New version of Ueditor under php7
In the version of php7.0, part of Ueditor function is useless. In addition, JS is also wrong in order to upload multiple maps.
UeditorRandom number function
$randNum = rand(1, 10000000000) . rand(1, 10000000000);
The value range is too large, exceeding the range of int, resulting in errors.
After uploading the file, the generated file name is wrong, causing adverse reactions.
The following is changed, and the JS problem of sorting is also adjusted.

The use of broadcast variables – which province is it querying through IP?
1，Why broadcast variables?
To give a simple example, we have to deal with a log file with IP address.
20090121000132095572000|125.213.100.123|show.51.com|/shoplist.php?phpfile=shoplist2.php&style=1&s
We can get IP through segmentation. Now we are asked to get the IP province from this IP. The IP rules are as follows (a small part):
1.0.1.0|1.0.3.255|16777472|16778239|Asia, China, Fujian, Fuzhou, China Telecom |350100|China|CN|119.306239|26.0753021.0.8.0|1.0.15.255|16779264|16781311|Asia, China, Guangdong, Guangzhou, China Telecom |440100|China|CN|113.280637|23.1251781.0.32.0|1.0.63....
