What are the potential pitfalls of using arrays for storing BBCode replacements in PHP?

Using arrays for storing BBCode replacements in PHP can lead to potential pitfalls such as limited flexibility in adding or modifying replacements, difficulty in managing a large number of replacements, and potential performance issues when searching through the array for replacements. To solve this issue, consider using a more structured data format such as a multidimensional array or a database table to store and manage BBCode replacements.

// Example of using a multidimensional array for storing BBCode replacements
$bbcodeReplacements = [
    'b' => [
        'open' => '<strong>',
        'close' => '</strong>'
    ],
    'i' => [
        'open' => '<em>',
        'close' => '</em>'
    ],
    // Add more BBCode replacements as needed
];

// Example of accessing a BBCode replacement
$bbcode = 'b';
echo $bbcodeReplacements[$bbcode]['open']; // Output: <strong>
