Is it a good practice to nest substr() with strpos() and strrpos() in PHP code?

Nesting substr() with strpos() and strrpos() in PHP code can make the code harder to read and maintain. It is generally recommended to break down the logic into separate steps for clarity and easier debugging. By using separate variables for the positions found with strpos() and strrpos(), the code becomes more organized and understandable.

$string = "Hello, World!";
$startPos = strpos($string, ",") + 2; // Find the position after the comma
$endPos = strrpos($string, "!"); // Find the position of the exclamation mark
$result = substr($string, $startPos, $endPos - $startPos); // Extract the substring between the comma and exclamation mark
echo $result; // Output: World
