While searching for existing files if directory
separator is not correct then original files
and directories will be deleted. So use DIRECTORY_SEPARATOR.
Specifically on paste - we don't need all the random style attributes
from content on the clipboard. When you copy from a webpage - the browser
inlines all the styles from the page so that the pasted content will look
like the place it was copied from. But this is never what you want - you
want the content on paste, but with no special styling.

Prevent segfault with ocipo driver on php7.
The OCIFetchinto function is causing segfaults on php7 - probably because the fields array
is not initialised or it is optimised out. This fixes just changes to use the safer function
oci_fetch_array instead.
While this ony seems to affect MySQL, better put the filter/conditions
on every query so the temporary view/table does not need to handle
thousands of potentially unrelated records.
These are our bugs actually - the oci docs are very clear that bound
params should be in-scope when oci_execute is called - and due to pass by value etc,
this was not true for our driver.
There is another bug that needed fixing - OCI barfs if null values are bound - this
can be avoided by setting them to '' which oci treats as null.
And finally - all our lob/clob/blob hacks were also binding to local "out-of-scope" vars.
