Are there any potential pitfalls when using eregi_replace in PHP?

Using eregi_replace in PHP is deprecated as of PHP 5.3.0 and removed in PHP 7.0.0. This function is case-insensitive, which can lead to unexpected results and security vulnerabilities. It is recommended to use the preg_replace function with the 'i' modifier for case-insensitive replacements. 

// Replace eregi_replace with preg_replace for case-insensitive replacements
$pattern = '/pattern/i';
$replacement = 'replacement';
$string = 'example string';
$result = preg_replace($pattern, $replacement, $string);
echo $result;
