# $config_overwrite

If set to `TRUE`, the default then variables read in from config files will overwrite each other. Otherwise, the variables will be pushed onto an array. This is helpful if you want to store arrays of data in config files, just list each element multiple times.

Example 12-4. Array of config #variables# This examples uses `{cycle}` to output a table with alternating red/green/blue row colors with `$config_overwrite` = `FALSE`. The config file.
    # row colors
    rowColors = #FF0000
    rowColors = #00FF00
    rowColors = #0000FF
The template with a `{section}` loop.
    <table>
      {section name=r loop=$rows}
      <tr bgcolor="{cycle values=#rowColors#}">
        <td> ....etc.... </td>
      </tr>
      {/section}
    </table>
