Just a quick one – I needed a script to convert a table to a csv, so this is what I came up with. See the annotations for notes: //html table is in variable $report $report = str_replace(array(“\n”, “\r”), “”, $report); //remove existing line breaks $report = str_replace(‘”‘, ‘\”‘, $report);… Continue reading

After the recent global distributed botnet attack on WordPress installations that took down servers and broke into admin accounts, I thought I’d write a plugin to prevent it happening again. Distributed botnet attacks can come from multiple IP addresses and locations at the same time, so conventional IP-based lockouts are… Continue reading
