When a print_r() an array $stats, I get the following:
Array ( [0] => Array ( [like] => 71 [dislike] => 372 [total] => 443 [like_s] => 78 [dislike_s] => 291 [total_s] => 369 [final] => 11 ))
I want to get the [dislike_s] value and put it into a variable.
I have attempted this:
$statss = $stats['dislike_s'];
But it did not work. I have also tried $statss = $stats['dislike_s'][0]; without result.
What am I doing wrong?
You are missing a level of your array
Array ( [0] => Array ( [like] => 71
//^ this level
Also you are using the wrong variable, as you said your array is stored in $stats so
$total_revision = $stats[0]['dislike_s'];
$stats is a two dimensional Array, i.e. it is an array of arrays. You can see this from the output of print_r. You have something that looks like `Array ( [0]=>Array(...)). Therefore, when accessing an element of the inside array, you can think of it like this:
$inner_array=$stats[0];
$total_revisions=$inner_array['dislike_s'];
Php gives you a shorthand for combining these steps(pretty much all languages do) and it looks like $total_revisions=$stats[0]['dislike_s'] but intuitively it's the same thing. You're saying "in the array $stats[0] give back the value of array element 'dislike_s'"
$total_revision[0]['dislike_s'], the first array index is0.
