I have bellow URL and storing in one variable which is $currentURL.
$currentURL = http://localhost/example/villa-search/page/2/?features=Beachfront%2CCook%20Services%2CGarden%2CPrivate%20Pool%2CSea%20View
Now I want to break URL in to section and store in two different variables
First Part is:
http://localhost/example/villa-search
second Part is:
/page/2/?features=Beachfront%2CCook%20Services%2CGarden%2CPrivate%20Pool%2CSea%20View
How to make this possible?
You could use PHP's parse_url() and get components from it and re-construct your desired format from it.
And then use explode() the query part obtained from parse_url().

I have a pagination-instance where I want to append all query parameter from the request to the next_page_url attribute.
I have query parameter with a value like &name=chris but I also have single parameter without a value like &xyz.
However, when I append all query parameters to the pagination instance, like so:
$query->simplePaginate(50)->appends($request->all());
only parameters with a value are getting appended.
How can I append all parameters to the next_page_url?
Update
I want to append query parameters to get the next chunk of requested data.
If I don't, it always gives back "next_page_url":"http://vue.dev/contacts?page=2". What I want is "next_page_url":"http://vue.dev/contacts?name&page=2"
Take URL http://vue.dev/contacts?page=2&name for example. Although perfectly valid, it's still quite ambiguous. Do we mean to include name? Do we mean to exclude name?
So I'd suggest you to use this URL instead http://vue.dev/contacts?page=2&select=name. If you decide to select more stuff you can just do http://vue.dev/contacts?page=2&select=name,age,gender.
Later in your code just use explode to use the value as an array:
$attributes = explode(',', $request->select);

Even though Fahmis solution is possible as well, I end up using the approach from this so-question. This has the advantage that php reads the parameter as an array automatically. My url end up looking like this:
http://vue.dev/contacts?page=2&select[]=xyz&select[]=abc
I'm trying to put a script together for a client that needs to be able to accept a web address in a query string without it first being urlencoded. An example would be like this:
http://foo.com/script.php?url=www.amazon.co.uk/ESET-Smart-Security-User-Year/dp/B005NPFOBM/ref=sr_1_1?s=software&ie=UTF8&qid=1341685530&sr=1-1
However, when I echo out the contents of $_GET['url'] it gives me the following:
www.amazon.co.uk/ESET-Smart-Security-User-Year/dp/B005NPFOBM/ref=sr_1_1?s=software
So basically it seems to choke on the first ampersand - i'm guessing because it thinks that its another variable.
Aside form urlencoding, are there any tricks to getting this working? I could probably POST it from a form, but this defeats the idea of the script.
For this specific use case, you should use $_SERVER['QUERY_STRING'] instead. This will give you the full query string in one go, you can then split it yourself.
In your example, PHP is assuming that the & is the delimiter for the next GET variable.
you could ask the query parameters, and add them to the URL you received. List the remaining parameters in $_GET in the proper order, and add them add the end of $_GET['url'].
$_GET['url']
+ '&ie=' + $_GET['ie']
+ '&qid=' + $_GET['qid']
+ '&sr=' + $_GET['sr']
Be careful that you might get an extra parameter url someday.
http://foo.com/script.php?url=www.amazon.co.uk/ESET-Smart-Security-User-Year/dp/B005NPFOBM/ref=sr_1_1?s=software&ie=UTF8&qid=1341685530&sr=1-1&url=http://someAmazoneStuff
With this Symfony page, I am passing $_GET parameters in the URI like this:
http://www.mysite.com/article?page=4&sort=1
Once in my layout, there are certain links in the page that need to have the same query string in them.
Anyways, using Symfony's url_for() command I'm making URLs like so:
$url = url_for('article/index?.http_build_query($_GET));
That way it makes a new url using the $_GET variables. For some of the links I'm changing the $_GET values ahead of time, like $_GET['sort']=0; before generating the url. That's why I'm using this method.
Anyways, when I look at the generated URL, it now looks like this:
http://www.mysite.com/article?page=4&%3Bsort=1
The &%3B is the encoded form of & which is just an & character.
So the problem is that when I check for my $_GET parameters in my controller now, there is no longer a sort parameter that is passed. It's now called &%3Bsort... It's causing all sorts of issues.
Two questions:
How do I avoid this problem? Can I decode the $_GET parameter key values in my controller or something?
Why is symfony encoding a & character in the first place? It's a perfectly acceptable URI character. Heck, even the encoded value, &%3B contains a & !!!
I believe, it is because of output escaping is ON in your application. As a result, $_GET array is wrapped inside sfOutputEscaperArrayDecorator class. You can get a raw value using this: $_GET->getRawValue().
$url = url_for('article/index?.http_build_query($_GET->getRawValue()))
Or you can decode the result query using sfOutputEscaper::unescape
$url = url_for('article/index?.sfOutputEscaper::unescape(http_build_query($_GET)));
Hope this will be useful.
Best if you use Symfony's own method for getting the request parameters. For example, in templates, use:
$sf_request->getParameter('some_param');
If you must use $_GET, maybe try:
((( $sf_data->getRaw('_GET') )))
... to get past the output escaping. Not totally sure if that'll work as is.
This might be a basic question and I've been searching for a safe and clean way to do this. Im passing a normal string which CAN include special characters (like $ ^ % etc). How can I do this in the url? For example I have a variable called $text which In addto.php from $_GET. How do I then transfer this to more.php?
'more.php?varname='.urlencode($_GET['text']);
urlencode sounds like what you want.
(from the docs)
This function is convenient when encoding a string to be used in a query part of a URL, as a convenient way to pass variables to the next page.
You can pass data through an URL, it should be in the form of key/value pairs, but you shouldn't use it to pass too much data because an URL has a limit. You also should not pass sensitive information.
A key/value pair is something like this:
key=value
If you have more then one pair, you need to separate them using the & char. Here is an example:
myScript.php?color1=blue&color2=red
The string after ? is called the Query String. With PHP you can easily access those key/value pairs using the super-global $_GET. So, in myScript.php you do:
$a = $_GET['color1'];
$b = $_GET['color2'];
Now, if you are going to create a dynamic query string, you should use urlencode() at least, so any special characters will be translated to maintain a proper URL format.
Please read the following:
http://php.net/urlencode
http://php.net/manual/en/function.http-build-query.php
Regular expressions have never been one of my strong points, and this one has me stumped. As part of a project, I want to develop an SEO link class in PHP. Handling the mod_rewrite through Apache is fairly straightforward for me, and that works great.
However, I'd like to create a function which is able to generate the SEO link based on a dynamic URL I pass in as the first (and only) parameter to the function.
For example, this would be the function call in PHP:
Blog Post Title
The function CreateLink would then analyse the string passed in, and output something like this:
blog/blog-post-title
The URL stub of the blog post is stored in the Database already. I think the best way to achieve this is to analyse the dynamic URL string passed in, and generate an associative array to be analysed. My question is, what would the Regular Expression be to take the URL and produce the following associative array in PHP?
link_pieces['page_type'] = 'blog/post';
link_pieces['post'] = 123;
link_pieces['category'] = 5;
Where page_type is the base directory and request page without extension, and the other array values are the request vars?
You can just use parse_url and parse_str, no need for regexes.
Use parse_url to break the URL into parts:
This function parses a URL and returns an associative array containing any of the various components of the URL that are present.
Then use parse_str to break down the querystring part of the URL.
