Pushing values into an array...

[rJonesX]

So I have a loop going through an XML document...

for($y=0; $y<sizeof($entry); $y++)
{
if ($entry[$y]->type == XML_ELEMENT_NODE)
{

    if ($entry[$y]->name() == "order") 
    { 

$order_value = $entry[$y]->get_content();

???????

   }
}

}

The question marks are for this....

I need to take this newly created $order_value and put it into an array of all the "order" values extracted from the xml document...

So, for example, say for $entry[0]->get_content(); the "order" value is equal to 213124... then i want it added to, lets say...

$matching_array[0] = 213124

and if $entry[1]->get_content(); the "order" value is equal to 9... then I want it added to

$matching_array[1] = 9

and so on and so forth, so eventually I have an array, stored in the variable $matching_array, of all of the order values...

The end purpose of this is to take these values, use the sort() expression as was indicated earlier to me in the forums, i think by TTT, and then run another for loop where we match these values in descending order against the XML entries (so it will spit out the records in the order i want them)....

For the time being though, i just need to know how to use the loop to push values into the $matching_array

thanks

$matching_arry[] = $entry[$y]->get_content();

That will build the array consecutively as the loop progresses. Once the loop is finished, all data will be stored in order of entry in an array called $matching_array.

I have pasted the code below... imagine it is set up with $new_node being a parent node with 5 children including the "title", "order", "month", "day", "year" - the order is the amalgamation of year, month, then day into something like 20021208 so that I can order the entries easily, but this has already been done in the xml, the $stop_value = 1 and the $ending_value is equal to a loop already going on that is looping through these parent nodes. (The xml is a set of short news stories, <stories><story><title>whatever</title>...</story><story>...</story></stories> if that makes sense...

so the function loops through the children of the parent node, each time encountering a node with the name "order" it places the value into the array "matching_array" or at least it should...

Interestingly, when I run this script... it shows the countdown till the var_dump like it should...

1,5
1,4
1,3
1,2
1,1

but then it prints out the var_dump($matching_array); and it only has 1 value in it! ?

any ideas what is going wrong? Why the $matching_array[] isnt collecting the ->get_content(); from each "order" node?

I have pasted the code below.

function get_dates($new_node, $stop_value, $ending_value)
{
$new_node_kids = $new_node->children();

		for($a=0; $a<sizeof($new_node_kids); $a++)
		{

			if ($new_node_kids[$a]->type == XML_ELEMENT_NODE)
				{
					if ($new_node_kids[$a]->name() == "order")
						{
						$matching_array[] = $new_node_kids[$a]->get_content();
						echo $stop_value . "." . $ending_value . "<br>";					
							if ($stop_value == $ending_value){ echo var_dump($matching_value);}

						}

				}
		}
}

function get_dates($new_node, $stop_value, $ending_value)
{
global $matching_array;
$new_node_kids = $new_node->children();

		for($a=0; $a<sizeof($new_node_kids); $a++)
		{

			if ($new_node_kids[$a]->type == XML_ELEMENT_NODE)
				{
					if ($new_node_kids[$a]->name() == "order")
						{

						array_push($matching_array, $new_node_kids[$a]->get_content());
						echo $stop_value . "." . $ending_value . "," . $new_node_kids[$a]->get_content() . "<br>";					
							if ($stop_value == $ending_value){ echo var_dump($matching_array); }

						}

				}
		}
}
