php syntax for new line is not working

问题

I am having a rather simple question

can anyone tell me why this is not displaying each variable on a new line, well except for the  .

$curtime = gmdate("d/m/Y H:i:s");
    //capture the PayPal returned information as order remarks
$oremarks =
"##$curtime##<br>".
"PayPal Transaction Information...\n".
"Txn Id: ".$ppInfo["txn_id"]."\n".
"Txn Type: ".$ppInfo["txn_type"]."\n".
"Item Number: ".$ppInfo["item_number"]."\n".
"Payment Date: ".$ppInfo["payment_date"]."\n".
"Payment Type: ".$ppInfo["payment_type"]."\n".
"Payment Status: ".$ppInfo["payment_status"]."\n".
"Currency: ".$ppInfo["mc_currency"]."\n".
"Payment Gross: ".$ppInfo["payment_gross"]."\n".
"Payment Fee: ".$ppInfo["payment_fee"]."\n".
"Payer Email: ".$ppInfo["payer_email"]."\n".
"Payer Id: ".$ppInfo["payer_id"]."\n".
"Payer Name: ".$ppInfo["first_name"]." ".$ppInfo["last_name"]."\n".
"Payer Status: ".$ppInfo["payer_status"]."\n".
"Country: ".$ppInfo["residence_country"]."\n".
"Business: ".$ppInfo["business"]."\n".
"Receiver Email: ".$ppInfo["receiver_email"]."\n".
"Receiver Id: ".$ppInfo["receiver_id"]."\n";

//Update database using $orderno, set status to Paid
//Send confirmation email to buyer and notification email to merchant
//Redirect to thankyou page
echo $oremarks;

thanks Richard

Carriage returns have no effect if you're viewing this output as HTML, so try turning them into   tags with nl2br...

echo nl2br($oremarks);

回答2:

Because you are outputting the result in the browser window, try " " instead of "\n".

回答3:

Presumably because you are generating HTML source code from PHP, and not plain text.

In HTML, a new line is treated like any other whitespace. You need a   element or something that is display: block (or similar) to trigger a line break.

回答4:

Try alternating the Double quotes for your array values, use single quotes instead

$curtime = gmdate("d/m/Y H:i:s");
    //capture the PayPal returned information as order remarks
$oremarks =
"##$curtime##<br>".
"PayPal Transaction Information...\n".
"Txn Id: ".$ppInfo['txn_id']."\n".
"Txn Type: ".$ppInfo['txn_type']."\n".
"Item Number: ".$ppInfo['item_number']."\n".
"Payment Date: ".$ppInfo['payment_date']."\n".
"Payment Type: ".$ppInfo['payment_type']."\n".
"Payment Status: ".$ppInfo['payment_status']."\n".
"Currency: ".$ppInfo['mc_currency']."\n".
"Payment Gross: ".$ppInfo['payment_gross']."\n".
"Payment Fee: ".$ppInfo['payment_fee']."\n".
"Payer Email: ".$ppInfo['payer_email']."\n".
"Payer Id: ".$ppInfo['payer_id']."\n".
"Payer Name: ".$ppInfo['first_name']." ".$ppInfo['last_name']."\n".
"Payer Status: ".$ppInfo['payer_status']."\n".
"Country: ".$ppInfo['residence_country']."\n".
"Business: ".$ppInfo['business']."\n".
"Receiver Email: ".$ppInfo['receiver_email']."\n".
"Receiver Id: ".$ppInfo['receiver_id']."\n";

//Update database using $orderno, set status to Paid
//Send confirmation email to buyer and notification email to merchant
//Redirect to thankyou page
echo $oremarks;

But I would recommend using a HEREDOC instead of concatenating a string

    $curtime = gmdate("d/m/Y H:i:s");
        //capture the PayPal returned information as order remarks
    $oremarks =<<<OREMARKS
##$curtime##
PayPal Transaction Information...
Txn Id: $ppInfo['txn_id']
Txn Type: $ppInfo['txn_type']
Item Number: $ppInfo['item_number']
Payment Date: $ppInfo['payment_date']
Payment Type: $ppInfo['payment_type']
Payment Status: $ppInfo['payment_status']
Currency: $ppInfo['mc_currency']
Payment Gross: $ppInfo['payment_gross']
Payment Fee: $ppInfo['payment_fee']
Payer Email: $ppInfo['payer_email']
Payer Id: $ppInfo['payer_id']
Payer Name: $ppInfo['first_name'] $ppInfo['last_name']
Payer Status: $ppInfo['payer_status']
Country: $ppInfo['residence_country']
Business: $ppInfo['business']
Receiver Email: $ppInfo['receiver_email']
Receiver Id: $ppInfo['receiver_id']
OREMARKS;

    //Update database using $orderno, set status to Paid
    //Send confirmation email to buyer and notification email to merchant
    //Redirect to thankyou page
    echo $oremarks;

In html, newlines never go to line. You have to put   in your source.

Notice that php can also works independently from http server as a command line utility and does not necessarily generate html.

Thus if you set your content type in web server to plain/text instead of html using header("Content-type: plain/text"); at the beginning of your file your text would go to line as you expected.

回答6:

\n only shows a newline in the source.
is the "newline" character for HTML.

回答7:

The '\n' is just creating a new line in the html code, it is not creating a new line that is visible. You need to use html to get the new line to be visible. You can use the the html break   or you can make each line a paragraph  your text...  or you can use a list:

 <ul>
   <li> your text... </li>
   <li> next item... </li>
   <li> more stuff.. </li>
 </ul>

Try putting in the following:

<?php
echo "<pre>";

?>
