This class just sucks:
1- WTF "const" in php4?? needed to make it 'define' and correct it in every file that uses it. If i could use const i would use the native php5 PDO !!
2- execute() : magic quotes or not?? oops, had to correct it myself (again) because it\\\\\\\\\\\'s not cool to read :(
3- in this version, you HAVE to make semicolons the arraykeys whereas in the native version of pdo, you have the choice to put it or not (and then not much key renaming)
4- CONFLICTS in query execution (for example : using variables named ":login" and ":loginErp" will just crash the query ^^) yahoo!
i tested the mysql version only, don't wanna see what's going on for the other db engines, that's enough for me ^^
