How can a PHP developer ensure that IDs are unique and do not cause conflicts when using preg_replace in their code?

To ensure that IDs are unique and do not cause conflicts when using preg_replace in PHP, developers can generate a unique ID using functions like uniqid() and append it to the ID being replaced. This way, each ID will be unique and prevent conflicts. 

// Example code snippet to ensure unique IDs when using preg_replace
$original_string = "This is a test string with ID: %ID%";
$unique_id = uniqid();
$modified_string = preg_replace('/%ID%/', $unique_id, $original_string);

echo $modified_string;
