Generate the following XML string
encoding="utf-8"?>

                                                                                                                     ;/content> ; 2009-10-11 title2
                                                                                                                  


Method I. [Generate string directly]

Use pure PHP code to generate a string and write the string into a file with XML as suffix. This is the most primitive way to generate XML, but it works!



Copy code

The code is as follows:


$data_array = array(
array(
'title' => 'title1', 'content' => 'content1',
'pubdate' => '2009-10-11',
),
array(
'title' => 'title2', 'content' => 'content2', 'pubdate' => '2009-11-11', ));
$title_size = 1;
$xml = "n";
$xml .= "< ;article>n";
foreach ($data_array as $data) {
$xml .= create_item($data['title'], $title_size, $data['content'], $data[' pubdate']);
}
$xml .= "n";
echo $xml;
// Create XML single item
function create_item($title_data, $ title_size, $content_data, $pubdate_data)
{
$item = "n";
$item .= "" . $title_data . "n";
$item .= "" . $content_data . "n";
$item .= " n";
$item .= "
n";
return $item;
}
?>



Method 2: [DomDocument]

Use DomDocument to generate XML files, create nodes using the createElement method, create text content using the createTextNode method, add child nodes using the appendChild method, and create attributes Use the createAttribute method



to copy the code

The code is as follows:

$data_array = array(
array(
'title' => 'title1',
'content' => 'content1',
       'pubdate' => '2009-10-11',
  ),
   array(
   'title' => 'title2',
   'content' => 'content2 ',
'pubdate' => '2009-11-11',
)
);
// Attribute array
$attribute_array = array(
'title' = > array(
'size' => 1
)
);
// Create an XML document and set the XML version and encoding. .
$dom=new DomDocument('1.0', 'utf-8');
// Create root node
$article = $dom->createElement('article');
$ dom->appendchild($article);
foreach ($data_array as $data) {
$item = $dom->createElement('item');
$article->appendchild( $item);
create_item($dom, $item, $data, $attribute_array);
}
echo $dom->saveXML();
function create_item($dom, $item , $data, $attribute) {
if (is_array($data)) {
foreach ($data as $key => $val) {
$$key = $dom->createElement ($key); ; ($attribute[$key] as $akey => $row) {
                                                                                     $$key- >appendchild($$akey);
                                                                                       gt;appendChild($aval);
                                                                                                                                                             🎜> Method 3: [XMLWriter]

Use the XMLWriter class to create XML files. This method is valid after PHP 5.1.2. In addition, it can output multiple encodings of XML, but the input can only be utf-8



Copy code

The code is as follows:

$data_array = array(
array(
'title' => 'title1',
'content' => 'content1',
       'pubdate' => '2009-10-11',
  ),
   array(
   'title' => 'title2',
   'content' => 'content2 ',
'pubdate' => '2009-11-11',
)
);
// Attribute array
$attribute_array = array(
'title' = > array(
'size' => 1
)
);
$xml = new XMLWriter();
$xml->openUri("php://output ");
// The output method can also be set to an xml file address and directly output into a file
$xml->setIndentString(' ');
$xml->setIndent(true );
$xml->startDocument('1.0', 'utf-8');
// Start creating file
// Root node
$xml->startElement(' article');
foreach ($data_array as $data) {
$xml->startElement('item');
if (is_array($data)) {
foreach ($data as $key => $row) {
                                                                                                  using   with  --                                                            ​​​($akey, $aval);
                                                                                                                                  }
}
$xml->endElement(); // item
}
$xml->endElement(); // article
$xml->endDocument();
$xml ->flush();
?>



Method 4: [SimpleXML]

Create XML document using SimpleXML



Copy code

The code is as follows:
$data_array = array(
array( 'title' => 'title1', 'content' => 'content1', 'pubdate' => '2009-10-11', ),
array(
'title' => 'title2',
'content' => 'content2',
'pubdate' => '2009-11-11',
)
);
/ / Attribute array
$attribute_array = array(
'title' => array(
'size' => 1
)
);
$string =


XML;
$ xml = simplexml_load_string($string);
foreach ($data_array as $data) {
$item = $xml->addChild('item');
if (is_array($data)) {
foreach ($data as $key => $row) {
$node = $item->addChild($key, $row);
if (isset($attribute_array[$key] ) && is_array($attribute_array[$key]))
                                                                                           $node ->addAttribute($akey, $aval);
}
}
}
}
}
echo $xml->asXML();
?> ;

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
