I just want to raise my concern about the security issues the current implementation provides. At a glance the update method provides a simple way to execute arbitrary SQL.

Please be aware

Are you referring to a condition where if you let attackers control the array indices or table name, it's merely sanitized for meta characters?

Developer abuse ought to be sufficiently mitigated now. Thanks for saying something :)

No matter how hard you try. If queries are dynamically created, you (or your lib's user) will most certainly miss a spot were an attacker cloud sneak an offensive query.

You fixed the $i, but what about $table? What about $conditions's keys?

See the problem? And we are just talking about a single method ;-)

Valid points, but regrettably they were ones I had already addressed in subsequent changes.

I linked to a single commit.

I probably should have linked to the master branch instead. (Also, I just pushed another update as I wrote this.)
