What are the recommended alternatives to using deprecated functions like eregi() in PHP scripts?

The eregi() function in PHP is deprecated and should not be used in scripts as it is no longer supported in newer versions of PHP. To replace eregi(), developers can use the preg_match() function with the 'i' modifier to perform case-insensitive regular expression matching. 

// Deprecated eregi() function
if (eregi("hello", $string)) {
    echo "Match found!";
}

// Recommended alternative using preg_match() with 'i' modifier
if (preg_match("/hello/i", $string)) {
    echo "Match found!";
}
