Enclosing values in single quotes

От

I am trying to write a function which takes in an associative array (from a
user submitted form for example), converts the keys to a column array and
values to a value array. These arrays together with the name of the database
table are fed into another function, which generates the query string (insert
into $table ($colmn) values ($value)).

As a short cut,  I am enclosing all the values (numeric as well as strings)
in single quotes when generating the arrays.  In my trials so far,
everything is fine. What will be the issues in enclosing numeric values in
single quotes?

(I am learning this as a hobby and I do not have any formal training in
programming).

Any advice please.

Siva

Absolutly none. In fact, it will work better than if you attempt to leave
them off, since without quote, they'll all be interpreted as int4. With
quotes, they'll all be interpreted by the appropriate input function for
each type.

Don't forget to escape the ' and \ characters.
