What is the potential issue with dynamically changing variable names in PHP?

Dynamically changing variable names in PHP can make the code harder to read and maintain. It can also introduce potential bugs and security vulnerabilities if not handled carefully. To solve this issue, it's recommended to use arrays or objects to store dynamic data instead of creating variables with dynamic names. 

// Using an array to store dynamic data instead of creating variables with dynamic names
$data = array();
$data['dynamic_var1'] = 'value1';
$data['dynamic_var2'] = 'value2';

echo $data['dynamic_var1']; // Output: value1
echo $data['dynamic_var2']; // Output: value2
