How can the issue of adding a prefix to a variable name be addressed in PHP?

When adding a prefix to a variable name in PHP, it can be cumbersome and error-prone to manually update each occurrence of the variable throughout the code. To address this issue, you can use PHP's variable variables feature to dynamically create variable names with the desired prefix. 

$originalVariable = "Hello";
$prefix = "prefix_";

// Create a new variable with the prefix
${$prefix . 'originalVariable'} = $originalVariable;

// Now you can use the variable with the prefix
echo $prefix_originalVariable; // Output: Hello
