[#3940] Adding php example for an array of emails

[weaverryan]

This follows #3940. It just adds the example also to PHP. But I can't see how this would work with XML.

I guess this is actually not possible with XML since you can't set an attribute multiple times.

[wouterj]

This should work:

<monolog:config>
    <monolog:handler name="swift" ...>
        <monolog:to-email>[email protected]</monolog:to-email>
        <monolog:to-email>[email protected]</monolog:to-email>
    </monolog:handler>
</monolog:config>

(iirc, the XML parser doesn't parse elements or attributes differently, you can replace all attributes by elements)

@wouterj The issue is that the MonologBundle XML schema doesn't allow to-email elements: https://github.com/symfony/MonologBundle/blob/master/Resources/config/schema/monolog-1.0.xsd#L18-28

[wouterj]

@xabbuh then someone should fix that. If we don't put the scheme in schemeLocation, it'll not be validated and work perfectly

[xabbuh]

@wouterj I'm preparing a pull request on the MonologBundle.

[xabbuh]

see symfony/monolog-bundle#91

[weaverryan]

Nice work @xabbuh! I think we should merge this and then update the docs later after that code PR is merged. Make sense?

[xabbuh]

@weaverryan I'm fine with that. We can update the XML example once the pull request on the MonologBundle is merged.

Thanks for the quick responses guys!
