I tried TRAC before and knew how powerful it is But I'm having lots of difficulties to to put it on an online host, it needs lots of resources and can't put it on a regular paid host
So I wanted to know if there is a TRAC-Like but written with PHP or something, I need it to have SVN, Wiki, Ticket issuing and maybe Forums
If you have Ruby on Rails support, you might take a look at Redmine. It has all of the features that you require. I've recently started using it and have been pretty happy with it. I was never able to find one written in PHP that suited my needs.
I used to have same issue, but I badly wanted Trac and nothing else. I finally rented a small Windows-based virtual server at €20/month (the linux ones are cheaper) on which I do all my development stuff: Subversion, a test Apache environment, and Trac. It takes some time to set up, but I'm quite happy with it and can recommend it. Also, on standard shared hosting, your problems might not end with Trac: Subversion is a rarity among hosting providers as well. Depending on where you are based, e.g. 1and1 rent cheap virtual servers in europe and the US.
