reference to an array element

[crackn101]

Hi Guys,
I had a quick question about referencing array elements.

I wanted to create a "shortcut" to a specific array element as a reference so as to Not create a copy of the data.

I just wanted to make sure that I understood this correctly.

Thanks.

Sample code:

$aData['texas']['dealer']['color']['red']="yes";
$aData['texas']['dealer']['color']['blue']="no";
$aData['texas']['dealer']['color']['green']="maybe";

$ref_colors = & $aData['texas']['dealer']['color'];

print $ref_colors['red'];
output: yes

looks ok. it is more usual to place the ampersand directly adjacent to the assignment operator. but this is just stylistic.

Thanks for the feedback. Prior to posting, I had googled numerous articles on referencing in php. Some where helpful and some were downright confusing.
Just making sure.

Thanks.
