$ Data = array ('foo' => 'bar ',
'Baz' => 'boom ',
'Cow' => 'milk ',
'Php' => 'HyperText processor ');

Echo http_build_query ($ data); // foo = bar & baz = boom & cow = milk & php = hypertext + processor
Echo http_build_query ($ data, '', '&'); // foo = bar & baz = boom & cow = milk & php = hypertext + processor
