Frage
I was going through a manual and found a statement saying "if array element used with '-' as the word separator, the array's element can be accessed by magic quotes".. but didn't provided with any explanations on it. could some one explain the reason behind this?
Lösung
It's seemingly this one (since OP won't tell us):
http://www.dagbladet.no/development/phpcodingstandard/#arrayelement
Here "magic quotes" is simply the wrong designation. They mean double quoted string interpolation, specifically:
print "$myarr[foo_bar] world";
versus
print "$myarr[foo-bar] world"; // invalid
And indeed only the first one is correct syntax. Else use curly braces and key quotes:
print "{$myarr['foo-bar']} world";
