I believe the correct syntax would be:
 
 $layer->setFilter("([CAMPO]='$var')");

You need:
 - Square brackets around field names
 - Parenthesis around the expression to indicate that it's a logical
   expression.

Note that since you're evaluating a single attribute value, then using a
constant expression instead of a logical expression would be more
efficient:

  $layer->set("filteritem", "CAMPO");
  $layer->setFilter( "\"$var\"" );
