Apache2 php error.log pretty format

You're looking through the apache error log and you see this:

[Fri Oct 15 17:58:43.458518 2021] [php7:error] [pid 41144] [client ::1:46744] PHP Fatal error:  Uncaught Error: Call to a member function getStockStatus() on bool in /var/www/example.com.localhost/vendor/magento/module-catalog-inventory/Model/Quote/Item/QuantityValidator.php:157\nStack trace:\n#0 /var/www/example.com.localhost/vendor/magento/module-catalog-inventory/Observer/QuantityValidatorObserver.php(34): Magento\\CatalogInventory\\Model\\Quote\\Item\\QuantityValidator->validate(Object(Magento\\Framework\\Event\\Observer))\n#1 /var/www/example.com.localhost/vendor/magento/framework/Event/Invoker/InvokerDefault.php(88): Magento\\CatalogInventory\\Observer\\QuantityValidatorObserver->execute(Object(Magento\\Framework\\Event\\Observer))\n#2 /var/www/example.com.localhost/vendor/magento/framework/Event/Invoker/InvokerDefault.php(74): Magento\\Framework\\Event\\Invoker\\InvokerDefault->_callObserverMethod(Object(Magento\\CatalogInventory\\Observer\\QuantityValidatorObserver), Object(Magento\\Framework\\Event\\Observer))\n#3 /var/www/example.com.localhost/vendor/magento/module-staging/Model/Event/Manager.php(97): Magento\\Framework\\Event\\Invoke in /var/www/example.com.localhost/vendor/magento/module-catalog-inventory/Model/Quote/Item/QuantityValidator.php on line 157, referer: http://example.com.localhost/run-away-basics-rugzak-15039001.html

Which isn't really handy for debugging

Now if you use the below command in bash, to pretty format the apache 2 error log for php fatal errors, you get a nicer output(in my opinion)

tail -f /var/log/apache2/error.log | grep 'PHP Fatal error' | grep '/var/www/example.com' | sed -u -e 's/\\n/\n/g' | sed -e 's/\.php(\([0-9]*\)):\s/.php:\1 /g'

Now if you're using phpstorm and you install the plugin Awesome console they'll even become clickable in run output and console output, so you can simply click, go to the correct file and line and debug from there.

Say we add a composer script for easy composer run configuration in php storm, even then the output there is clickable to open the file at line.

    "scripts": {
        "dev-server-log": [
            "tail -f /var/log/apache2/error.log |  grep '/var/www/example.com' | sed -u -e 's/\\\\n/\\n/g' | sed -e 's/\\.php(\\([0-9]*\\)):\\s/.php:\\1 /g' "
        ]
    },
Enter fullscreen mode Exit fullscreen mode

The awesome console plugin isn't perfect, and doesn't always make all links clickable, but every time you don't need to select a line and open the file that way, is time saved.

Happy coding!
