On escaping strings:
https://www.sqlite.org/lang_expr.html
"A string constant is formed by enclosing the string in single quotes ('). A single quote within
the string can be encoded by putting two single quotes in a row - as in Pascal. C-style escapes
using the backslash character are not supported because they are not standard SQL."
Also, there is a nifty PHP function for this. However apparently one must still be cautious of
the null character ('\0' or 0x0), as per https://bugs.php.net/bug.php?id=63419
