i am trying to convert these urls
localhost/list/data/?search=keyword
localhost/list/data?search=keyword
to
localhost/list/data/search/keyword
i used this expression
(.+)(\?|\/\?)([a-z0-9_-]+)=([a-z0-9_-]+)
the problem is suppose that the user searches for another keyword
localhost/list/data/search/keyword/?search=anotherkeyword
localhost/list/data/search/keyword?search=anotherkeyword
it becomes like this
localhost/list/data/search/keyword/search/anotherkeyword
how can make it like this
localhost/list/data/search/anotherkeyword
where in it replaces the previous search/keyword in the url
Its a little more complicated than just regex. The best approach is a combination of server side scripting, and htaccess. I wrote up an answer for a very similar question not to long ago. As well as use this solution in a handful of sites I develop.

I'm not asking for a whole engine of code. I'm working on a blog/magazine website. Here are the 2 styles of paginations. I see people use these types of addresses:
example.com/browse?page=100
example.com/page/100/
I understand 1.'s. But, 2. doesn't give me an impression of php usage in the address.
I did a search on Google, but there are only helps on 1. How do you manage 2.? Because whenever you write a new article, you have to push the content throughout every html? Did they use "fake addresses"? because I tried example.com/page/100/index.html and there is no such website.
Can anyone point me to a webpage or explain to me how did they manage 2. style of pagination? Which has a better UX?
Sorry if this is a bad title. Please help me edit and ask me if anywhere isn't clear.
It's URL Rewriting that is responsible or translating nice-looking Urls to their 'real' path on the server.
In your case,
www.example.com/page/100/
might be rewritten on the server to something like
www.example.com/browse.php?page=100

I'm building a simple web crawler and I'm trying to filter links based on whether or not they've been seen before. The issue is that a link might be the same, but with a forward slash, arguments. I also would like to filter out mail to's. Is there any known, straightforward to do this? I'm currently working in pHp.
Edit:
I used Net_URL2.php to normalize the URL's after viewing this:
How do I apply URL normalization rules in PHP?
Short answer is no, there's no straight way to do that. Have a read at this article about URL normalization to find out some reasons why that is hard to accomplish.

