What are the best practices for handling XML streams in PHP when received through HTTP PUSH?

When receiving XML streams through HTTP PUSH in PHP, it is important to handle the data efficiently to prevent memory leaks and ensure proper parsing. One best practice is to process the XML data as a stream rather than loading the entire document into memory at once. This can be achieved by using PHP's XMLReader class, which allows for sequential reading of XML data without loading the entire document. 

// Initialize XMLReader object
$xmlReader = new XMLReader();

// Open a stream to receive the XML data
$stream = fopen('php://input', 'r');
$xmlReader->open($stream);

// Loop through the XML data stream
while ($xmlReader->read()) {
    // Process each node as needed
    switch ($xmlReader->nodeType) {
        case XMLReader::ELEMENT:
            // Handle XML element
            break;
        case XMLReader::TEXT:
            // Handle text data
            break;
        // Add cases for other node types as needed
    }
}

// Close the XMLReader and stream
$xmlReader->close();
fclose($stream);
