] | No, there is no such facility. If you need per-data-object protections, you'll have to allocate at least a page per object (using `mmap`). If you also want to have some protection against access beyond the end of the object (for arrays) you might allocate at least one more page than what you need, align the object so i... |

] | First of all it seems that you are creating lots of string objects in the inner loop. You could try to build list of prefixes first:

```
Additionally you could use `string`'s method `endswith` instead of creat... |
28,728,398 | I have 2 arrays :
1. $valid\_sku\_array
2. $qb\_sku\_array
I want to `intersect` them, and print out the `bad` one (diff)
Then I do this :
```
// Case Sensitive
$intersect_sku_array_s = array_intersect( $valid_sku_array, $qb_sku_array );
dd($intersect_sku_array_s); ... array (size=17238)

] | You're problem already begins with your intersect call! There you will lose your "real" array data, because you compare everything in lowercase and assign it also in lowercase.
So your array\_diff won't find anything, because it's case sensitive and if you make it case insensitive you still doesn't have the real data.... |
