In what scenarios would using explode be a less optimal solution compared to preg_match and preg_match_all for data extraction in PHP?

When dealing with more complex data patterns or when needing to extract specific parts of a string using regular expressions, using explode may not be as optimal as preg_match and preg_match_all in PHP. These functions offer more flexibility in defining patterns and capturing specific data, making them more suitable for scenarios where data extraction requires more precision and control. 

// Using preg_match to extract a specific pattern from a string
$string = "Hello, my email is example@email.com";
$pattern = '/[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}/';
preg_match($pattern, $string, $matches);
$email = $matches[0];
echo $email;
