将php脚本结果写入文本文件

Question

The php script displays the results on screen, but does not export the results to a text file. Doing php c:\myscript.php > output.txt works, but does not contain the line breaks (as opposed to the way it appears on screen).

What I am missing here to export the results to a text file?

The script that works on screen with command line:

<?php

$list1 = array('a1', 'a2', 'a3');
$list2 = array('b1', 'b2',);
$list3 = array('c1', 'c2', 'c3');

foreach ($list1 as $i) {
    foreach ($list2 as $j) {
        if ( $j == $i ) { continue; }
        foreach ($list3 as $k) {
            if ( $k == $j ) { continue; }
            if ( $k == $i ) { continue; }
            echo "$i$j$k
";
        }
    }
}

?>

I tried to insert this at the end, but getting error.

$sListText = file_get_contents("output.txt");
echo nl2br($sListText);

I tried this, getting empty text file:

$output = null;
foreach....
file_put_contents("output.txt", $output, FILE_APPEND);

On linux machine php myscript.php > output.txt works fine and with line breaks, you use windows, so you must change

echo "$i$j$k
";

to

echo "$i$j$k
";

Hope it helps.
