public arrayMongoCollection::deleteIndex
string|arraykeys
+
+ This method is identical to:
+
+
+toIndexString($keys);
+
+ return $this->db->command(array("deleteIndexes" => $this->getName(),
+ "index" => $index);
+}
+
+?>
+]]>
+
+
+ Each index, when created, is given a unique name. This is generally user-set
+ (with MongoCollection::ensureIndex's "name" option) or
+ generated by the driver from a combination of key names and directions. This
+ name is then used by MongoCollection::deleteIndex to
+ remove the function.
+
+
+ Unfortunately, the MongoCollection::ensureIndex
+ generates slightly different names than the shell and, due to backwards
+ compatibility issues, MongoCollection::deleteIndex
+ cannot delete custom-named indexes as well. Thus, the best way to delete
+ indexes created in the shell or with custom names is to directly call the
+ deleteIndexes database command.
+
+
+ Thus, if you named an index "superfast query", you could delete it with:
+
+
+command(array("deleteIndexes" => $collection->getName(), "index" => "superfast query");
+
+?>
+]]>
+
+
+ To find what an index is named, you can query the
+ system.indexes collection of a database and look for the
+ name field.
