Mutliple Options not converted into an array

When doing this:
```bash
./script.sh -p /home/test -p /home/123 -d 21g -d 44g
```

I have this output: 
```
0	/home/ test /home/ 123
```

I use this code to iterate over the array:
```bash
for i in "${!OPTS_PATH[@]}"; do 
        printf "%s\t%s\n" "$i" "${OPTS_PATH[$i]}"
done
```
