Question

I have code with the following form:

<?php function doSomething{   //Do stuff with MySQL   $con->tralalala(); } $con = connectToDatabase;//This would actually be a line or two. doSomething(); ?> 

This (type of) code doesn’t work, because doSomething() doesn’t have a connection to the database. Can anyone explain why not? I create the $con connection before I call doSomething(). So why does the function act as if there’s no connection?

Is there any way to fix this, short of passing the connection into the function like doSomething($con)?

Answer 1

you probably need to tell it to look in the global scope:

      function doSomething()      {          global $con;          $con->tralalala();      }
