How to check massive availability of domain names using PHP?
<p>How do I check the domain availability of every domain in a long list? For example, I would like to choose a base word, e.g. "overflow" and check for domain availability of all 3-letter combinations after the word, e.g. "overflowabc"</p>

<p>Is there a script written for this? Is it legal to do a massive search like this?</p>
