Documentation is available at subfields.php
// File_MARC offers the ability to add subfields at any point within
// an existing set of subfields
// First, create some subfields
// Then, create a field including those subfields
// Create some new subfields
// Append a new subfield to the existing set of subfields
$field->appendSubfield ($subfield1);
// Insert a new subfield after the first subfield with code 'z'
// Expected order: a-z-k-g
$sf = $field->getSubfields ('z');
// getSubfields() always returns an array; we just want the first subfield
$field->insertSubfield ($subfield2, $sf[0 ]);
// Insert a new subfield prior to the first subfield with code 'z'
// Expected order: a-t-z-k-g
$sf = $field->getSubfield ('z');
// getSubfield() simply returns the first matching subfield
$field->insertSubfield ($subfield3, $sf, true );
