Question

I need some help setting up a PHP array. I get a little lost with multidimensional arrays.

Right now, I have an array with multiple products as follows:

If I do: print_r($products['1']); I get:

Array ( [0] => size:large [1] => color:blue [2] => material:cotton )

I can do print_r($products['2']); , etc and it will show a similar array as above.

I am trying to get it where I can do this:

echo $products['1']['color']; // the color of product 1

…and echo “blue”;

I tried exploding the string and adding it to the array as follows:

$step_two = explode(":", $products['1']);

foreach( $step_two as $key => $value){

$products['1'][$key] = $value;

}

I know I’m obviously doing the explode / foreach way wrong but I wanted to post my code anyway. I hope this is enough information to help sort this out.

Answer 1

You would be better of to build the array the right way, but to solve your problem you need to explode in the loop, something like:

foreach( $products['1'] as $value){
  $step_two = explode(":", $value);
  $products['1'][$step_two[0]] = $step_two[1];
}

You can wrap another foreach around it to loop over your whole $products array.

And you’d also better build a new array to avoid having both the old and the new values in your $products array.
