Hellihello

auch wenns gleich Haue gibt hierfür:

  
  
<?php  
// testarray  
$myArray["a"] = "va";  
$myArray["b"] = "vb";  
$myArray["c"] = "vc";  
$myArray["aa"] = "vaa";  
$myArray["bb"] = "vbb";  
$myArray["cc"] = "vcc";  
  
// get Iterator  
$myArrayIterator = new ArrayIterator($myArray);  
  
// will be numeric key of current entry for orientation  
$seekKey = 0;  
  
foreach ($myArrayIterator as $key => $value) {  
 // finish if end is reached  
 if ($myArrayIterator->count() <= $seekKey +1) {  
  return;  
 }  
  
 // there must be an "a" in the key-name  
 if (strpos($key,"a") !==  false) {  
  
  // get value of next entriy using numeric key of actual position  
  $myArrayIterator->seek($seekKey + 1);  
  
  // output for test purpose  
  echo "next value: ";  
  echo $myArrayIterator->current();  
  echo "\n";  
  
  // go back to where we came from (thats the seekKey for too  
  $myArrayIterator->seek($seekKey);  
 }  
  
 // next numeric key for or  
 $seekKey++;  
}  
?>  

Dank und Gruß,
