eDM PHP Entity Decoder utility
If you’ve ever had to write HTML emails and ensure decent character rendering across a range of different email clients and browsers then entity encoding your HTML is a must. This can of course be very tedious, so I wrote a PHP based entity encoder for making this job a cut and paste operation.
I used a variation of this extensively in my role at Ogilvy where it seemed to produce reliable and effective output.
