The previous output looked nothing like var_dump(). The indexes are are comparable to those in the previous example, although there are some additional fields and I changed the geo-spatial index to "2dsphere". git-svn-id: https://svn.php.net/repository/phpdoc/en/trunk@335757 c90b9560-bf6c-de11-be94-00142212c4b1

This function returns an array in which each element describes an index.
|
|
Elements will contain the values <literal>name</literal> for the name of
|
|
the index, <literal>ns</literal> for the namespace (a combination of the
|
|
database and collection name), and <literal>key</literal> for a list of all
|
|
fields in the index and their ordering. Additional values may be present for
|
|
special indexes, such as <literal>unique</literal> or
|
|
<literal>sparse</literal>.
