PHP on OpenShift: How to enable errors and warning

问题:

I have moved my app to OpenShift and now, for convenience of getting it actually work, I'd like to enable in-page errors and warnings. Currently, I see a blank page.

How can I enable errors?

In PHP, it's in php.ini

error_reporting = E_ALL
display_errors = 1

回答1:

On the IRC channel #openshift, I was told that this is not currently not configurable

(05:06:58 PM) pmorie: ozizka-ntb: it looks like it's provided by the cart - i don't believe you can substitute your own

and I need to use both

error_reporting(E_ALL);
ini_set('display_errors', 1);

You might want to set APPLICATION_ENV to development.

$ rhc env set APPLICATION_ENV=development

According to https://developers.openshift.com/en/php-getting-started.html,

In development mode, your application will:

1. Show more detailed errors in browser
2. Display startup errors
3. Enable the Xdebug PECL extension
4. Enable APC stat check
5. Ignore your composer.lock file (if applicable)

If you can't access php.ini then write this on top of your php page:

<?php
error_reporting(22527);
?>

This displays all errors and warnings in the page.
