You shouldn't need to do anything in the PHP code to achieve this; you should be able to do it using CSS stylesheets.

I'd suggest using CSS display:inline; or display:inline-block; on the <div> wrapper element that Drupal creates for its form elements.

Hope that helps.

[EDIT]

Something like this:

.form-item#search, .form-item#submit {
    display:inline;
}

..in your module's or theme's CSS file.

You can also wrap your fields in an in-line fieldset given below:

$form['filter'] = array(
'#type' => 'fieldset', 
'#title' => t('Filter options'), 
'#attributes' => array('class' => array('container-inline')), 
);
$form['filter']['search'] = array(
'#type' => 'textfield',
'#size' => 30,
'#maxlength' => 255
);
$form['filter']['submit'] = array(
'#type' => 'submit',
'#value' => t('Search'),
);
