PHP

$var="Duis posuere nunc sit amet sapien pharetra, at scelerisque risus fringilla. Aenean sed purus nec quam ullamcorper aliquam.";

printf("%s %s","String equals:",$var);

echo "<pre>"; 

echo "<p><b>Substring: substr(\$var,12,9): ' nunc sit'</b></p>";

echo "<p>".substr($var,12,9)."</p>";

echo "<p><b>Substring and Subpoition: substr(\$var,27,6).' => '.strpos(\$var,'sapien'): sapien => 27</b></p>";

echo "<p>".substr($var,27,6)." => ".strpos($var,"sapien")."</p>";

echo "</pre>";

echo "<p><b>explode string and list</b></p>";

$arr=explode(" ",$var);

foreach($arr as $val){

  echo "<p>".$val."</p>";

}  

echo "<p><b>explode string to array and implode back to string (just because)</b></p>";

echo "<pre>";

echo "<p>".implode(" ",explode(" ",$var))."</p>";

echo "</pre>";

  

//Result

String equals: Duis posuere nunc sit amet sapien pharetra, at scelerisque risus fringilla. Aenean sed purus nec quam ullamcorper aliquam.

Substring: substr($var,12,9): ' nunc sit'

nunc sit

Substring and Subpoition: substr($var,27,6).' => '.strpos($var,'sapien'): sapien => 27

sapien => 27

explode string and list
