Is there a way to identify the type of field that is coming in a post?
If it's Text or Array?
Example:
I have listbox (select multiple) and text fields in html, and in it the user can select values or not, I have a function where I check the values of the fields before proceeding, but when I have this type of field in between I get the problem , I needed to treat it differently when it comes in the post.
There is the gettype() function that returns a string that identifies the data type that is the variable passed to the parameter, even if it is an array. You can use this to handle your code.
For example, a gettype([1,2]); would return 'array' , gettype(1); would return 'integer' , gettype('teste'); would return 'string' , and so on. It is also possible to do this for values coming via post, such as gettype($_POST['campo']); .
