Recursion issue with using an array

[khovorka]

Hello,

I have the following basic code which calls a URL to get a json string back
and I parse it to put some values in an associative array. Then I have to loop through
the array to find those key=>value pairs where the value is 8..15 and call then function
again to get a new json string back and parse it again. This is repeated for a given
number of times that is selectable. When I get to the 2nd foreach loop to go through
the array to make the recursive request it only gets the first correct value and just does nothing.
I would appreciate other eyes looking at this. I could probably provide the json string if necessary.

Thanks in advance.

My code is the following:

<?php
$iarray = array();
$cnt = 0;

function get4gen($server, $id) {
global $iarray;
global $cnt;

echo "ID: ".$id."<br><br>";
$httpurl = $server."/platform/tree/ancestry?person=".$id;
echo $httpurl."<br>";

$xmldata=http($httpurl);
$json_a=json_decode($xmldata,true);

foreach($json_a[persons] as $p)
{
    if (strlen($p[id]) == 8) { 
		  $id = $p[id];
    $ascend = $p[display][ascendancyNumber];
    if ($id == 1) { $cnt++; }
    if ($cnt > 576) { break; }
    if (array_key_exists($id, $iarray) !== true) {
      $iarray[$id] = $ascend;  
    }
  }
}

foreach($iarray as $key=>$value) {
  if ($value > 7) {
    echo "ID2: ".$key.",  ".$value."<br>";
	    get4gen($server, $key);
	  }  
}

}
?>

Thanks,

I have rewritten some of the function and it appears that the issue I really need to
remedy is why it appears a new array is created for $iarray and $donearray each time
the function is called instead of just using the arrays passed in be reference?

Can anyone help in resolving this issue. See code below.

Thanks,
Kim H.

function get4gen($server, $id, &$iarray, &$donearray) {
static $cnt;

$httpurl = $server."/platform/tree/ancestry?person=".$id;

echo $httpurl."<br>";

$xmldata=http($httpurl);
$json_a=json_decode($xmldata,true);
foreach($json_a[persons] as $p)
{
$id = $p[id];
echo "ID: ".$id."<br>";
if (strlen($id) == 8) {
$ascend = $p[display][ascendancyNumber];
$avals = "$id,$ascend";
if ($ascend == 1) { $cnt++; }
if ($cnt > 576) { break; }
if (!in_array($id, $donearray)) {
array_push($iarray, $avals);

array_push($donearray, $id);

}
}
}
echo "IARRAY HERE>>>>>><br>";
var_dump($iarray);
echo "<br><br>DONEARRAY HERE>>>>>><br>";
var_dump($donearray);
echo "<br><br>";

foreach($iarray as $pair) {
$arr = explode(",",$pair);
echo "ID2: ".$arr[0].", ".$arr[1]."<br>";
if (($arr[1] > 7) && !in_array($arr[0], $donearray)) {
get4gen($server, $arr[0], $iarray, $donearray);
}

}
}
