What are the potential pitfalls of using YAML files in PHP for data storage?

One potential pitfall of using YAML files in PHP for data storage is the risk of exposing sensitive information if the files are not properly secured. To mitigate this risk, it is important to store YAML files outside of the web root directory and restrict access to them using appropriate file permissions. 

// Example code to store YAML file outside of web root directory
$yamlData = ['key' => 'value'];

$yamlFile = '/path/to/secure/directory/data.yaml';
file_put_contents($yamlFile, yaml_emit($yamlData));
