What are some potential pitfalls when working with multidimensional arrays in PHP, as discussed in the forum thread?

One potential pitfall when working with multidimensional arrays in PHP is accidentally overwriting values when trying to access or modify nested elements. To avoid this, it's important to use the correct array keys when accessing or updating values within the multidimensional array. 

// Example of accessing a nested value in a multidimensional array
$multiArray = [
    'key1' => [
        'key2' => 'value'
    ]
];

// Correct way to access the nested value
echo $multiArray['key1']['key2']; // Output: value
