How can substr be used dynamically to extract text after a specific string in PHP?

To extract text after a specific string in PHP, you can use the substr function along with strpos to find the position of the specific string. By using substr with the position of the specific string, you can extract the text after that point dynamically.

$string = "This is a sample string to extract text after specific string";
$specificString = "after";
$position = strpos($string, $specificString) + strlen($specificString);
$result = substr($string, $position);

echo $result;
