fetch_url is deprecated and being replaced by the more capable z_fetch_url please use that function instead. Once all occurrences of fetch_url are removed from the codebase we will remove this function and perhaps rename z_fetch_url back to fetch_url

xml2array	(	$contents,

xml2array() will convert the given XML text to an array in the XML structure. Link: http://www.bin-co.com/php/scripts/xml2array/ Portions significantly re-written by mike@.nosp@m.macg.nosp@m.irvin.nosp@m..com for Friendica (namespaces, lowercase tags, get_attribute default changed, more...) Arguments : $contents - The XML text $namespaces - true or false include namespace information in the returned array as array elements. $get_attributes - 1 or 0. If this is 1 the function will get the attributes as well as the tag values - this results in a different array structure in the return value. $priority - Can be 'tag' or 'attribute'. This will change the way the resulting array sturcture. For 'tag', the tags are given more importance. Return: The parsed XML in an array form. Use print_r() to see the resulting array structure. Examples: $array = xml2array(file_get_contents('feed.xml')); $array = xml2array(file_get_contents('feed.xml', true, 1, 'attribute'));

z_fetch_url

Parameters

string	$url	URL to fetch
boolean	$binary	= false TRUE if asked to return binary results (file download)
int	$redirects	= 0 internal use, recursion counter
array	$opts	(optional parameters) 'accept_content' => supply Accept: header with 'accept_content' as the value 'timeout' => int seconds, default system config value or 60 seconds 'http_auth' => username:password 'novalidate' => do not validate SSL certs, default is to validate using our CA list

Returns: array 'return_code' => HTTP return code or 0 if timeout or failure 'success' => boolean true (if HTTP 2xx result) or false 'header' => HTTP headers 'body' => fetched content
