Re: Dynamically named variables and arrays.

I'm not quite sure what you're trying to do, but this is performing a replace on a string, not a variable" $requiredPostFieldName = str_replace( "sales_data", "", "sales_data[area][2]" ); I believe this will set $requiredPostFieldName to "[area][2]" Also, you might want to try breaking the second line into multiple interim variables to get it working, then collapse it back to one line.
