Variable Multidimentional Array

[dyluck]

Hi There.

 

How does one go about creating a variable multidimentional array?

Im building a crawler of sorts.  It will crawl category trees and then follow the links it finds to lower depths.  Of course, I need to keep track of the category name as well and then hopefully when it hits the bottom it has nicely stored the whole thing in parent and child nodes within the array.

 

I been searching high and low for a decent description or example.

 

Really hope someone can help.

Have you checked out the Array page on php.net?

http://php.net/manual/en/language.types.array.php

 

Arrays can contain arrays, so you have true multidimensional arrays. You can also use an integer or a string for a key.

 

print_r is handy for printing an array's contents to the browser, for example, so you can see what's going on with it at any time.

 

Best thing to do is to start creating some arrays and playing with adding and accessing values to them.

 

Hope this helps...

Trust me, I am the biggest fan of trial and error.  I have scowered the array section of the php manual. 

I just don't know whats happening....

 

here is my code:

 

foreach(catrules($_SESSION['SMID']) as $catrule) {
$querys = "SELECT * FROM CR_SCRAPER_CATSET WHERE CATSETID = $catrule[CATSETID]" ;
$results = mysql_query($querys) or die(mysql_error());
while($pinfos = mysql_fetch_array( $results ))
{  
if($x == 0 ) {
	//initialization of the categories
	$categories =  array(Apple, Orange, Kiwi, Banana, Plum); 
	foreach($categories as $key => $val){  $cats[$z][$key] =  $val; $z++;  }


	}

	if($catrule['DEPTH'] == 3) {
		for($i=2; $i <= $catrule['TYPE']; $i++) {	
		foreach($cats as $cat => $link) {
		$cats[$z][$key] = spliter($pinfos['FDELIM'],$pinfos['SPLIT'],$pinfos['EDELIM'],$pinfos['ESPLIT'],$pinfos['SEPERATOR'],$pinfos['FIRSTNUM'],$pinfos['PATTERN'],$pinfos['LSPLIT'],$pinfos['CSPLIT'],sourceget($link),$link,$catrule['LINKSETTING'],$link,$catrule['URL']);
		$z++;
		} //end for j loop
		}//end for loop catrule 'type'
	}//end if Catrule depth 3

	if($catrule['DEPTH'] == 2) {
		foreach($cats as $cat => $link) {			
		$cats[$z][$cat] = spliter($pinfos['FDELIM'],$pinfos['SPLIT'],$pinfos['EDELIM'],$pinfos['ESPLIT'],$pinfos['SEPERATOR'],$pinfos['FIRSTNUM'],$pinfos['PATTERN'],$pinfos['LSPLIT'],$pinfos['CSPLIT'],sourceget($link),$link,$catrule['LINKSETTING'],$link,$catrule['URL']);

		$z++;
		} //end for j loop
		}//end for loop catrule 'type'
	//}//end if Catrule depth 3

$x++;
}//end catrule while
} // end foreach catrules

traverse($cats);	

 

So, what its supposed to spit out is something like:

 

    * 0 =>

          o Apples => http://www.fruitsite.com/home.php?cat=348

            * 5 =>

                  o Red => http://www.fruitsite.com/home.php?cat=349

                  o Green => http://www.fruitsite.com/home.php?cat=350

                  o Yellow => http://www.fruitsite.com/home.php?cat=356

    * 1 =>

          o Oranges => http://www.fruitsite.com/home.php?cat=622

    * 2 =>

          o Kiwi => http://www.fruitsite.com/home.php?cat=461

    * 3 =>

          o Banana => http://www.fruitsite.com/home.php?cat=268

    * 4 =>

          o Plum => http://www.monergismbooks.com/home.php?cat=250

 

So on and so fourth as it goes deeper and deeper into the links.
