In the context of PHP development, what are some alternative approaches to cutting out a specific portion of a string besides using substring functions or regular expressions?

When needing to cut out a specific portion of a string in PHP without using substring functions or regular expressions, one alternative approach is to use the `explode` function to split the string into an array based on a delimiter and then manipulate the desired portion accordingly. Another approach is to use `strpos` function to find the position of the substring to be removed and then use `substr` function to extract the desired portions before and after it. 

// Using explode function
$string = "Hello World";
$parts = explode(" ", $string);
$desired_portion = $parts[1]; // "World"

// Using strpos and substr functions
$string = "Hello World";
$substring = "World";
$pos = strpos($string, $substring);
$before = substr($string, 0, $pos); // "Hello "
$after = substr($string, $pos + strlen($substring)); // ""
