    style parameter markers to something more appropriate, if the driver
    supports one style but not the other.

+    As of PHP 5.3.0, the parser used for emulated prepared statements and for
+    rewriting named or question mark style parameters supports the non standard
+    backslash escapes for single- and double quotes. That means that terminating
+    quotes immediately preceeded by a backslash are not recognized as such, which
+    may result in wrong detection of parameters causing the prepared statement to
+    fail when it is executed. A work-around is to not use emulated prepares for
+    such SQL queries, and to avoid rewriting of parameters by using a parameter style
+    which is natively supported by the driver.
