Question

So I need to modify the array in a memcached key-value pair. I need to remove one of the arrays inside the array. An example of what it looks like:

array(2) { [0]=> array(3) { ["username"]=> string(3) "Bob" ["id"]=> string(5) "14537" ["comment"]=> string(4) "cool"} [1]=> array(3) { ["username"]=> string(3) "Tom" ["id"]=> string(5) "14538" ["comment"]=> string(3) "yes"}}

If I know the values of username, id, and comment, how can I delete it? The generic queston: How can I delete array 0?

Considering the answer of doing a foreach loop, I tried

foreach($memcachedarray as $f){
  if ($f['id'] == '14537'){
    echo key($f);
  }
}

But it spits out username

Edit- Ok

I searched some more and found I need to do this:

foreach($memcachedarray as $key => $f){
if ($f['id'] == '14537'){
echo $key;
}
}

That works!

If the Id’s are unique across the system then you could use an associative array to store you data then unset the key, otherwise you would want to use a foreach loop to get the array key, then unset that key and recommit your new array back into memcache.
