This article mainly introduces about PHP according to latitude and longitude sorting, according to latitude and longitude to filter the distance segment, has a certain reference value, now share to everyone, the need for friends can refer to SQL statements: Select Location.* from (select *,round (6378.138*2*asin (sqrt () (Pow () (Sin (36.668530*pi ()/180-px_lat*pi ()/180)/2), 2) +cos (36.668530*pi ()/180) *cos (Px_lat*pi ()/180) * POW (Sin ((117.020359*pi ()/180-px_lon*pi ()/180)/2), 2)) (*1000

great iPhone product, 2/3 of mobile phone terminals, Web browsing from iPhone or iPod. At, Beijing time, huzzah software came. Using iPhone accessories and using the iPhone as a guitar amplifier may seem boring to everyone. Now, 90% of the people present need to be patient, haha. The Zipcar software, which uses the iPhone to remotely monitor your car and learn about its location and embedded Google Maps, is introduced at am Beijing time. You

To travel in the United States, renting a car should be a good choice.There are domestic rental car rentals available, or rent a car directly in Alamo,enterprise,national, USA. These are all a family. Affiliated to Https://en.wikipedia.org/wiki/Enterprise_HoldingsHertz,avis,zipcar is also an American car rental company.Vehicle information can be obtained by license plate or VIN on the following website.http://www.autocheck.com/vehiclehistory/autocheck

when the left and right sides are generated. Only the accuracy changes, and the latitude remains unchanged. Therefore, you only need to generate the upper and lower latitudes to ensure the accuracy of the left and right sides. According to the article on the internet, http://digdeeply.info/archives/06152067.html this article is achieved by using PHP longitude and latitude query. The Code modified to java is as follows: [Java] view plaincopy/*** Generate a quartile longitude and latitude centere

, etc.), the more it means that you can take advantage of the chain reaction between consumers to help you take on 90% of your marketing costs.ConclusionIn many cases, the density of consumers in the same market is a key factor in business success.Because once a market, with similar products to meet the similar needs of consumers more than a certain threshold (such as 100 people in the use of 15), the impact of consumer interaction, opinion reference will form a chain reaction, the entire market

costs may easily exceed billion dollars! In fact, in the Internet entrepreneurship field, we often lament that many companies in Silicon Valley are more imaginative than us, such as my favorite ifttt, Airbnb, Zipcar, Twitter, Pinterest, google Glass, Siri... This time I chatted with a group of students, such as Stanford, ucia, and Berkeley, who came out to start a business in Silicon Valley. They had an interesting point. They believe that there are

Thinkphp implements nearby queries, such as nearby people and nearby deals.First, you want to locate the latitude and longitude of the user. The client-side targeting method can be located using the Map API or with the HTML5 browser (less stable and less precise).Then, the current latitude and longitude, and the distance required to search, calculate a latitude and longitude range, this range is "nearby." An example of this "nearby" is calculated as follows:/** * * @param $latitude latitude * @p
