In what scenarios would it be more efficient to use sscanf() or preg_match() instead of preg_split() for string manipulation in PHP?

When dealing with string manipulation in PHP, it may be more efficient to use sscanf() or preg_match() instead of preg_split() in scenarios where you only need to extract specific parts of a string rather than splitting it into multiple parts. These functions allow you to target and extract specific patterns or values from a string without the overhead of splitting the entire string into an array.

// Example using sscanf()
$string = "Name: John Doe";
sscanf($string, "Name: %s", $name);
echo $name; // Output: John Doe

// Example using preg_match()
$string = "Age: 30";
preg_match("/Age: (\d+)/", $string, $matches);
$age = $matches[1];
echo $age; // Output: 30
