Problem Looping an array

[mrbaseball34]

In working with Paypal's Adaptive Payments API, the response to
the CallPay() function returns an array with items names as such:

$resArray["error(0).errorId"]
$resArray["error(0).message"]
$resArray["error(0).domain"]
$resArray["error(0).severity"]
$resArray["error(0).category"]

There may be more than one error() value, so I also need
to check for error(1)... ,error(2)..., etc.

How can I do this in a loop? I thought about this but not sure
how to count how many error() items there are.

 for($i=0;$i<count(?????);$i++) {
   $ErrorCode = urldecode($resArray["error($i).errorId"]);
   $ErrorMsg = urldecode($resArray["error($i).message"]);
   $ErrorDomain = urldecode($resArray["error($i).domain"]);
   $ErrorSeverity = urldecode($resArray["error($i).severity"]);
   $ErrorCategory = urldecode($resArray["error($i).category"]);
 }
  echo "Preapproval API call failed. ";
  echo "Detailed Error Message: " . $ErrorMsg;
  echo "Error Code: " . $ErrorCode;
  echo "Error Severity: " . $ErrorSeverity;
  echo "Error Domain: " . $ErrorDomain;
  echo "Error Category: " . $ErrorCategory;

Could you combine a while loop with something like is_empty() or isset()?

I think dalecosp and I are both killing time tell we can go home 😉

I was typing this up while he replied, but I had the same line of thinking. I don't know if the errors are static or not, but you can edit it if they aren't.

$resArray["error(0).errorId"] = 'val';
$resArray["error(0).message"] = 'val';
$resArray["error(0).domain"] = 'val';
$resArray["error(0).severity"] = 'val';
$resArray["error(0).category"] = 'val';

$errors[] = 'errorId';
$errors[] = 'message';
$errors[] = 'domain';
$errors[] = 'severity';
$errors[] = 'category';

$resCopy = $resArray;

$i = 0;
while(!empty($resCopy)){

foreach($errors as $error_suffix){

	$index = "error(".$i.").".$error_suffix;

	if(key_exists($index, $resCopy)){
		echo $resCopy[$index];
		unset($resCopy[$index]);

	}

}
$i++;
}

Here's what I eventually came up with, thanks Res...

  $resArray["error(0).errorId"] = "errorId - 0";
  $resArray["error(0).message"] = "message - 0";
  $resArray["error(0).domain"] = "domain - 0";
  $resArray["error(0).severity"] = "severity - 0";
  $resArray["error(0).category"] = "category - 0";
  $resArray["error(1).errorId"] = "errorId - 1";
  $resArray["error(1).message"] = "message - 1";
  $resArray["error(1).domain"] = "domain - 1";
  $resArray["error(1).severity"] = "severity - 1";
  $resArray["error(1).category"] = "category - 1";
  $resArray["error(2).errorId"] = "errorId - 2";
  $resArray["error(2).message"] = "message - 2";
  $resArray["error(2).domain"] = "domain - 2";
  $resArray["error(2).severity"] = "severity - 2";
  $resArray["error(2).category"] = "category - 2";

  $errors[] = 'errorId';
  $errors[] = 'message';
  $errors[] = 'domain';
  $errors[] = 'severity';
  $errors[] = 'category';

  $resCopy = $resArray;
  for($i=0;$i<count($resArray);$i++) {
    foreach($errors as $error_suffix){
      $index = "error(".$i.").".$error_suffix;
      if(key_exists($index, $resArray)) {
        switch ($error_suffix) {
          case 'errorId':
            $ErrorCode     .= urldecode($resArray[$index]) . ' : ';
          break;
          case 'message':
            $ErrorMsg      .= urldecode($resArray[$index]) . ' : ';
          break;
          case 'domain':
            $ErrorDomain   .= urldecode($resArray[$index]) . ' : ';
          break;
          case 'severity':
            $ErrorSeverity .= urldecode($resArray[$index]) . ' : ';
          break;
          case 'category':
            $ErrorCategory .= urldecode($resArray[$index]) . ' : ';
          break;
        } // switch
      } // if
    }// foreach
  }  // for
  echo "Preapproval API call failed. <br>";
  echo "Detailed Error Message: " . substr($ErrorMsg,0,-3)."<br>";
  echo "Error Code: " . substr($ErrorCode,0,-3) . "<br>";
  echo "Error Severity: " . substr($ErrorSeverity,0,-3) . "<br>";
  echo "Error Domain: " . substr($ErrorDomain,0,-3) . "<br>";
  echo "Error Category: " . substr($ErrorCategory,0,-3) . "<br>";
