The 'do' loop in this example will cycle indefinitely until all curl downloads complete, needlessly using CPU cycles. A much better way is to block while dowloads are in progress. Refer to the example code on the curl_multi_exec() page instead, which does this!

Sometime with arrays and loops (i.e. for or do while or foreach) curl_multi_init loses some hits, to work around this problem it is necessary to divide the loop into two parts: the start with key number zero and than, all the rest. In this way the curl_multi_init doesn't lose any hits. I did a lot of test and it seems to work well enough.
