I need to merge 2 arrays and i have found lot of examples here on stackoverflow, but nothing has worked for me, in my case, so i explain my case:

**Arrays (can be one, two, or three, or more...):**

```
Array ( [0] => name-file_icon_001_00.png- 
        [1] => name-file_icon_002_00.png-
        [2] => name-file_icon_003_00.png- )
Array ( [0] => rel
        [1] => rel
        [2] => rel )

```

**Or can be two:**

```
Array ( [0] => name-file_icon_001_00.png- 
        [1] => name-file_icon_002_00.png- )
Array ( [0] => rel
        [1] => rel )

```

**Or one:**

```
Array ( [0] => name-file_icon_001_00.png- ) 
Array ( [0] => rel )

```

Need to insert the relative value "`[0] => rel`" with "`[0] => name-file_icon_001_00.png-`"

**Expected result (merged):**

```
Array ( [0] => name-file_icon_001_00.png-rel
        [1] => name-file_icon_002_00.png-rel
        [2] => name-file_icon_003_00.png-rel )

```

Reading around the web, seems that not exist a native function for make this.
Please, hope in your help :)
