VS automatically downloads NuGet-managed libraries during compilation, vs compiles nuget
Previously, NuGet has been used to manage some third-party libraries. However, each check in code must be checked in to ensure that the compilation is passed.
It is time-consuming, especially to synchronize code to github, and these libraries are available on NuGet, so there is no need to check in.
At the request of a large number of people, NuGet began to supp

Php downloads the image address from the collected content and replaces the local address,
Get all the addresses in the string to an array. We use the preg_match_all function.
The Code is as follows:$ Str = '$ Pattern = "/Preg_match_all ($ pattern, $ str, $ match); print_r ($ match );?>
Result
Array([0] => Array([0] => )[1] => Array([0] => upfiles/2009/07/1246430143_1.jpg))
With the core functions above, we can do the following.
