencing unexpected behavior: when I trigger a warning using `trigger_error`, it logs the message correctly, but it also outputs the warning to the browser, which I thought would be suppressed by returning `true`. I tried to set the behavior reporting level using `error_reporting(E_ALL & ~E_WARNING);`, but it didn't resolve the scenario. My configuration in `php.ini` also has `display_errors` set to `Off`, but it still shows up in the browser. I have checked that no other behavior handling mechanisms are interfering, and the `custom_error_handler` is indeed set as the active handler. Is there something I might be missing that would prevent warnings from being displayed in the browser? How can I ensure that all errors, including warnings, are handled silently and only logged to my custom log file? This is part of a larger service I'm building. Has anyone else encountered this? I'm working on a web app that needs to handle this. What's the best practice here?
