PHP - 打印对齐 - 从文本文件到收据打印机

Question

I am creating a text file with the following code:

$textcreate = "**************************************
" . PHP_EOL;            
$textcreate .= "Item             Amt     Qty     Total" . "
" . PHP_EOL;
if (isset($print_table_for_txt_file["ordereditems"])) {
    foreach ($print_table_for_txt_file["ordereditems"] as $key => $value) {
         $textcreate .= $value['item_name'] . " " . number_format((float) $value['withoutTax_itemPrice'], 2, '.', '')  . "
" . PHP_EOL;
    }
}
$textcreate .= "**************************************
" . PHP_EOL;
$textcreate .= "Amount Payable:             " . round($print_table_for_txt_file['api']['0']['GrandTotal']) . ".00
" . PHP_EOL;
$textcreate .= "**************************************
" . PHP_EOL;

$myfile = fopen("example.txt", "w") or die("Unable to open file!");
fwrite($myfile, $textcreate);

The output of the file is :

************************************** Item Amt Qty Total pen 10.00 1 10.00 ************************************** Amount Payable: 10.00 **************************************

But I want the output to be :

************************************** 
Item             Amt     Qty     Total   
pen             10.00     1      10.00
************************************** 
Amount Payable:                  10.00 
**************************************

What should I do

Browser shrinks all consecutive whitespaces (including and ) in HTML into a single space. You can:

• use header('Content-Type: text/plain') to make the browser treat the output as plain text (leaving all whitespaces as they are)
• use the <pre> HTML tag to achieve the same in HTML
