In the context of PHP programming, what are the advantages and disadvantages of using loops versus built-in functions for tasks like extracting specific portions of a string?

When extracting specific portions of a string in PHP, using built-in functions like `substr()` or `explode()` can be more efficient and concise compared to using loops. Built-in functions are optimized for these specific tasks and can often achieve the desired result with fewer lines of code. However, using loops may provide more flexibility and customization options for complex string manipulation tasks. 

// Using built-in functions to extract specific portions of a string
$string = "Hello, World!";
$substring = substr($string, 7); // Extracts "World!" starting from index 7
echo $substring;
