Answer 1

I got some test code working using yours as a basis and the only issue I found was this line.

CURLOPT_POSTFIELDS => urlencode('ctl00%24scriptManager=ctl00%24cphMainContent%24ctl00%24cphMainContent%24rdpMembersPanel%7C' . $pageNumberCodes[0] . '&__EVENTTARGET=' . $pageNumberCodes[0] . '&__EVENTARGUMENT=' . '&__VIEWSTATE=' . $viewstate . '&__EVENTVALIDATION=' . $eventvalidation . "&google=" . '&ctl00%24cphMainContent%24txtZip=' . '&ctl00%24cphMainContent%24cboRadius=Exact' . '&ctl00%24cphMainContent%24txtMemberName=' . '&ctl00%24cphMainContent%24txtCity=Honolulu' . '&ctl00%24cphMainContent%24cboState=HI' . '&ctl00%24cphMainContent%24txtAddress=' . '&ctl00_cphMainContent_rdpMembers_ClientState=' . '&ctl00%24cphMainContent%24ddList=-Select%20field%20to%20sort-' . '&ctl00_cphMainContent_ddList_ClientState=' . '&ctl00_cphMainContent_rdlMembers_ClientState=' . '&ctl00_cphMainContent_ddList_ClientState=' . '&ctl00_cphMainContent_rdlMembers_ClientState=' . '&ctl00_cphMainContent_rdpMembers1_ClientState=' . '&__ASYNCPOST=true' . 'RadAJAXControlID=ctl00_cphMainContent_RadAjaxManager1')

would need the urlencode moved to look like so

CURLOPT_POSTFIELDS => 'ctl00%24scriptManager=ctl00%24cphMainContent%24ctl00%24cphMainContent%24rdpMembersPanel%7C' . $pageNumberCodes[0] . '&__EVENTTARGET=' . $pageNumberCodes[0] . '&__EVENTARGUMENT=' . '&__VIEWSTATE=' . rawurlencode($viewstate) . '&__EVENTVALIDATION=' . rawurlencode($eventvalidation) . "&google=" . '&ctl00%24cphMainContent%24txtZip=' . '&ctl00%24cphMainContent%24cboRadius=Exact' . '&ctl00%24cphMainContent%24txtMemberName=' . '&ctl00%24cphMainContent%24txtCity=Honolulu' . '&ctl00%24cphMainContent%24cboState=HI' . '&ctl00%24cphMainContent%24txtAddress=' . '&ctl00_cphMainContent_rdpMembers_ClientState=' . '&ctl00%24cphMainContent%24ddList=-Select%20field%20to%20sort-' . '&ctl00_cphMainContent_ddList_ClientState=' . '&ctl00_cphMainContent_rdlMembers_ClientState=' . '&ctl00_cphMainContent_ddList_ClientState=' . '&ctl00_cphMainContent_rdlMembers_ClientState=' . '&ctl00_cphMainContent_rdpMembers1_ClientState=' . '&__ASYNCPOST=true' . 'RadAJAXControlID=ctl00_cphMainContent_RadAjaxManager1'
