我想在我的程序中释放ram.
即使我是新手,我也非常关心性能.
string i_want_to_delete_this = "I don't want this cleared, but
completely gone";
/* I figured out */ i_want_to_delete_this.clear() /* simply sets the
string value to "". I want to be able to do this with every
datatype! I want it completely gone, not even declared anymore. */
Run Code Online (Sandbox Code Playgroud) 我想在Windows 10 Pro上安装PHP,我尝试从官方网站下载PHP 7.1和7.0.14,但由于某种原因我在下载的文件夹中找不到php.exe(似乎没有完全可执行)。
我在哪里可以找到二进制文件?我的目标是能够从命令提示符运行 PHP。
