Timeouts

CURLOPT_CONNECTTIMEOUT is a maximum amount of time in seconds to which a connection attempt will be restricted for a cURL operation. ft can be set to 0 to disable this limit, but this is inadvisable in a production environment. Note that this time includes DNS lookups. For environments where the DNS server in use or the web server hosting the target application is not particularly responsive, it may be necessary to increase the value of this setting.

CURLOPT_TIMEOUT is a maximum amount of time in seconds to which the execution of individual cURL extension function calls will be limited. Note that the value for this setting should include the value for CURLOPT_CONNECTTIMEOUT. In other words, CURLOPT_CONNECTTIMEOUT is a segment of the time represented by CURLOPT_TIMEOUT, so the value of the latter should be greater than the value of the former.
