PHP excluding specific variable values from foreach statement

I am trying to exclude fields from a form from being required. Currently the entire array payment runs through this for each statement. I am trying to keep the fields extra, extra2 and extra3 from being required. The can be set to null or defined as whatever string if empty. This is what I have currently: 

  foreach($p as $key => $value) {
    $value = trim($value);
    if($value == '') {
      $keyName = preg_replace('/([A-Z])/', " $1", $key);
      $this->_errors['Payment ' . $keyName] = __('Payment ','cart66') . $keyName . __(' required','cart66');
      $this->_jqErrors[] = "payment-$key";
    }

This is what I have tried, but to no avail:

 foreach($p as $key => $value) {
    $value = trim($value);
    if($value == '' && $p != 'extra' || 'extra2' || 'extra3') {
      $keyName = preg_replace('/([A-Z])/', " $1", $key);
      $this->_errors['Payment ' . $keyName] = __('Payment ','cart66') . $keyName . __(' required','cart66');
      $this->_jqErrors[] = "payment-$key";
    }
else if ($p['extra'] == '') {
 $_p['extra'] = NULL; 
}
else if ($p['extra2'] == '') {
 $_p['extra2'] = NULL; 
}
else if ($p['extra3'] == '') {
 $_p['extra3'] = NULL; 
}

}

It's my syntax isn't it? The database itself is set to accept null and is not primary or unique.

One good way would just be to check at the top of the loop and continue if you're in on a field that should be excluded. 

$exclude = array('field1', 'field2', ...);
foreach ($p as $key => $value)
{
    if (in_array($key, $exclude)) { continue; }

    // your code... 
}
