How can PHP developers ensure that they are specifying the correct file path when loading external entities?

PHP developers can ensure they are specifying the correct file path when loading external entities by using absolute paths instead of relative paths. This helps avoid any ambiguity in the file location and ensures that the correct file is being loaded. 

$filePath = '/path/to/external/file.xml';
$doc = new DOMDocument();
$doc->load($filePath);
