The following repository access (RA) modules is available:

• Ra_neon:module for accessing a repository via WebDAV protocol using neon.
  
  
  • handles ' http ' scheme
  • handles ' https ' scheme
• Ra_svn:module for accessing a repository using the SVN network protocol.
  
  
  • with Cyrus SASL authentication
  • handles ' svn ' scheme
• ra_l Ocal:module for accessing a repository on local disk.
  
  
  • handles ' file ' scheme

Replace the second line of code with
popen('svn up --username zmk --password 123456 /home/wwwroot/test/','r');
(Nothing is output).
If you replace the second line of code with
popen('svn up --username zmk --password 123456 /home/wwwroot/xxx/','r');
Here /home/wwwroot/xxx is the wrong address, the final page will be output
Skipped '/home/wwwroot/xxx'

Ask the god of Linux to see
