A PHP script, through Curl first get Baidu Map API generated latitude and longitude, and then change the data in the database.

Write a PHP script today to starters the region name of the response from the database and then query the name of the kindergarten for accurate latitude and longitude. Each time the resulting latitude and longitude enters the changes in the database.

Over 70,000 data takes one hours to complete. I have to say that curl results more quickly than file_getcoents. Not much to say directly on the code
