foreach($models as $md)
{
   $articles[$md->id] = $md->name;
}

or (if above doesn't work)

foreach($models as $md)
{
   $tmp = $md->id;
   $articles[$tmp] = $md->name;
}

Under which circumstances would the second code work, but not the first one?

BTW: You should be writing “foreach (” (and “if (”, “switch (” etc.) so that 
it is not mistaken by the reader for a function call.

Not with javascript. Nonsense propagates like wildfire in this field.

Looks like you have an array of sub arrays, and want to change it to an 
associative array where sub array element 1 is the key and sub array 
element 2 is the data.

I'd guess you want to define a new associative array, then step through 
the existing array assigning elements in the new associative array 
according to the values in each sub array of the existing array.

You might want to do some sort of sanity check before you start that none 
of the sub arrays in the existing array have the same values in the key 
element, as otherwise you may end up losing data.
