This was an enormously helpful link to find:
http://php.net/manual/en/migration56.openssl.php
An official document describing the changes made to open ssl in PHP 5.6 From here I learned of one more parameter I should have set to false: “verify_peer_name”=>false
So my working code looks like this:
<?php
$arrContextOptions=array(
"ssl"=>array(
"verify_peer"=>false,
"verify_peer_name"=>false,
),
);
$response = file_get_contents("https://maps.co.weber.ut.us/arcgis/rest/services/SDE_composite_locator/GeocodeServer/findAddressCandidates?Street=&SingleLine=3042+N+1050+W&outFields=*&outSR=102100&searchExtent=&f=json", false, stream_context_create($arrContextOptions));
echo $response; ?>
