There is a bug in PHP 4.3.0 regarding the use of arrays
in strings. The following gave a parse error before
PHP 4.3.0:
print "Do not do this: $arr['key']";
Now it gives an E_NOTICE error due to changes to the string
scanner. In PHP 4.3.1 it will no longer give a bogus E_NOTICE
and instead it will work (no parse error either). Surrounding
the array with {braces} in the string works regardless, so:
print "You can do this: {$arr['key']}";
Regarding this question, don't write it like that but instead
do the following (no quotes needed):
echo $new['company'];
For those wondering about this bug, see:
http://bugs.php.net/bug.php?id=21820
The string documentation has been updated to demonstrate
the array in string phenomena (except the bug hasn't been
mentioned as I'm waiting for it to be committed first).
http://www.php.net/types.string
Sunfire, you aren't seeing this E_NOTICE error because your
error level is turned down (by default). Put this on top
of your script to see them all:
error_reporting(E_ALL);
