<?php
$str='This is the new line!'."\n";
$file=dirname(__FILE__).'/Edit2.txt';
$contents=file($file);
foreach($contents as $id=>$line)
if(preg_match('/^something=(\r\n|\r|\n)$/',$line))
break;
$ar_end=array_splice($contents,$id+1);
$contents[]=$str;
$contents=array_merge($contents,$ar_end);
$fp=fopen($file,'w');
foreach($contents as $line)
fwrite($fp,$line,strlen($line));
fclose($fp);
?>

This will make sure that the the full line is matched, not just part of
it (in case you have "someting=" in another line as well). Not as
graceful as a simple:

preg_replace('/^(something=(\r\n|\r|\n))$/',"$1\n$str",$subject);

But I needed this exact functionality for something else. (I stripped
all the error-checking stuff to avoid confusion.)
