[drupal-devel] What the difference between '==' and '==='

[Gordon Heydon]

Hello,

I was just doing some work, and work some reason the form_select would
select every thing.

Here is what I coded.

form_select('', 'result][' .$payment->txnid, '', array('' => t('select
result'), '1' => t('cleared'), '0' => t('dishonoured'))

And for some reason every option was selected.

I changed line 1329 in common.inc from ($value == $key ? '
selected="selected"' : '')) to ($value === $key ? '
selected="selected"' : '')) and it started working.

Is my form_select call wrong, or is there some difference between == and
===

Thanks.
