I get some very strange results when I use an β_β for example $first_name$β in a variable name. Specifically if I use this in a table and try and insert 3 rows of data only the first row is inserted. However if I take out the β_β and use $firstname$ it seems to work ok. I suspect it may be a preg_replace issue but canβt be sure
Any idea if this is a known issue ?
