What are the potential challenges of passing multiple variables like $row[bezeichnung] in PHP and how can they be overcome?

Passing multiple variables like $row['bezeichnung'] in PHP can be challenging because it requires careful handling of the data to ensure that each variable is correctly passed and utilized. One way to overcome this challenge is by using an associative array to store and pass multiple variables efficiently.

// Example of passing multiple variables using an associative array
$row = array(
    'bezeichnung' => 'Variable 1',
    'variable2' => 'Variable 2',
    'variable3' => 'Variable 3'
);

// Accessing the variables from the associative array
echo $row['bezeichnung']; // Output: Variable 1
echo $row['variable2']; // Output: Variable 2
echo $row['variable3']; // Output: Variable 3
