How to modify dolibarr invoice

Recently had to make amendments in dolibarr CRM Invoice design & text.

At first galance it seems that it is going to be too hard for me to manage this.

After some research on internet I came to know that there are 2 ways to change Invoice.

First option - Changing Odt file.
Second option - Changing the php code directly.

Being a PHP Professional I have chosen php way.  

I have learnt a lot of things that can be modified easyly so I thought to inform others who are willing to change the dolibarr invoice too. You may follow below steps to edit invoice.

How to change date format in dolibarr invoice

First change that I made is changed the Date format of Invoice from MM/DD/YYYY to DD/MM/YYYY

To do so I have defined my own function

function _changeDateFormat($str)
{
    $str=explode("/", $str);
    $str2=$str[1]."/".$str[0]."/".$str[2];
    return $str2;
}

Then I have replaced below line & added my defined function with date output:

$pdf->MultiCell(100, 3, $outputlangs->transnoentities("DateInvoice")." : " . $this->_changeDateFormat(dol_print_date($object->date,"day",false,$outputlangs)), '', 'R');
