Are there any potential issues when using variables as node identifiers in PHP?

When using variables as node identifiers in PHP, there may be potential issues with readability and potential conflicts if the variables are not properly sanitized. To solve this issue, it is recommended to use a consistent naming convention for variables and ensure that they do not conflict with any existing node identifiers. 

// Example of using a consistent naming convention for variables as node identifiers
$node_id = 1;
$node_title = "Example Node";

// Use the variables in your code
echo "<div id='node_$node_id'>$node_title</div>";
