What are the potential issues with using deprecated functions like ereg in PHP scripts?

Using deprecated functions like ereg in PHP scripts can lead to compatibility issues with newer versions of PHP, as these functions may be removed entirely. To solve this issue, you should replace deprecated functions with their updated counterparts. In the case of ereg, you can use the preg_match function as a modern alternative. 

// Deprecated ereg function
if (ereg('pattern', $string)) {
    // do something
}

// Updated preg_match function
if (preg_match('/pattern/', $string)) {
    // do something
}
