Arrays and Complex Indices

[bigoxygen@gmail.com]

Hi...
the following line doesn't give its intended effect
$selected[ $out['month'] ] = 'SELECTED';

but this line will:
$selected[ $out['month'] + 0 ] = 'SELECTED';

How do I make sure $out['month'] is evaluated correctly without added a
0 to guide php?

thanks

what do you get for
print_r($out)

and
print_r($select ed)

and how do you populate the arrays in the first place?

$out:
Array ( [course_id] => [html_title] => Change Profile [trail] => Home >
Change Profile:

[hooks] => Back to Home [day] => 12 [month] => 05 [year] => 1983
[birmonth] => )

1

$selected

Array ( [1] => [2] => [3] => [4] => [5] => SELECTED [6] => [7] => [8]
=> [9] => [10] => [11] => [12] => )

Right, got it.

When PHP looks at $selected[$out['month']], it evaluates $selected['05'] by
the looks of it, i.e. the 'month' value in $out is a string, not a number.
To fix this, try either
1 - set the value as a number in the first place:
$out['month'] = 5;

2 - cast the value to an integer
$selected[int($out['month']] = 'SELECTED';

Hope this helps

Should be $selected[(int) $out['month']]. int() is a function called "int".

Good point. Wasn't thinking.
