array data matches but array created in loop doesn't work

[Reed Law]

I have the exact same data in two arrays, but only the array created
like so will work:

$spaw_imglibs = array(
array(
'value' => '/youth/pics/Member pics/',
'text' => 'Member pics',
),
array(
'value' => '/youth/pics/Group pictures/',
'text' => 'Group pics',
),
);

This array creates an exact copy of the array above:

$spaw_imglibs = array();
$test= array();
$base = './pics/';
if(is_dir($base)){
$dh = opendir($base);
while (false !== ($dir = readdir($dh))) {
if (is_dir($base . $dir) && $dir !== '.' && $dir !== '..') {
$subs = $dir ;
$subbase = $base . $dir . '/';
$test[value]="/youth/pics/$dir/";
$test[text]="Subject: $dir";
array_push($spaw_imglibs,$test);
}
}
closedir($dh);
}
The code above just browses the directory tree of the server and fills
in the same data as the first array, by finding the directory name and
filling in $dir in the path. I would like to use this looped array
because the directory tree will be expanding and I don't want to have
to manually add to the array every time a new directory is created.


I tested the arrays like so:
$spaw_imglibs = array(
array(
'value' => '/youth/pics/Member pics/',
'text' => 'Member pics',
),
array(
'value' => '/youth/pics/Group pictures/',
'text' => 'Group pics',
),
);

They both display the same output, but the second array doesn't work
for SPAW Editor version 1.0.3. The $spaw_imglibs array is used to
store directories of images for this WYSIWYG editor. I can't tell why
the 2nd array won't work, unless the syntax of
$test[value]="/youth/pics/$dir/" somehow creates a different array
from the syntax 'value'=>'/youth/pics/Member pics/'. The $dir
variable holds exactly "Member pics", so it seems they would be the
same. When I use the second array in SPAW, the image browser window
comes up with no directories shown. The first array shows the two
directories properly in the image browser.
Could array_push be changing some structure of the array? Could PHP
be converting the spaces into something weird that messes up SPAW?
Any help will be greatly appreciated.
