Hey ZF Team,

Think I have found a bug in Zend_View_Helper_FormSelect.

Example of this would be passing an array say a list of 0 to 5 as the value on the select element.

$multiItems = array( 'def' => 'Please select..', '0' => '0', '1' => '1', '2' => '2', '3' => '3', '4' => '4', '5' => '5' );

If I then created an element like this:

    $this->addElement('select', 'selectElement', array(
        'label' => 'Number list',
        'multiOptions' => $multiItems,
        'disable' => array('-'),
    ));

Then the first item (with the value of hyphen '-') will be disabled but so will the item with the value of 0.

After a little investigation this seems to be with the Zend_View_Helper_FormSelect in the _build method on line 172 of my version of the view helper you have:

if (in_array($value, $disable)) { $opt .= ' disabled="disabled"'; }

If I change this to:

    if (in_array($value, $disable, true)) {
        $opt .= ' disabled="disabled"';
    }

So that the strict option is enabled then it fixes the problem.

Not sure if this is a bug or a feature that I haven't seen docs for.
