“You can compress/decompress long strings before storing them in a database”

Bravo! So when it comes to query these records and use the gzip-compressed field in a WHERE clause…. you would go about doing that how?

This sort of inanity is the reason PHP regrettably cops the reputation of being a second rate, amateur-hour language.

The last one could also be done like so:

array_filter(explode(“,”,$string));

I know preg_split is more expensive than explode, not sure if combining it with array_filter is going to change that though.

be careful though, as written, it will also remove anything that evaluates to false. You can write your own callback to just remove empty strings though.

@#1
How do you expect to perform a search on your data through MySQL if you have it all compressed in gZip format?

Number 2 is slightly misleading. It checks that the domain, IP, etc., resolve correctly (the proper records exist). It does not, however, confirm that an email address is in use.

Furthermore, you cannot use “user@*” in the string passed to checkdnsrr().

$class_name = function_to_get_class_name();
$my_class = new $class_name();

Zend_Framework does this a lot.

Great Post. It’s amazing how versatile PHP is. The amount of libraries is also a great resource.
