compatible_gzinflate()
Decompression of deflated string while staying compatible with the majority of servers.
public
static compatible_gzinflate(string $gz_data) : string|bool
Certain Servers will return deflated data with headers which PHP's gzinflate() function cannot handle out of the box. The following function has been created from various snippets on the gzinflate() PHP documentation.
Warning: Magic numbers within. Due to the potential different formats that the compressed data may be returned in, some "magic offsets" are needed to ensure proper decompression takes place. For a simple progmatic way to determine the magic offset in use, see: https://core.trac.wordpress.org/ticket/18273
Parameters
- $gz_data : string
-
String to decompress.
Tags
Return values
string|bool —False on failure.
decompress()
Decompress an encoded body
public
static decompress(string $data) : string
Implements gzip, compress and deflate. Guesses which it is by attempting to decode.
Parameters

-
Compressed data in one of the above formats

request()
Main interface for HTTP requests
public
static request(string|Stringable $url[, array<string|int, mixed> $headers = [] ][, array<string|int, mixed>|null $data = [] ][, string $type = self::GET ][, array<string|int, mixed> $options = [] ]) : Response
This method initiates a request and sends it via a transport before parsing.
The $options
parameter takes an associative array with the following
options:
-
timeout
: How long should we wait for a response? Note: for cURL, a minimum of 1 second applies, as DNS resolution operates at second-resolution only. (float, seconds with a millisecond precision, default: 10, example: 0.01) -
connect_timeout
: How long should we wait while trying to connect? (float, seconds with a millisecond precision, default: 10, example: 0.01) -
useragent
: Useragent to send to the server (string, default: php-requests/$version) -
follow_redirects
: Should we follow 3xx redirects? (boolean, default: true) -
redirects
: How many times should we redirect before erroring? (integer, default: 10) -
blocking
: Should we block processing on this request? (boolean, default: true) -
filename
: File to stream the body to instead. (string|boolean, default: false) -
auth
: Authentication handler or array of user/password details to use for Basic authentication (\WpOrg\Requests\Auth|array|boolean, default: false) -
proxy
: Proxy details to use for proxy by-passing and authentication (\WpOrg\Requests\Proxy|array|string|boolean, default: false) -
max_bytes
: Limit for the response body size. (integer|boolean, default: false) -
idn
: Enable IDN parsing (boolean, default: true) -
transport
: Custom transport. Either a class name, or a transport object. Defaults to the first working transport from Requests::getTransport() (string|\WpOrg\Requests\Transport, default: Requests::getTransport()) -
hooks
: Hooks handler. (\WpOrg\Requests\HookManager, default: new WpOrg\Requests\Hooks()) -
verify
: Should we verify SSL certificates? Allows passing in a custom certificate file as a string. (Using true uses the system-wide root certificate store instead, but this may have different behaviour across transports.) (string|boolean, default: certificates/cacert.pem) -
verifyname
: Should we verify the common name in the SSL certificate? (boolean, default: true) -
data_format
: How should we send the$data
parameter? (string, one of 'query' or 'body', default: 'query' for HEAD/GET/DELETE, 'body' for POST/PUT/OPTIONS/PATCH)
Parameters
- $url : string|Stringable
-
URL to request
- $headers : array<string|int, mixed> = []
-
Extra headers to send with the request
- $data : array<string|int, mixed>|null = []
-
Data to send either as a query string for GET/HEAD requests, or in the body for POST requests
- $type : string = self::GET
-
HTTP request type (use Requests constants)
- $options : array<string|int, mixed> = []
-
Options for the request (see description for more information)

Return values
Responserequest_multiple()
Send multiple HTTP requests simultaneously
public
static request_multiple(array<string|int, mixed> $requests[, array<string|int, mixed> $options = [] ]) : array<string|int, mixed>
The $requests
parameter takes an associative or indexed array of
request fields. The key of each request can be used to match up the
request with the returned data, or with the request passed into your
multiple.request.complete
callback.
The request fields value is an associative array with the following keys:
-
url
: Request URL Same as the$url
parameter to Requests::request() (string, required) -
headers
: Associative array of header fields. Same as the$headers
parameter to Requests::request() (array, default:array()
) -
data
: Associative array of data fields or a string. Same as the$data
parameter to Requests::request() (array|string, default:array()
) -
type
: HTTP request type (use \WpOrg\Requests\Requests constants). Same as the$type
parameter to Requests::request() (string, default:\WpOrg\Requests\Requests::GET
) -
cookies
: Associative array of cookie name to value, or cookie jar. (array|\WpOrg\Requests\Cookie\Jar)
If the $options
parameter is specified, individual requests will
inherit options from it. This can be used to use a single hooking system,
or set all the types to \WpOrg\Requests\Requests::POST
, for example.
In addition, the $options
parameter takes the following global options:
-
complete
: A callback for when a request is complete. Takes two parameters, a \WpOrg\Requests\Response/\WpOrg\Requests\Exception reference, and the ID from the request array (Note: this can also be overridden on a per-request basis, although that's a little silly) (callback)
Parameters
- $requests : array<string|int, mixed>
-
Requests data (see description for more information)
- $options : array<string|int, mixed> = []
-
Global and default options (see Requests::request())
