FPDF Footer get variable declared on foreach line

Question

I declared a variable named "$shop" like this:

foreach($shop_list as $shop)
    function_that_writes_pdf_files($shop);

And I want to use $shop in my footer. Is it possible ? I could use a variable by using

global $variable

But it doesn't work with $shop If you have an answer or seen the answer somewhere, please share it

Answer 1

Create a small function when you extend the fPDF class with your own name. The function does nothing more than set a public variable that holds the value of $shop which you may then use in your footer function.

class my_pdf extends FPDF {
    public $shop;
    public function setshop($input) {$this->shop = $input;}
    function Footer() {
        $this->Cell(15,5,$this->shop,0,0,'L');  // Using the value of shop here
    }  // end of the Footer function
}

$ourpdf = new my_pdf('P','mm','Letter');
foreach($shop_list as $shop) {
    $ourpdf->setshop($shop); // This sets the value of $shop to the fPDF class you created so the footer function may use it
    function_that_writes_pdf_files($shop);
}
