Answer 1

Just for the next newbie, another example of how this error

" PHP Fatal error: Function name must be a string in ..."

is triggered / and solved is as below;

Say you have an associative array;

$someArray = array ( 
                 "Index1" => "Value1",
                 "Index2" => "Value2",
                 "Index3" => "Value3"
              );

echo $someArray('Index1'); // triggers a fatal  error as above

Solution:

echo $someArray['Index1']; // <- square brackets - all good now

Answer 2

$mysql_query($query); => mysql_query($query);. Note the missing dollar. If you try to use function call syntax on a variable, it looks for a function with the name given by the value of the variable. In this case, you don't have a mysql_query variable, so it comes back with nothing, which isn't a string, and thus gives you the error.

Answer 3

You have a stray $ on mysql_query. Remove it:

mysql_query($query);
