Help me understand this code :
Array
(
[font-family] => font-family: 'Abel', sans-serif;
[font-name] => Abel
[css-name] => Abel
)
from : http://phat-reaction.com/googlefonts.php .
Why there are no quotes around keys and values ? Is this valid php code ?
It is a dump of some array data in a format designed for a human to read, not code. See print_r.
No.
