Question

I’m wondering why when i put an sql ADODB query in side a function it produces the following error:

Fatal error: Call to a member function Execute() on a non-object in -path to script-

My function is something like:

$dsn = 'mysql://user:pass@localhost/db'; 
$db = ADONewConnection($dsn);

function getem($q){
$r=$db->Execute($q);
return $r->RecordCount();
}

echo getem("select * from table");

Any ideas how to fix that?

Answer 1

Variable Scope Issue

You need to import $db instance into your function using global keyword:

function getem($q){
  global $db;

  $r=$db->Execute($q);
  return $r->RecordCount();
}

That should do the trick.
