What are the potential pitfalls of using dynamic variables in PHP, as discussed in the forum thread?

The potential pitfalls of using dynamic variables in PHP include security vulnerabilities such as injection attacks and difficulty in debugging code. To avoid these issues, it is recommended to use associative arrays instead of dynamic variables. 

// Instead of using dynamic variables like $var1, $var2, $var3
// Use an associative array to store and access values

$vars = array(
    'var1' => 'value1',
    'var2' => 'value2',
    'var3' => 'value3'
);

echo $vars['var1']; // Output: value1
