How can one efficiently check the size of an XML file in PHP to determine if it is causing performance issues?

Large XML files can cause performance issues in PHP due to increased memory usage and processing time. To efficiently check the size of an XML file, you can use the filesize() function to get the file size in bytes and compare it against a threshold value. If the file size exceeds the threshold, you can take appropriate actions such as optimizing the XML processing or implementing pagination. 

$file = 'example.xml';
$threshold = 10 * 1024 * 1024; // 10 MB threshold

$filesize = filesize($file);

if ($filesize > $threshold) {
    // File size exceeds threshold, take appropriate actions
    echo "XML file size is too large!";
} else {
    // File size is within threshold, continue processing
    echo "XML file size is acceptable.";
}
