There are many functions for manipulating text. The two functions you'll want to use for your problem would be strpos and substr. Have a readup on those two functions and see if you can work it out.

Example code

$string = 'problem is an obstacle, impediment, difficulty or challenge, or any situation that invites resolution; the resolution of which is recognized as a solutionquestion raised for inquiry, consideration, or solution proposition in mathematics or physics stating something to be done';

$word = 'inquiry';
$word_pos = strpos($string, $word); // get the position of the word

$startPos = $word_pos - 20;     // 20 characters to the left of the word
$endPos   = strlen($word) + 40; // 20 characters to the right of the word

$new_string = substr($string, $startPos, $endPos);

echo "...$new_string...";
