Parse new-line and output 1 value per XML attribute WordPress
- SOLVED
$gtin is a simple string variable that may have only 1 value, or may have multiple values separated by newline characters.
Current Code:
$output.= ' <g:gtin>' . $gtin . '</g:gtin>' . PHP_EOL;
Current Output:
<g:gtin>00748927027884
00748927027877</g:gtin>
Desired Output:
<g:gtin>00748927027884</g:gtin>
<g:gtin>00748927027877</g:gtin>
How can I make this happen?

try this
<?php
$gtin = @explode('\n',$gtin);
foreach( $gtin as $val )
$output.= ' <g:gtin>' . $val . '</g:gtin>' . PHP_EOL;
?>

Thanks, that produces still the same output:
<g:gtin>00748927027884
00748927027877</g:gtin>
Which I'm guessing means my new line is not encoded as a '\n', but not sure.

try this
$arr = preg_split("/\r\n|\n|\r/", $gtin);
foreach( $arr as $val )
$output.= '<g:gtin>' . $val . '</g:gtin>' . PHP_EOL;
echo $output;

You can also try this one
It is slightly modified version of Arnav.
<?php
$gtin = @explode("\r\n",$gtin);
foreach( $gtin as $val )
$output.= ' <g:gtin>' . $val . '</g:gtin>' . PHP_EOL;
?>
Bob comments:
if still not work remove "\r" and try again
<?php
$gtin = @explode("\n",$gtin);
foreach( $gtin as $val )
$output.= ' <g:gtin>' . $val . '</g:gtin>' . PHP_EOL;
?>
Notice double quote here. \n should be in double quote not in single quote.

Thanks, both
$arr = preg_split("/\r\n|\n|\r/", $gtin);
and
$gtin = @explode("\r\n",$gtin);
Worked :-)

You can even try this also.
$arr = @explode(PHP_EOL,$gtin);
foreach( $arr as $val )
$output.= '<g:gtin>' . $val . '</g:gtin>' . PHP_EOL;
