Say you have a string $someword and you need to use it within a query like:
"SELECT whatever where MATCH(whatever) AGAINST('+$someword +someotherword' IN BOOLEAN MODE)"
You need to properly escape certain characters in $someword so that you don't get syntax errors in the boolean search expression. I know I'm being sloppy at defining what needs to be done. Actually I'm pretty sure there are different kinds of escaping you would need for different use cases, but it's certainly possible to define them unambiguously.
Expected: there should be methods in the MySQLi class for this.
Observed: you have to write your own code, and you'll almost certainly get it wrong; or you'll have to find some 3rd party libraries, which is pathetic.
