Overview

eac_curl.class.php and eac_streams.class.php are wrapper classes for using curl or streams to make http GET, POST, or PUT requests.

New in curl.class v0.7.4 and streams.class v0.3.4 -
HEAD, DELETE, OPTIONS, and TRACE requests

eac_curl.class.php accepts any of the curl_setopt options - although not all are applicable to this class.

eac_streams.class.php is intended to be a plug-in replacement for eac_curl.class.php that can be used when the curl library is not configured in the PHP implementation. It accepts a subset of the curl_setopt options and will ignore curl options that are not applicable.

One advantage that eac_streams.class.php has over eac_curl.class.php is the "STREAMS_ASYNCRONOUS" option. When set to 1 or true, the streams process will not wait for the response from the http request and thus execute the request asyncronously.

Either class will recognize option names with "CURL_" or "STREAMS_" prefix.

Both classes support, recognize, and decode gzip encoding (compression) reducing the content length of the response by up to 80%.

Common Methods:

setOptions() - set a array of options.
setOption() - set a single option.
setCallback() - set a callback function.
copyHeaders() - copy the http request headers to send with this request.
header() - set an http header.
copyCookies() * - copy the http request cookies to send with this request. *
head() * - send an http HEAD request.
get() - send an http GET request.
post() - send an http POST request.
put() - send an http PUT request.
delete() * - send an http DELETE request.
options() * - send an http OPTIONS request.
trace() *- send an http TRACE request.
httpRequest() - send an http request (used by get(), post(), and put()).
sendLastResult() - sends the result of the last request via email.
getLastResult() - returns the result of the last request.
getInfo() - returns a status array of the last request (i.e. curl_getinfo()).
getHeaders() - returns the response headers of the last request.
getOptions() - returns the current options array.