The only way I know to pass parameters in the URL is using the GET method in PHP. But I saw many websites using what seems to be parameters directly in the URL, like this:
http://.../page/2/
In this case, is "page" really a parameter? If so, how is it handled in the code?
Or is this a regular URL of a directory "2" located in a directory "page"? Would it mean that whenever a new post is created, the website creates all the pages and the corresponding directories?
Thanks
This is called url rewriting. Basically this means that you use an apache module to rewrite incoming urls to new urls which are then handled by apache
In your example http://www.test.com/page/2/ is probably rewritten to something like http://www.test.com/?page=2.
If you search the internet for Apache URL rewrite you will get enough results explaining how you can do this.
These are all conventions. GET parameters are not specific to PHP, this is how all browsers encode form data. Java-based webapps use semicolon-separated parameters for example.
You can write a simple layer to convert ?alpha=1&beta=2 to /alpha/1/beta/2 but iw tould be just a cheap gimmick (except in a very few legitimate cases like with Squid caches).
What today's websites do is to use a single entry point pattern. Usually with apache's mod_rewrite, all requests are handled by the index.php and there is a routing facility to choose the adequate handler PHP file for a specific URL scheme. These schemes can be easily defined by Regular Expressions.
So all in all you decide how your URLs are going to look like. It is not an easy task and there are many SEO snake oil salesmen out there who will make you do all kinds of crazy stuff. What a good URL does is to identify a content (document) inside your service and you must use that single URL throughout your service to address it.
And don't forget: cool URLs don't change. You will abandon your current code base in 2 years and rebuild your site from the ground up. Design your URL scheme in a way that makes sense from a logical point of view and not something dependent on your webapp design.
The example you gave is still a GET request.
What you are looking for is URL rewriting.
Consider a situation of a URL as:
www.example.com/softwares/download.php?f=firefox&v=13
It does not look as good as URL:
www.example.com/softwares/firefox/download?v=13
or same download.php used as:
www.example.com/softwares/chrome/download?v=20
How can I achieve this type of URL filtering in PHP?
Some point I want to covered here:
I don't need a folder-hierarchy here like having different folders for /firefox/ and different for /chrome/
There could be only two PHP files (as I wish to) for all products: /software/software-info.php and /software/download.php (already got here).
I am able to put and fetch information from database in PHP but just want to have different link for different product.
I am a Java Web Developer in which you have Filters to get information from a part of link and redirect the request accordingly.
I am new in PHP programming and if this question is already asked or obvious than please pardon me and provide that question link.
This is ideally what you should use url rewriting (mod-rewrite in .htaccess) for.
Your visitor navigates to:
www.example.com/softwares/firefox/download?v=13
or even
www.example.com/softwares/firefox/13/
but your server will understand it as:
www.example.com/softwares/download.php?f=firefox&v=13
You can use htaccess files to do URL rewriting. Essentially this would allow you to take the segments of the url after /software/ and pass them ass parameters to be controlled by the software script.
There are also a bunch of PHP frameworks which use 'routes'. They're based on a similar principal as URL rewriting. I'd recommend Codeigniter as a good starting point - it's a straightforward framework, which plenty of documentation and tutorials.
Good luck!
I have posted a similar question here. However, this was more about getting advice on what to do. Now that I know what to do, I am looking for a little help on how to do it!
Basically I have a website that is pretty much 100% dynamic. All the website links are generated using PHP and all the pages are made up of php includes/code. I am trying to improve the SEO of the site by improving the URLs (as stated in the other question) and I am struggling a little.
I am using mod_rewrite of rewriting the nice urls to the ugly urls on the server. So what I need is to now convert the ugly urls (which are generated from the php code in the pages) to the nicer urls.
Here are the URLs I need to parse (these are in the other question aswell):
/index.php?m=ModuleType
/index.php?m=ModuleType&categoryID=id
/index.php?m=ModuleType&categoryID=id&productID=id
/index.php?page=PageType
/index.php?page=PageType&detail=yes
Here is what I want the above URLs to be parsed to:
/ModuleType
/ModuleType/CategoryName
/ModuleType/CategoryName/ProductName
/PageType
/PageType/Detail
There is an example on the other question posted by Gumbo however I felt it was a bit messy and unclear on exactly what it was doing.
Could someone help me solve this problem?
Thanks in advance.
I think I see what you're after... You've done all the URL rewriting, but all the links between your pages are using the old URL syntax.
The only way I can see around this is to do some kind of regex search and replace on the links so they use the new syntax. This will be a bit more complicated if all the links are dynamically generated, but hopefully there won't be too much of this to do.
Without seeing how your links are generated at the moment, it's difficult to say how to change the code. I imagine it works something like this though:
<?php echo "<a href='/index.php?m=$ModuleType&categoryID=$id'>"; ?>
So you'd change this to:
<?php echo "<a href='$ModuleType/$id'>"; ?>
Sorry if I've made errors in the syntax, just off the top of my head...
Unless I misunderstood your question, you don't parse the "ugly" URLs, your PHP script is called with them, so you $_GET[] your parameters (m, categoryID, productID) and you combine them to make your nice URLs, which shouldn't be too hard (just a bit of logic to see if one parameter is there and concatenate the strings).
You will need a front controller, which will dispatch the URL to the correct page.
Apache will rewrite the URL using rules in .htaccess, so that anything written will be redirected to index.php?q=. For example, typing http://example.com/i/am/here will result in a call to index.php?q=/i/am/here
Index.php will parse the path from $_GET["q"] and decide what to do. For example, it may include a page, or go to the database, look the path up, get the appropriate content and print it out
If you want a working example of a .htaccess which will do exactly that (redirect to index.php with ?q=path) take a look at how drupal does it:
http://cvs.drupal.org/viewvc.py/drupal/drupal/.htaccess?revision=1.104
As Palantir wrote this is done using mod_rewrite and .htaccess. To get the correct rewrite conditions into your .htaccess you might want to take a look at a Mod Rewrite Generator (e.g. http://www.generateit.net/mod-rewrite/). Makes it a lot easier.
