I have removed blank lines before and after prefix/suffix operators.

Removed spaces

// wrong
if (! isset($this->$sName)) {

// fixed
if (!isset($this->$sName)) {
Removed spaces

// wrong
$iShopId = - 1; 
$iCnt ++;

// fixed
$iShopId = -1;
$iCnt++;
Removed linebreaks

// wrong
protected $_aFieldNames = array(
    'oxid' => 0
); // Splitted to three lines. Should be fixed as would create lot of
fake code changes.

// fixed
protected $_aFieldNames = array('oxid' => 0);

// possible side-effect
protected $_aFieldNames = array('oxid' => 0, 2, 3, 4, 5, 6, 7, 8, 9,
10);
