How can regular expressions be effectively used to convert C-Array syntax to PHP-Array syntax, and what are the performance implications of using different regex functions in PHP?

Regular expressions can be effectively used to convert C-Array syntax to PHP-Array syntax by matching the elements of the C-Array and then reconstructing them into a PHP-Array format. This can be achieved by using regex functions in PHP to search for patterns that represent C-Array elements and then replacing them with PHP-Array syntax. The performance implications of using different regex functions in PHP depend on the complexity of the regex pattern and the size of the input data. 

// Example code to convert C-Array syntax to PHP-Array syntax using regex

$cArray = "{1, 2, 3, 4, 5}";
$phpArray = preg_replace('/{(\d+(,\s*\d+)*)}/', '[$1]', $cArray);

echo $phpArray; // Output: [1, 2, 3, 4, 5]
