sqldatatypes - PHP - What is the "data type" of $link in this case? $link = mysql_connect() -


Disclaimer

I know that mysql_ [command] functions get weaker It is for a school project and before they get disconnected, I did not mark the "up-to-date-ness" of the functions used, only because of the complex-nature of the program I have written so that the PDO or There was no incentive to change Myscle. For example, despite not being defined in the same way as vb.net, I must include a variable-listing of all variables (including data type ...).

My big question is!

What is the data type of variable $ link in the code listed below? Where a data type is a string, integer, bullion value, etc. For example ... 

  $ link = mysql_connect ('localhost', 'mysql_user', 'mysql_password'); If (! $ Link) {die ('could not connect:' mysql_error ()); } 
 
 If it connects successfully it will be a resource identifier, otherwise Boolean :  
 
 FALSE on a MySQL link identifier or failure on success.

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number".

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
