Working with an array with periods in key values
I’m getting data from an array. For some reason the array has key values like [3.3] which I’m having trouble retrieving data from. I have this array [3.3] => First Name [3.6] => Last Name[2] => email@example.com. When I try to call $array[3.3] it returns null, but when I call $array[2] I am given the e-mail. Any ideas? Answer Use
