The first one is the proper syntax (the associative index name in quotes.)

 

The second one works because php makes an assumption that if it does not find a constant with the name used that tries to find an associative index with that name. This however takes 10-20 times longer to execute because php first checks the table of all the defined constants (user and php) for a match, goes through the error response code when it does not find a matching defined constant, assumes you meant a quoted associative index, finds the associative index and finally references the associative array variable. Don't use the second form unless you want your code to execute as slow as possible.
