SolrQuery::getSortFields() is a method in the PHP Solr extension that retrieves the sort fields specified for a Solr query.

The SolrQuery::getSortFields() method is used to get the sort fields that have been set for a Solr query. It returns an associative array where the keys are the field names and the values are the sort order.

Here is an example that demonstrates the usage of SolrQuery::getSortFields():

php
// create a new Solr query
$query = new SolrQuery();

// set a sort field to sort the results
$query->addSortField('field1', SolrQuery::ORDER_DESC);

// get the sort fields that have been set
$sortFields = $query->getSortFields();

// iterate over the sort fields and print them out
foreach ($sortFields as $field => $order) {
echo "Sort field: $field, Sort order: $order\n";
}


In this example, we create a new SolrQuery object and add a sort field using the addSortField() method with the field name 'field1' and the sort order SolrQuery::ORDER_DESC (descending order). We then call the getSortFields() method to retrieve the sort fields that have been set, and finally, we iterate over the sort fields and print them out.

The output of this example would be:
Sort field: field1, Sort order: desc

This means that the query is sorted by the field 'field1' in descending order.
