[SOLVED] loop in nested associative array question

[alpineedge3]

hello,

 

I have an associative array that looks like this:

 

Array
(
    [1940s] => Array
        (
            [tag_id] => 8
            [count] => 1
            [fontsize] => 16px
        )

    [academic] => Array
        (
            [tag_id] => 13
            [count] => 1
            [fontsize] => 16px
        )
...
}

 

I need to be able to change the $array[val]['fontsize'] in a loop. I don't think I'm doing it right, because when I print_r after the loop the fontsize values are not changed. However, the loop echos the desired strings.

 

foreach($tagArray as $array => $val){
$zscoreInt = round($val['count']-$stdev);
$$val['fontsize'] = $avgFontsize + $zscoreInt . 'px';
        echo $$val['fontsize'] . '<br />';
}

 

What's wrong? Thanks.

Why are you using two $s in front of some of your variables?

[wildteen88]

Chnage your code to this:

foreach($tagArray as $array => $val)
{
$zscoreInt = round($val['count'] - $stdev);

$tagArra[$array]['fontsize'] = $avgFontsize + $zscoreInt . 'px';
}

 

When using $val, this is a new instance, when ever you update this variable it wont affect the array. What you'll have to do is refer to the array instead.
