Is there a good open source script/library for php, that will produce cryptographic secure Pseudo-Random-Numbers?
At http://php.net/manual/en/function.mt-rand.php, there is a warning that says, "This function does not generate cryptographically secure values, and should not be used for cryptographic purposes. If you need a cryptographically secure value, consider using openssl_random_pseudo_bytes() instead". See http://php.net/manual/en/function.openssl-random-pseudo-bytes.php.
Probably the best way is to simply read from /dev/urandom, but a plethora of examples can be found in this article (sorry for the non SO link):
http://timoh6.github.io/2013/11/05/Secure-random-numbers-for-PHP-developers.html
There is also a php library if this is what you are looking for:

Are there any popular PHP libraries or services that can help detect duplicate content?
I run a site that has user generated content and I want to detect content that are similar or duplicated. Are there any popular libraries out there that can help with this?
Text similarity/plagiat/duplicate is a big topic. There are so many algos and solutions.
Some projects use the "adaptive local alignment of keywords" (you will find info on that on google.)
Also, you can check this (Check the 3 links in the answer, very instructive):
Cosine similarity vs Hamming distance
Hope this will help.

I'm looking for an secure php usermanagement system. It should be just the logics, so no markup or too much content (like messages etc.). I know I could just build it myself, but I doubt if it will be the most effecient usermanangement system.
The system should be at least
able to verify if the user is human
very secure (security against hacks, but also protect the users from their stupidity)
effecient (number of users will start at 1k and from then grow exponentially to around 100k)
capable of handling roles and capabilities
You guys got any recommandations?
You can use any of the following scripts:
http://sourceforge.net/projects/phploginsystemw/ (Login with 5 levels of security)
http://usercake.com/
http://www.downscripts.com/user-management-script_php-script.html
http://userpie.com/
http://gscripts.net/free-php-scripts/Login_Management/PHP_Login_Script/details.html
http://www.webresourcesdepot.com/free-php-user-management-script-log-me-in/
You should probably take a look at this:
http://www.hotscripts.com/category/scripts/php/scripts-programs/user-management/
I have use this before:
http://sourceforge.net/projects/phploginsystemw/
worked for me.
Take a look at drupal. It is a framework with modules for this stuff. You will be able to get away with very minimal coding.

i've found one cheat sheet for doctrine: cheat sheet
but it doesn't list all methods for Doctrine_Record, Doctrine_Core, Doctrine_Query etc.
i wonder if there is a such reference?
Would be very helpful.
I don't think so, 'cause such cheat sheets should contain only the most popular, useful methods and informations. But Doctrine's API is documented, so why don't you use official Doctrine API Documentation.
I find myself using the source itself as documentation when I need it. It's quite readable. Alternatively use something like http://www.phpdoc.org/ to make it more so.

I'm looking for some software that will allow me to do the following:
alt text http://patrickg.net/lookingfor.png
I don't need anything fancy, just basic information, back and forth dated comments, etc. No payment integration, or file handling.
Thought I'd ask before I write my own
Good luck with that - but from what I've seen, most of the stuff out there have x100 more features, and an appropriate learning curve. I don't know if you can find something with the exact features you've asked.
What's the problem with rolling your own, though? As long as you use a framework, isn't it just a couple days' work (maybe even a day)? Learning/using a full-fledged CMS might take more time.
This may be overkill, but you may want to take a look at SugarCRM

Where can I find a one-page (any size) cheat sheet of PHP functions, syntax, and block constructs?
You mean something like a Cheat Sheet?
There's also a great page for the results of variable tests that I find very useful.
You may find a lot of PHP cheat sheets on TechPosters website.
PCRE, Smarty, PHP
WordPress, MySQL, Smarty...
PHP ( date formatting, regex...)
http://www.addedbytes.com/cheat-sheets/php-cheat-sheet/
is more complete, but I think
http://www.addedbytes.com/cheat-sheets/php-cheat-sheet-version-1/
spaces it out more
These reference charts are usually referred to as cheatsheets.
Here are a few links, but Google will turn up many others:
