Development directory Structure [closed]

Answer 1

After a couple years working with different structures I recently found a structure that hols most variations for me:

/project_name     (everything goes here)
  /web            (htdocs)
    /img
    /css
  /app            (usually some framework or sensitive code)
  /lib            (externa libs)
    /vendor_1
    /vendor_2
  /tmp
    /cache
  /sql            (sql scripts usually with maybe diagrams)
  /scripts
  /doc            (usually an empty directory)
