What are the risks of using deprecated functions like ereg() in PHP scripts?

Using deprecated functions like ereg() in PHP scripts can lead to security vulnerabilities and compatibility issues as these functions are no longer maintained and may not work in newer PHP versions. To solve this issue, you should replace deprecated functions with their updated counterparts, such as preg_match() for pattern matching in PHP. 

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

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