2-d arrays -- issues of printing and deleting

I have an array of arrays, like so:

$arr = array(array('blue','green','yellow'),
array('fall','winter','summer'),
array('Ford','GMC','Toyota')
)

I want to print_r(), say, only the seasons and the cars, how would I do this?

Also, how could I delete one of the arrays?

Thanks for your help!

well,

PHP Code:


		
			
echo('<pre>');
print_r($arr[1]); //Seasons
print_r($arr[2]); //Cars
echo('</pre>');

To delete one, it would probaly require you to do some loop or stuff like that..

To delete a part of the array use unset:

php Code:

unset($arr[1]);

php.net/unset

PHP Code:


		
			
unset($arr[1]);

The only issue is if I'm not mistaken is, the array will persist with the current numerical order - meaning it'll be something like this

PHP Code:


		
			
$arr[0]
$arr[2]

you can use a combination of array_splice/array_merge to properly delete array elements and have them be in correct numerical order.
