display single value of php array

Question

I have array that I can display by code:

foreach($form->data as $key => $value){
echo 'Key is '.$key.' and Value is '.$value.'<br />';
}

And I get following display:

Key is language and Value is lv-LV
Key is Itemid and Value is 114
Key is option and Value is com_content
Key is pumpis_1 and Value is 1
Key is lietussargs and Value is 2

But I need to display only value of [Itemid] which in this case is 114 How can I do it? Thanks! Raivis

What have you tried? -- besides, you've got your answer: $form->data['Itemid'] or $form->data->Itemid; — Elias Van Ootegem

@EliasVanOotegem: $form->data->Itemid is not array syntax. — FtDRbwLXw6

@drrcknlsn: I know, but since the op is clearly using an object, and the results look like what a query returns (or a parsed xml doc, or...), it could well be an object that implements the ArrayAccess interface, in which case $var->data->colName would be valid — Elias Van Ootegem

echo $form->data['Itemid'];

Or if you mean inside the foreach loop (because you've got other stuff to do there), then use this:

foreach($form->data as $key => $value) {
    if( $key === 'Itemid' )
        echo $form->data['Itemid'];
}

Thanks @HappyTimeGopher ! Previously I tried various versions of foreach loop but somehow I didn't get to this option.. Now this one works! Thanks to all responses!!

You should read up on PHP arrays. The syntax is this:

echo $form->data['Itemid']
