PHP - Creating an XML file from an Object - php

I have a simple method inside a class that returns an Address based on a id.
For example:
$address = Address::get_by_id($id);
I'm calling the method based on a GET value. The function loads some data from the database and creates an XML file and then makes a map.
$map = new Map();
$map->create_address_xml($address);
Everything works as I expect when the URL is : /page?id=123
The problem I have is when I introduce a rewritten url.
For example
^pretty-url/([0-9]+)$ /page?id=$1 [L]
When the url is rewritten and I pass the $address object to $map->create_address_xml, it doesn't work.
I get no errors, so I'm stumped. Any suggestions?
PS. My first question on here (after much searching!) Please let me know if you need any more detail.

You can put Address fields in a json and Then convert it in XML.

Azure Functions with PHP

I'm trying out Azure Functions using PHP.
Getting the request information is not working for me.
I've not been able to find any documentation at all with the information of how to use Azure Functions with PHP code.
According to the only couple of examples, it seems that in order to retrieve the input information you need to first get the content of the req variable (or whatever name you assign in the function configuration).
That has the path of the file containing the request information (in theory).
$input_path = getenv('req');
So far, if I check the content of it, I get something like this:
D:\local\Temp\Functions\Binding\e2b6e195-02f7-481b-a279-eef6f82bc7b4\req
If I check if the file exists it says true, but the file size is 0.
Do anyone knows what to do here? Anyone with an example? Does anyone know where the documentation is?
Thanks
Ok, unfortunately there's pretty limited documentation out there for php as you have discovered.
At present, looking at the code might be the best doc. Here is the InitializeHttpRequestEnvironmentVariables function that adds request metadata to the environment for the script languages (node, powershell, php, python).
Important environment variables are:
REQ_ORIGINAL_URL
REQ_METHOD
REQ_QUERY
REQ_QUERY_<queryname>
REQ_HEADERS_<headername>
REQ_PARAMS_<paramname>
I'm assuming you've made a GET request, in which case there is no content (req is an empty file), but you will see that these other environment variables contain request data. If you were to make a POST request with a body then req would have data.
here is a full example parsing a GET request in PHP with an Azure Function :)
https://www.lieben.nu/liebensraum/2017/08/parsing-a-get-request-in-php-with-an-azure-function/
snippet from source:
<?php
//retrieve original GET string
$getReqString = getenv('REQ_QUERY');
//remove the ? for the parse_str function
$getReqString = substr($getReqString,1,strlen($getReqString));
//convert the GET string to an array
$parsedRequest = array();
parse_str($getReqString,$parsedRequest);
//show contents of the new array
print_r($parsedRequest);
//show the value of a GET variable
echo $parsedRequest["code"];
?>

Posting Data to REST API using JSON and PHP

I've been looking around at similar topics on REST APIs but I am still having some confusion in my project, mostly with the PHP side of things.
USPS provides a REST API with functions that can be called via URL like this: https://epfws.usps.gov/ws/resources/epf/login
To make any call successfully, I have been told that a JSON object must be created and passed as a "POST parameter" with the expected values.
This is the JSON object that needs to be passed in this case:
obj=
{
"login":"loginExample",
"pword":"passwordExample"
}
I have also been given a PHP class that is supposed to manage these calls. This is the login function:
public function login ()
{
// Set up the parameters for a login attempt
$jsonData = array(
'login' => $this->loginUser,
'pword' => $this->loginPass,
);
// Make a login request
$jsonResponse = $this->pullResource
('/epf/login', 'POST', $jsonData);
return $jsonResponse;
}
So I have a few questions regarding this:
The document they sent says
"To make the request calls, a JSON object will need to be created and passed as a POST form parameter obj={jsonObject} for security reasons using content-type “application/x-www-form-urlencoded”."
I know that the login function contains the correct input values that USPS' REST API is wanting, but I'm not sure how to pass them as "obj", or how to apply the "content-type".
I have a "constant" defined at the top of my PHP script that looks like this:
const EPF_BASE_URL = 'https://epfws.usps.gov/ws/resources';
And I noticed in the actual functions that this part of the link is left out and they simply reference '/epf/login' as you can see above. Since "$this" contains lots of different values I'm wondering how it supposedly finds EPF_BASE_URL as needed. Is it similar to how 'using' directives work in C#?
What is the easiest way to call this function and display the result? This is my biggest question. Would I use a separate PHP class with an HTML form? I understand the concept of what it should do but I'm completely lost setting up a development environment for it.
I've been trying all of this with MAMP but would love to know if I'm on the right track or not.
That really depends on their API. Hopefully you get a string back that can be decoded to a JSON object (http://au.php.net/manual/en/function.json-decode.php). Some API might give a simple string that says 'SUCCESS' or 'FAIL'. You've got the code, so take a look at what $this->pullResponse() gives you.
If you've been given a PHP class that is supposed to support the API (hopefully from USPS), then it should already take care of putting the data in the form content, and ensuring is it submitted with the appropriate content-type.
A PHP const is more like a C# static string. It is very likely that the library will use the constant to create the end URL (i.e. EPF_BASE_URL . $resource). If you needed to run against a sand box environment, you could change that constant without having to change all the other code.
That's a very big question, because it depends on how you are programming your application. Procedural, MVC, existing frameworks, etc.
At the very least, you would set the loginUser and loginPass on the instantiated object, and call the login method`. You could then inspect the results, assuming the result is a JSON object, or use your favourite debugging method to see the contents.
I'm having a guess as the USPS API class name.
$uspsApi = new UspsApi();
$uspsApi->loginUser = 'username';
$uspsApi->loginPass = 'password';
$result = $uspsApi->login();
echo print_r($result, true);

How can I get array from GET request?

