• what is the difference between plugin and library?

  - by fayer

  i wonder what the difference between a library and a plugin is? if a component creates a database (maybe comes with a .sql file or creates through a method) could it still be a library or is it called a plugin or module? cause i am creating a address book component and it provides methods to insert and read records in database. i don't know if i should put it in library folder or plugin folder. please shed a light on this. thanks

• php read CSV with various amount of delimiters

  - by jreed121

  I've got a script that reads in from a CSV file and sometimes the CSV files it receives contains an uneven amount of delimiters/columns so the first row could have 30 columns, the 2nd could have 20, etc. I can think of a few solutions myself ie: Count the delimiters in the widest row, then append the proper amount to each row that is short to make them even. But I was wondering if anyone had a more elegant method of doing this.

• How can I get access to spring container?

  - by Antony

  I have a spring container running, and I have class with which I want to have access to the bean created inside spring container. The class I have is not registered with the spring container. One thing I can do is that I can use MethodInvoker to call a static method, so I will have access to static field (this would be a bean from spring container) in my class always. Do we have class like WebapplicationContextUtils for a application that is not web?

  What I want to do is provide some public static fields that will be used as instances of an interface implementation and have intellisense pick them up when the interface is a method argument.
