PHP array_merge combining arrays with same values -

I have two arrays which I am adding to one and I have several that may possibly be duplicates. Looked and it makes great sense. This is an example that I am trying to achieve.

  array1 ('make and model 1', 'make and model 2', 'make and model 1' ...); Array 2 ('serial number 1', 'serial number 2', 'serial number 3' ...); Array 3 ('Other make and model 1', 'Other make and model 2', 'other AK and model 3' ...); Array 4 ('Other Serial Number 1', 'Other Serial Number 2', 'Other Serial Number 3' ...); $ Make = array_merge ($ array1, $ array3); $ Serial = array_merge ($ array2, $ array4); Foreach ($ make, $ serial) $ model = & gt; $ Number): if (($ model == "") || $ model == "other"): ... code ... endiff; Endforeach;  

Now you can see that I have two make and model 1, what is happening is that it is in combination with arrays, but with the first make and model 1 Instead of showing what I am trying to do with a lower item than my client's clients. What is the way to fix this?

There may be repeated values ​​in the array, but for obvious reasons, the repeated key array_combine Overlays the value according to each duplicate key.

To make the key of your array_combine serial number, assuming that all your serial numbers are unique, a simple solution:

  foreach ( Array_combine ($ serial, $ formatted) $ number = & gt; $ as model):  

If you have between one and a few between "Make" and "Serial Number" If you have relationships, you may want to consider changing your data structure so that each serial number can match an array.