I have a trouble:
I have url of view:
?materials=1&materials=2&materials=3&materials=4&materials=5&materials=6
How can I get it in array throw Yii mechanism?
Yii::app()->request->getParam('materials')
Not working
$_GET['materials']
Too not working
Url is static and can not change
This URL was created https://github.com/Mikhus/jsurl plugin
PHP automatically parses parameter as an array, if it ends by []. (i.e. ?materials[]=1&materials[]=2&materials[]=3&materials[]=4&materials[]=5&materials[]=6) Otherwise you can parse query string manually to solve your issue. Look at this

Using multiple nested _GET variables in a single URL

Setup:
Script that generates word images from multiple letter images
(autotext.php)
URL is formatted:
www.whatever.com/autotext.php?text=hello%20world
Script that alters images server-side to run filters or generate
smaller sizes (thumbnail.php)
URL is formatted:
www.whatever.com/thumbnail.php?src=whatever.png&h=XXX&w=XXX
Use-case:
I want to generate a smaller version of the autotext server-side. So my call would look something like:
www.whatever.com/thumbnail.php?src=autotext.php?text=hello%20world&h=XXX&w=XXX
As you can see, I would like to treat a URL with _GET variables as a variable itself. No amount of playing with URI encoding has helped make this work.
I have access to the PHP for both scripts, and can make some simple alterations if that's the only solution. Any help or advice would be appreciated. I would not even rule out a Javascript frontend solution, though my preference is to utilize the two scripts I already have implemented.
You should be able to do this by urlencoding all the $_GET params into a variable then assigning that variable to another, like this (untested):
// Url generation
$url = www.whatever.com/thumbnail.php?src=(urlencode(http_build_query($_GET)));
Then you should be able to retrieve on other side:
$src = urldecode(explode('&', $_GET['src']));
I've seen this exact behavior when trapping where to redirect a user, after an action occurs.
---- Update ----
Your "use case" url was correct:
www.whatever.com/thumbnail.php?src=autotext.php?text=hello%20world&h=XXX&w=XXX
.... except that you CANNOT have more than one ? within a "valid" url. So if you convert the 2nd ? to a &, you should then be able to access $_GET['text'] from the autotext.php script, then you can urldecode it to get the contents.

translate from ASP to PHP

I am being forced to work with a database company that only support ASP.NET, despite my employers being well aware that I only code in PHP and the project doesn't have the time to learn the new syntax.
Documentation is scant, and meaning in thin on the ground. Can someone help translate what is happening in this script, so that I can think about doing it in PHP
<%
QES.ContentServer cs = new QES.ContentServer();
string state = "";
state = Request.Url.AbsoluteUri.ToString();
Response.Write(cs.GetXhtml(state));
%>
QES.ContentServer cs = new QES.ContentServer();
the code instantiates the class method ContentServer()
string state = "";
Explicit the type var state as string
state = Request.Url.AbsoluteUri.ToString();
here you get the REQUEST URI (as in php) the path and convert it to one line string and put in the before mentioned string statte var
Response.Write(cs.GetXhtml(state));
and here return the message without refresh the page (ajax).
The Request object wraps a bunch of information regarding the request from the client i.e. Browser capabilities, form or querystring parameters, cookies etc. In this case it is being used to retrieve the absolute URI using Request.Url.AbsoluteUri.ToString(). This will be the full request path including domain, path, querystring values.
The Response object wraps the response stream sent from the server back to the client. In this case it is being used to write the return of the cs.GetXhtml(state) call to the client as part of the body of the response.
QES.ContentServer appears to be a third party class and is not part of the standard .NET framework so you would have to get access to the specific API documention to find out what is for and what the GetXhtml method does exactly.
So, in a nutshell, this script is taking the full URI of the request from the client and returning the output from the GetXhtml back in the response.
It would look like this in PHP:
<?php
$cs = new QES_ContentServer(); //Not a real php class, but doesn't look like a native ASP.NET class either, still, it's a class instantiation, little Google shows it's a class for Qwam E-Content Server.
$state = ""; //Superfluous in PHP, don't need to define variables before use except in certain logic related circumstances, of course, the ASP.NET could have been done in one line like "string state = Request.Url.AbsoluteUri.ToString();"
$state = $_SERVER['REQUEST_URI']; //REQUEST_URI actually isn't the best, but it's pretty close. Request.Url.AbsoluteUri is the absolute uri used to call the page. REQUEST_URI would return something like /index.php while Request.Url.AbsoluteUri would give http://www.domain.com/index.php
//$state = $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']; or something similar might be better in this case given the above
echo $cs->GetXhtml($state); //GetXhtml would be a method of QES.ContentServer, Response.Write is like echo or print.
?>
