PHP Array Key encoding?

Question

I use a encoded string as a key in array, and also uses the same string as a value in the array, like below code indicates:

$string = \'something in some enc         


        

Answer 1

I don't know if you can encode correctly string to use them as keys in an array, but even if it is possible to use such variables names :

• $élement = 'foo';
• $garçon = 'bar';

(note the ç and the é)

It is not recommended. You should not rely on this.

You would probably map with current english name or use indexes.

For utf8 encoding, take a look at the php manual.
