this issue has become clear:
while file_get_contents not working,
run shell command:
#curl -I www.bing.com
curl: (7) Failed to connect to 2001:4870:a14a:100::cebe:4fd2: Network is unreachable
www.bing.com is an alias for a134.dsw3.akamai.net.
a134.dsw3.akamai.net has address 188.8.131.52
a134.dsw3.akamai.net has IPv6 address 2001:4870:a14a:100::cebe:4fd9
a134.dsw3.akamai.net has IPv6 address 2001:4870:a14a:100::cebe:4fd2
#curl -I -H "host:www.bing.com" 184.108.40.206
curl: (7) couldn't connect to host
so it's clear that accessing to www.bing.com
too frequently(in php script) has caused the server's IP banned by bing. Usually IP banned for some time temporarily. after some time, can access bing again.
