How to read XML file in PHP

SimpleXML is a PHP extension introduced in PHP5, allowing users to easily process XML data in PHP. SimpleXML can convert any XML data into an object that can be easily processed using ordinary attribute selectors and array iterators.

Note: The How to read XML file in PHP-simplexml extension must be installed on the system to use it.

Let’s look at specific examples

The code is as follows

<?xml version="1.0"?>
<company>
 <employee>
 <firstname>Tom</firstname>
 <lastname>Cruise</lastname>
 <designation>MD</designation>
 <salary>500000</salary>
 </employee>
 <employee>
 <firstname>Tyler</firstname>
 <lastname>Horne</lastname>
 <designation>CEO</designation>
 <salary>250000</salary>
 </employee>
</company>

Read specific XML elements

Use the simplexml_load_file function in PHP The program loads an external XML file and creates an object. Afterwards, any element in the XML can be accessed through this object as shown below.

<?How to read XML file in PHP
$xmldata = simplexml_load_file("employees.xml") or die("Failed to load");
echo $xmldata->employee[0]->firstname . "<\n>";
echo $xmldata->employee[1]->firstname; 
?>

The output is:

Tom
Tyler

Reading XML elements in a loop

In this example, we use the foreach method to iterate over the entire XML file and read elements from XML. Foreach loops through all children of an object.

<?How to read XML file in PHP
$xmldata = implexml_load_file("employees.xml") or die("Failed to load");
foreach($xmldata->children() as $empl) {         
 echo $empl->firstname . ", ";     
 echo $empl->lastname . ", ";     
 echo $empl->designation . ", ";        
 echo $empl->salary . "<\n>"; 
} 
?>

The output results are as follows

Tom, Cruise, MD, 500000
Tyler, Horne, CEO, 250000
