Try something like this, you can deal with the linewraps ;)

<?

$haystackText = "Oh yeah, this is The text before, during, and The text
after";

$firstString = "The text before";

$secondString = "The text after";

$positionFirstString = strpos($haystackText, $firstString);
print("<p>First Position = $positionFirstString</p>");

$positionSecondString = strpos($haystackText, $secondString);
print("<p>Second Position = $positionSecondString</p>");


if ( $positionFirstString < $positionSecondString ) {
  $firstLength = strlen($firstString);
  $diffBetweenStringPositions = $positionSecondString -
$positionFirstString - $firstLength;
  $resultText =
substr($haystackText,$positionFirstString+$firstLength,$diffBetweenStringPositions);
} else {
  $secondLength = strlen($secondString);
  $diffBetweenStringPositions = $positionFirstString -
$positionSecondString - $secondLength;
  $resultText =
substr($haystackText,$positionSecondString+$secondLength,$diffBetweenStringPositions);

print("<p>$haystackText<br>$resultText</p>");
