PHP codestyle question re. isset( $array['key'][0] ) versus array_key_exists( 0, $array['key'] )
On a recent patch [1], we had a discussion what is - or may be - better * isset( $array['key'][0] ) * array_key_exists( 0, $array['key'] ) This is still unclear after consultation of these pages * http://php.net/isset <http://php.net/isset,> * http://php.net/array_key_exists and * https://www.mediawiki.org/wiki/Manual:Coding_conventions/PHP#Pitfalls . ... I would prefer/array_key_exists/ . Perhaps someone can explain why which one of the methods should be preferred ? The https://www.mediawiki.org/wiki/Manual:Coding_conventions/PHP#Pitfalls section should be improved with the explanation.
