Operating system: Win XP Pro, Win server 2003
PHP version: 5.2.10
PHP Bug Type: MySQL related
Bug description: collation discreapency between mysql.exe client and mysql
extensions.
Description:
------------
php_mysql.dll (or php_mysqli.dll) extension do not use the same
configuration as MySQL.exe, so if you run the same query from both sides
you will not get the same results.
I know I can use the following :
@@mysql_query("SET NAMES 'utf8'",$my);
on a fresh connection, but if the MySQL configuration changes I must have
to change the php code as well.
Reproduce code:
---------------
PHP code :
$rec=@@mysql_query("show Variables LIKE 'c___a%_%'",$my);
while($row=mysql_fetch_assoc($rec)){
foreach($row as $n=>$v){
echo $v."\n";
}
}
MySQL code ;
show Variables LIKE 'c___a%_%';
Expected result:
----------------
Mysql.exe results :
Variable_name Value
character_set_client utf8
character_set_connection utf8
character_set_database utf8
character_set_filesystem binary
character_set_results utf8
character_set_server utf8
character_set_system utf8
character_sets_dir ...\share\charsets\
collation_connection utf8_general_ci
collation_database utf8_general_ci
collation_server utf8_general_ci
Actual result:
--------------
php_mysql.dll results :
Variable_name Value
character_set_client latin1
character_set_connection latin1
character_set_database utf8
character_set_filesystem binary
character_set_results latin1
character_set_server utf8
character_set_system utf8
character_sets_dir ...\share\charsets\
collation_connection latin1_swedish_ci
collation_database utf8_general_ci
collation_server utf8_general_ci
