optgroup generated by php

I'm trying to generate optgroups and options with PHP from an array, and it generates it, but my optgroup is wrong. It display only the first word. In the page source it's correct.

$my_array = array(
    first optgroup => array(
        key1 =>value1,
        key2 => value2,
        key3 => value3,
    ),
    second optgroup => array(
        key1 =>value1,
        key2 => value2,
        key3 => value3,
    ),
);
foreach ($my_array as $optgroup => $other_array) {
    echo "<optgroup label=". $optgroup . ">";

    foreach ($other_array as $key => $value) {
        echo "<option value=" . $key . ">" . $value . "</option>";
}
    echo "</optgroup>";

in the source code is fine:

<optgroup label=first optgroup>
    <option value=key1>value1</option>
    <option value=key2>value2</option> 
    .......

but on my select box I see only "first", instead of "first optgroup"

Any ideas?? Thanks!!

try this,

$my_array = array(
    'first optgroup' => array(
        'key1' =>'value1',
        'key2' => 'value2',
        'key3' => 'value3',
    ),
    'second optgroup '=> array(
        'key1' =>'value1',
        'key2' => 'value2',
        'key3' => 'value3',
    ),
);

echo "<select>";
foreach ($my_array as $optgroup => $other_array) {
    echo "<optgroup label=". $optgroup . ">";
    foreach ($other_array as $key => $value) 
        echo "<option value=" . $key . ">" . $value . "</option>";
}
    echo "</optgroup>";
});
echo "</select>";

You'd need to embed some quotes:

echo "<optgroup label=\"{$optgroup}\">";
                      ^^-----------^^----

Note the backslash escapes on the embedded quotes. This'll generate

<optgroup label="foo bar">

instead of the 

<optgroup label=foo bar> 
                ^^^--- value for "label" attribute
                    ^^^---unknown random attribute

you're doing now
