I am working to get a straight answer out of the Johannes and Ulf about a related issue and will post back when that becomes available. ------------------------------------------------------------------------ [2012-01-28 00:29:55] frozenfire@php.net Does this issue only arise when using mysqlnd? ------------------------------------------------------------------------ [2012-01-23 20:59:51] johannes@php.net The behavior is correct. We report the same data as we retrieve from the server. The MySQL documentation has more details on this: http://dev.mysql.com/doc/refman/5.5/en/c-api-data-structures.html The key part here is that the data is returned in bytes. On a connection using UTF-8 these are 3 bytes per character. The PHP documentation should be made more clear on this. ------------------------------------------------------------------------ [2012-01-13 18:09:05] danielc at analysisandsolutions dot com Can this please be fixed before PHP 5.4 goes out the door? ------------------------------------------------------------------------ [2011-11-21 18:04:38] danielc at analysisandsolutions dot com That may be the case, but having UTF-8 fields is legit and the answers from libmysql and mysqlnd should be the same. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
