What's happening is that your array of area_codes that you read from the
file has newlines after each value.
array
0 => string '800
' (length=5)
1 => string '801
' (length=5)
2 => string '802
' (length=5)
3 => string '803
'
...and so on. When it's searching for "801" as a string, it doesn't
match "801\n". However, when you search for 801 as an int, it casts the
array value to an int as well, which drops the newline. Then it matches.
You could try just changing the one line to
$area_codes[] = trim(fgets($file_handle));
which works as you expect.
