Question

Think I’m missing a basic concept. I want to generate html by traversing through a few different arrays of data. They don’t use numbers as indexes so numerical looping doesn’t work. I cant figure out how to use a foreach() here either. How can I traverse $price and $description when the indexes aren’t numbers?

Sample:

$traverser= 0;
while($traverser < $number_of_records)
{
    print $traverser . " - " . $price[$traverser] . "<br />";
    print $description[$traverser];
    $traverser++;
}

Partial Sample of the Array Structure:

object(phpQueryObject)#2799 (13) { ["documentID"]=>  string(32) "1d62be942498df890cab4ccb78a007a2" ["document"]=>  &object(DOMDocument)#3 (0) { } ["charset"]=>  &string(5) "utf-8" ["documentWrapper"]=>  &object(DOMDocumentWrapper)#2 (17) { ["document"]=>  &object(DOMDocument)#3 (0) { } ["id"]=>  string(32) "1d62be942498df890cab4ccb78a007a2" ["contentType"]=>  string(9) "text/html" ["xpath"]=>  &object(DOMXPath)#4 (0) { } ["uuid"]=>  int(0) ["data"]=>  array(0) { } ["dataNodes"]=>  array(0) { } ["events"]=>  array(0) { } ["eventsNodes"]=>  array(0) { } ["eventsGlobal"]=>  array(0) { } ["frames"]=>  array(0) { } ["root"]=>  &object(DOMElement)#5 (0) { } ["isDocumentFragment"]=>  &bool(true) ["isXML"]=>  bool(false) ["isXHTML"]=>  bool(false) ["isHTML"]=>  bool(true) ["charset"]=>  &string(5) "utf-8" } ["xpath"]=>  &object(DOMXPath)#4 (0) { } ["elements"]=>  array(560) { [0]=>  object(DOMElement)#2239 (0) { } [1]=>  object(DOMElement)#2240 (0) { } [2]=>  object(DOMElement)#2241 (0) { } [3]=>  object(DOMElement)#2242 (0) { } [4]=>  object(DOMElement)#2243 (0) { } [5]=>  object(DOMElement)#2244 (0) { } [6]=>  object(DOMElement)#2245 (0) { } [7]=>  object(DOMElement)#2246 (0) { } [8]=>  object(DOMElement)#2247 (0) { }

Since it looks like you need the array keys as well, since you’re referencing multiple different arrays, you want the $a as $k => $v syntax for foreach:

foreach($description as $key => $desc)
{
    print $key . " - " . $price[$key] . "<br />";
    print $desc;
}
