Print PHP array structure

Question

I am new to PHP and stuck here, I want to view the values and structure of $_ITEM array. I have following php code.

    $this->dtgItem->AddColumn(new QDataGridColumn('Item', '<?= $_ITEM->ShortDescription ?>', 'CssClass="dtg_column_print"'));
            $this->dtgItem->AddColumn(new QDataGridColumn('Code', '<?= $_ITEM->RenderBarcode() ?>', 'Width=200', 'CssClass="dtg_column_print"', 'HtmlEntities=false'));
        $this->dtgItem->AddColumn(new QDataGridColumn('Qty', '<?= $_ITEM->Quantity ?>', 'Width=100','CssClass=dtg_column_print'));
        $this->dtgItem->AddColumn(new QDataGridColumn('Receipt #', '<?= $_ITEM->ReceiptNumber ?>', 'CssClass=dtg_column_print'));

I want to view structure of the $_ITEM Array.

I have tried following but it does not work.

echo "<pre style=\"font-size:12px;\">".print_r($_ITEM,true)."</pre>";

I would appreciate if someone can help to figure this out.

Thanks

Answer 1

change your code to:

echo "<pre style='font-size:12px;'>";
print_r($_ITEM); echo '</pre>';
