MongoCollection::deleteIndexes - Delete all indices for this collection

SYNOPSIS

       public array MongoCollection::deleteIndexes (void  )

DESCRIPTION

PARAMETERS

       This function has no parameters.

RETURN VALUES

	Returns the database response.

EXAMPLES

       Example #1

	      MongoCollection.deleteIndexes(3) example

	      This example demonstrates how to delete all indexes from a collection and the response to expect.

	      <?php

	      $collection = $mongo->my_db->articles;
	      $response = $collection->deleteIndexes();
	      print_r($response);

	      ?>

	      The above example will output something similar to:

	      Array
	      (
		  [nIndexesWas] => 1
		  [msg] => all indexes deleted for collection
		  [ok] => 1
	      )

The MongoCollection class

INTRODUCTION

	Represents a MongoDB collection.

	Collection names can use any character in the ASCII set. Some valid collection names are "", "...", "my collection", and "*&#@".

	User-defined  collection  names  cannot  contain  the  $  symbol. There are certain system collections which use a $ in their names (e.g.,
       local.oplog.$main), but it is a reserved character. If you attempt to create and use a collection with  a  $  in  the  name,  MongoDB  will
       assert.

FIELDS

	      o $db
		- The "parent" database for this collection.

	      o $w
		-  The	number of servers to replicate a change to before returning success. Value is inherited from the parent database. The Mon-

	      o $wtimeout
		- The number of milliseconds to wait for $this->w replications to take place. Value is inherited from  the  parent  database.  The
