RE: [PEAR] What is the necessity to use a installer to install php pear (Some more questions)

Hi Justin Thank You. I am much satisfied with ur answers. Still I Have some more questions ( It may be silly but please.......... ) 1)Pear Packages are being modified time to time a)Will they add only additional packages or even they modify the old packages b)If they also modify the old packages will they make changes in the old methods or they only add new methods (why i am asking is Do i want to study different different methods on different versions for doing the same purpose) 2)We are using PEAR in our project but the server where we need to upload our project does not contail pear (ie PEAR is not installed) what will happen 3)Suppose if we are using the resent version of PEAR but the server what we are uploading only contains the old version of PEAR what will happen 4)Is it necessary the PEAR version what we are using in our project should be the same in the server where we have to upload the projet 5)When we are uploding our project in the server is it necessary to check wheather the server contains pear and the version of pear installed in that server is same as what we are using. 6)If so how to check one sample coding please... regards moses > -------- Original Message -------- > Subject: Re: [PEAR] What is the necessity to use a installer to install > php pear > From: "Justin Patrin" <papercrane@gmail.com> > Date: Sun, May 07, 2006 10:03 pm > To: "moses@softwaysolutions.com" <moses@softwaysolutions.com> > Cc: pear-general@lists.php.net > > On 5/7/06, moses@softwaysolutions.com <moses@softwaysolutions.com> wrote: > > > > Hi everybody > > > > I am new to pear... and i have some doubts regarding installing pear > > Doubts?
