Php create xml file from array

Array2xml is a PHP library that converts array to valid XML.

Usage (Ex.: RSS Last News)

Load the library and set custom configuration:

Start by creating a root element:

Now pass elements from DB query in cycle:

You can also set element attributes individually. The example below appends an attribute AttributeName to item node:

Or, if your node doesn’t have children, you can use this:

This will set both attributes and the content of channel node.

Alternatively, you can use setElementsAttrs() method:

Note that in this case all elements with specified names will have identical attribute names and values.

Finally, convert and print output data to screen

You can easily configure this lib to fit your specific use case using setters described below.

Sets XML version header.

Set XML Root Element Name

Set XML Root Element Attributes

Set Attributes of every XML Elements that matches the given names. Example argument: [‘elementName’ => [‘someAttr’ => ‘attrValue’]]

Marking given elements as CData ones

Marking given elements as raw ones

Set default prefix for numeric nodes

On/Off Skip numeric nodes

In some cases you might want to control the exact syntax of empty elements.

By default, nodes that are empty or equal to null are using self-closing syntax( ).

You can override this behavior using Array2xml::EMPTY_FULL to force using closing tag( ).

Available agruments are Array2xml::EMPTY_SELF_CLOSING or Array2xml::EMPTY_FULL

Remove numbers from element names.

This is a easy workaround to have identically named elements in your XML built from an array.

For example, let’s build an XML with 3 image nodes:

That’s it! Now we have a nasty XML with 3 identically named nodes in it.

Создание XML-документа на PHP

В нижеследующем примере идёт генерация XML-документа на PHP:

Всё самое основное, что Вы должны знать при создании XML-документов через PHP, находится в данном примере. Код я постарался хорошо прокомментировать, поэтому вопросов возникнуть не должно. Вы, обладая данными знаниями, уже можете создать практически любой XML-документ, используя стандарт DOM. А в следующей статье я Вам покажу, как парсить XML-документ через PHP.

I’ve been working with the Google Contacts API lately and needed to construct some XML as a part of that. PHP’s DOMDocument works really great for this, but it can get complicated fast as you need to create lots of variables for all of your elements, children, etc. It can make it quite hard to do dynamically.

An easier method would be to just convert an array into XML, the opposite of simplexml_load_string() if you will. So I wrote some code that does exactly that and I thought I’d share it incase anyone else would find it helpful. 🙂

Start by creating your array of data. I used a numeric array instead of an associative array because you can have duplicate elements in XML while you cannot have duplicate array keys.

An array such as that is easy to dynamically create based on your source data, it’s easy to read, and can be fairly easily manipulated.

name is the only required item of each array and it’s the tag name of the element. attributes is an array of attributes for the element and value is the value. Both of these are optional. Any children arrays are children elements and their structures should be the same.

Now here’s the code I wrote that converts the above array into some XML:

You first create a blank canvas by creating a new instance of the DOMDocument class and then you pass the class instance (needed for creating elements in the correct character set and such) and the data array to the generate_xml_element() function. This function will create the top level element and then recursively call itself on any child elements until it’s gone through the whole array.

Once it’s done, you’ll need to append the element to the DOM using the inherited appendChild() function. Then calling saveXML will give you the XML output. The above example data array will give you something like this (maybe or maybe not nicely formatted with whitespace depending on what mood DOMDocument is in):

And there you have it!

I tried your creating an XML file from a PHP array. I used your example and could not the XML tree, only the values. I am probably missing something. I have been using PHP for over a dozen years, however this is the first time I tried to turn a PHP array in an XML output. If I ask real nice you assist me?

I would like to take this sample array and turn it into a similar XML out as the example below.

With XML, I believe you need to have a single top level element to contain all of your data. Even if you don’t, my code requires one, so I made it “location”.

Now the dumb question of the day; How do I get it to display as an XML tree like yours? I feel like such a novice today.

Mine comes out as one long of only the values;

95610Citrus HeightsKMCCMcClellan Airfield7.306701182156538.667-121.4

If you’re echo ‘ing it, then your browser is probably trying to render it as HTML tags. Use var_dump() or view the source.

Thank you for everything. “View Source” does not seem to work. The var_dump($xml) does not give me that XML format.

Result from var_dump($xml:
string(223) ” 95610Citrus HeightsKMCCMcClellan Airfield7.306701182156538.667-121.4 “

If you wrap the output in htmlentities() you’ll get the response as XML.

add header( “content-type: application/xml; charset=ISO-8859-15” ); in your code

Hi, I need your help.

This way you can print:

?>
—————————————————-
However, only the html table is added to the database, data is not added into HTML table cells.

How do i generate a tree structure like a parent can have a child and that child can be a parent to another child

PHP XML Tutorial: Create, Parse, Read with Example

Updated August 27, 2021

What is XML?

XML is the acronym for Extensible Markup Language.

XML is used to structure, store and transport data from one system to another.

XML is similar to HTML.

It uses opening and closing tags.

Unlike HTML, XML allows users to define their own tags.

In this tutorial, you will learn-

What is DOM?

DOM is the acronym for Document Object Model.

It’s a cross platform and language neutral standard that defines how to access and manipulate data in;

DOM XML is used to access and manipulate XML documents. It views the XML document as a tree-structure.

XML Parsers

An XML parser is a program that translates the XML document into an XML Document Object Model (DOM) Object.

The XML DOM Object can then be manipulated using JavaScript, Python, and PHP etc.

The keyword CDATA which is the acronym for (Unparsed) Character Data is used to ignore special characters such as “ ” when parsing an XML document.

Why use XML?

XML Document example

Let’s suppose that you are developing an application that gets data from a web service in XML format.

Below is the sample of how the XML document looks like.

How to Read XML using PHP

Let’s now write the code that will read the employees XML document and display the results in a web browser. Index.php

Testing our application

Assuming you saved the file index.php in phptus/xml folder, browse to the URL http://localhost/phptuts/xml/index.php

How to Create an XML document using PHP

We will now look at how to create an XML document using PHP.

We will use the example above in the DOM tree diagram.

The following code uses the PHP built in class DOMDocument to create an XML document.
