Is there a pretty print for PHP?

Answer 1

Here is a version of pp that works for objects as well as arrays (I also took out the commas):

function pp($arr){
    if (is_object($arr))
        $arr = (array) $arr;
    $retStr = '
';
    if (is_array($arr)){
        foreach ($arr as $key=>$val){
            if (is_object($val))
                $val = (array) $val;
            if (is_array($val)){
                $retStr .= '
' . $key . ' => array(' . pp($val) . ')
';
            }else{
                $retStr .= '
' . $key . ' => ' . ($val == '' ? '""' : $val) . '
';
            }
        }
    }
    $retStr .= '
';
    return $retStr;
}
