Trying to extract only certain values from a multidirectional array

[eric01]

Hi,

I am trying to extract the following array...

array('movies','romancemovies','scifimovies','comedymovies','books','thrillerbooks','autobiographies','magazines','music','rock','pop','soulmusic','reggaemusic','homegarden','kitchen','bedroom','bathroom','garden','other')

... from the mutlidirectional array that I put at the bottom of my post.
Basically, I want to isolate the words which are non-capital.

Please let me know if you have a suggestion..
Cheers

$Allcategories=array(array(array("Movies", 'movies'),
                       array("Action Movies", 'romancemovies'),
                       array("Sci-fi Movies", 'scifimovies'), 
                       array("Comedy Movies", 'comedymovies') 
                      ),
                 array(array("Books", 'books'),
                       array("Thriller Books", 'thrillerbooks'),
                       array("Auto Biographies", 'autobiographies'), 
                       array("Magazines", 'magazines'),
                       
                      ),
                 array(array("Music", 'music'),
                       array("Rock", 'rock'),
                       array("Pop", 'pop'), 
                       array("Soul Music", 'soulmusic'),
                       array("Reggae Music", 'reggaemusic'), 
                      ),
                 
                 array(array("Home & Garden", 'homegarden'),
                       array("Kitchen", 'kitchen'),
                       array("Bedroom", 'bedroom'), 
                       array("Bathroom", 'bathroom'),
                       array("Garden", 'garden'),
                       array("Other Furnitures", 'other') 
                      ),
             );

Hi again,

I found a partial solution. See below..
But I can't get all those results to fit into one array, as I said in the post above.
How do you put all the results from the loop into an array?

$numOfLayers=count($Allcategories);
for ( $layer = 0; $layer < $numOfLayers; $layer++ )
{
    	$numOfRows=count($Allcategories[$layer]);
		for ( $row = 0; $row < $numOfRows; $row++ ) 
		    {
    		$numOfColumns=count($Allcategories[$layer][$row]);      
			for ( $col = 1; $col < 2; $col++ ) 
				{
				$CategoriesLowerCase=($Allcategories[$layer][$row][$col]);
    			print_r($CategoriesLowerCase);
  				echo "<br />";
		    	}
		    }
}

I believe this gives you the required result:

$categories = array();
foreach ($Allcategories as $category) {
    foreach ($category as $item) {
        $categories[] = $item[1];
    }
}

echo '<pre>' . print_r($categories, true) . '</pre>'; //Prints out the result

Hi Bionoid,
Thank you very much for that!
I like the simplicity of it.

I actually found a solution too, but more complicated. Looking back at how my code was complicated, I feel ridiculous Here is it:

$numOfLayers=count($Allcategories);

for ( $layer = 0; $layer < $numOfLayers; $layer++ )
		{
  			$categoriesNonCapital[]=$Allcategories[$layer][0][1];
  			$categoriesCapital[]=$Allcategories[$layer][0][0];

		  	$numOfRows=count($Allcategories[$layer]);
		    for ( $row = 1; $row < $numOfRows; $row++ ) 
		    {
			        $numOfColumns=count($Allcategories[$layer][$row]);      
			        for ( $col = 0; $col < 1; $col++ ) 
			        {
			       	$categoriesNonCapital[]=$Allcategories[$layer][$row][1];
                                $categoriesCapital[]=$Allcategories[$layer][$row][$col];
		        	} 
     		}
		}

The point is that you tried and would be able to improve on it the next time you face a similar problem.

Yes, I am keeping that 3 nested for loop in mind in case I need it for something more useful

Thanks again.
