To retrieve an identifier from a table in order to be able to work it separately, the problem I have is that when I get it, the sql query gives it to me in the form of a table that I was not able to to convert to a chain.
Here is the code:
$ idClient = DB :: select ("SELECT id among clients WHERE nit = $ nit"); echo $ idClient;
the array will contain only one element, but it has not been able to convert it to a string, whereas it is only one element.
it comes to me as an error:
I want to get this "id" of the query in string form, but I could not.
