[PHP] Automajickally POST to a remote form

[Kris Williams]

Heyas,

Once upon a time I used to be able to POST form data to external sites with 
ASP and an MSXML (or something) server object on IIS and I'm wondering if 
there's a similar sort of technique using PHP.  Would prefer it if I didn't 
have to use anything that isn't part of your typical PHP/Apache install (if 
there is such a thing) but will take what I can get.

The easiest description of what I'm attempting is:  user hits PHP page, 
page submits predefined search terms to Google and the results are 
displayed.  The user wouldn't have interacted with the search at all (ie: 
no button clicks) as it's all performed by the PHP script.

Thoughts?
Kris

You can post with PHP using cURL or doing it yourself manually.
Search the archives for this, as the previous answers to this are
more complete than what I have time to explain now. Here is a quick
example of the manual approach:

Thanks Chris.  A useful answer that's much appreciated :)

And yeh, after just after posting I realised my example using Google was a 
bad one with of the GET/POST thing.  Just tried to pick a generic site as 
an example as what I'm intending to do is probably too much hassle to 
explain in full.

[PHP] Figuring out tree depth.

[Kris Williams]

Hiyas,

I've made the following script to build a tree style navigation from a 
table of sections for an image gallery. There are root nodes of the tree 
which can have children, and those children can have their own children and 
so on to an infinte depth. A root node has a parentID of 0 and a child node 
has a parentID of the row id you want the child to belong to. (I've faked 
the arrays that would be returned from MySQL for this example).

The script is rendering items in the correct order, but I can't keep track 
of how deep in the tree each item is so I can indent them properly. A root 
node should have a 0 depth, it's child should have 1, and it's child again 
should be 2, then the next child of the root should go back to 1.  It seems 
to be working right until it gets to "rusted" (see eg).

I can figure that I'm adding items to the lastNode array but not removing 
them properly nor am I decrementing $x which is what should be keeping 
partial track of how deep I am. I figure this is where I'm going wrong but 
can't for the life of me figure it out. The calling of huntChild within 
itself is killing me.

The script at the moment is:

" . $depth . " - " . $key[1] . "";
$lastNode = array();
array_unshift($lastNode,$key[0]);
huntChildren($children,$key[0]);
   }

  function huntChildren($childArray,$rootID) {
   global $depth;
   global $lastNode;
   $x = 0;

  for ($i = 0; $i < sizeof($childArray); $i++) {
   // Suck out the first child node into a new array.
$tmpChild = array_shift($childArray);

   // Check to see if the parentID in $tmpChild matches the id of the node 
passed ($rootID) when the function is called.
   // A match means that the child has the node as a parent.
if ($rootID == $tmpChild[2]) {
 if ($lastNode[0] != $tmpChild[2]) {
  $x++;
  array_unshift($lastNode,$tmpChild[2]);
 }

 if ($x > 1) {
  $depth = sizeof($lastNode) - $x;
 } else {
  $depth = sizeof($lastNode);
 }

 echo $depth . " - " . $tmpChild[1] . "";

 // Go see if this child has children.
  huntChildren($childArray,$tmpChild[0]);
} else {
 // If there are no children to the node passed, put $tmpChild array 
back into the passed array of children for the next iteration.
  array_push($childArray,$tmpChild);
}
   }
  }
?>

and should generate:

0 - skatey
1 - parks
2 - regular visits
3 - concrete
4 - chipped
3 - metal
4 - rusted
2 - regular stacks
3 - blood spills
3 - guts everywhere
2 - regular zzz
1 - equipment

0 - me
1 - 0-10 years old
1 - 10-20 years old
2 - skeg phase

0 - friends


Aside from the depth problem the script functions just the way I want it 
to, but if anyone wants to point out or fix any major problems as well as 
my depth one, it'd be much appreciated.

Apologies for any shoddy indenting and the massive post. Trying to give as 
much info as I can.

Thanks,
Kris.
