Are there any best practices or recommended approaches for efficiently extracting substrings from strings in PHP?

When extracting substrings from strings in PHP, a common approach is to use the `substr()` function. This function allows you to specify the starting position and length of the substring you want to extract. Additionally, you can use functions like `strpos()` to find the position of a specific substring within a larger string.

// Extract a substring starting at position 5 with a length of 10 characters
$originalString = "Hello, World!";
$substring = substr($originalString, 5, 10);
echo $substring;

// Find the position of a specific substring within a larger string
$originalString = "Hello, World!";
$position = strpos($originalString, "World");
echo $position;
