get_resources — Returns active resources

### Description

array get_resources ([ string `$type` ] )

Returns an array of all currently active resources, optionally filtered by resource type.

### Parameters

`type`

  If defined, this will cause get_resources() to only return resources of the given type. A list of resource types is available.

  If the string Unknown is provided as the type, then only resources that are of an unknown type will be returned.

  If omitted, all resources will be returned.

### Return Values

Returns an array of currently active resources, indexed by resource number.

### Examples

Example #1 Unfiltered get_resources()

`<?php
$fp = tmpfile();
var_dump(get_resources());
?>`

The above example will output something similar to:

    array(1) {
      [1]=>
      resource(1) of type (stream)
    }

Example #2 Filtered get_resources()

`<?php
$fp = tmpfile();
var_dump(get_resources('stream'));
var_dump(get_resources('curl'));
?>`

The above example will output something similar to:

    array(1) {
      [1]=>
      resource(1) of type (stream)
    }
