问题
I'm planning to use the Google Maps V3 API to geocode a batch of address stored in an array. These address will be retrieved from my database and geocoded so I can create markers for them on the map.
However I understand that Google has placed a limit on the rate of geocoding requests sent to them, so I am wondering how I can use PHP to limit the rate of geocoding requests, to maybe 1 geocode every 10 seconds?
sleep(10);?
回答1:
Yep, sleep(10) would do that.
Alternatively, run the geocoding using javascript on the client machine. The rate limiting is based on the IP address, so you can spread this out over your visitors by having their browser do the geocode.
