$test = array('MAMA' => 'papa',
   'SISTER' => 'brother');

I want this array to be used for replaceing inside a string, the case shouldn't matter but
it should adopt the case of the source (so replace Mama  by Papa and SiStEr by BrOtHer).
I'm not sure how to start without using a loop which would make the script slow...

<?

$test = array('MAMA' => 'papa', 'SISTER' => 'brother', 'SIBLING' =>
'ancestor','GRANDMOTHER'=>'Aunt');

$string = "Mama loves Sister like SibLing loves Grandmother" ;

foreach ($test as $key => $value) {
 if (eregi($key, $string, $match)) {
  $repl = "" ;
  for ($i = 0; $i < strlen($match[0]); $i++) {
   $char = $match[0][$i] ;
   if ($match[0][$i] == strtolower($char)) {
    $repl .= strtolower($test[$key][$i]) ;
   } else if ($match[0][$i] == strtoupper($char)) {
    $repl .= strtoupper($test[$key][$i]) ;
   } else {
    $repl .= $test[$key][$i] ;
   }
  }
  $repl = strlen($test[$key]) > strlen($repl) ?
$repl.substr($test[$key],strlen($repl)) : $repl ;
  $string = str_replace($match[0],$repl, $string) ;
 }

?>
