php - PHP 函数 fwrite 中的 IF THEN 表达式

Question

如何将 IF THEN 表达式放入 PHP 函数 fwrite 中？下面给出的代码不能正常工作。请查看行 fwrite($fh, "$row[0]...)。

    $myFile = "testFile.php";
    $fh = fopen($myFile, 'w') or die("can't open file");

    fwrite($fh, "lat    lon title   description iconOffset  icon\n");
    foreach ($result4 as $row):
        fwrite($fh, "$row[0]    $row[1] $row[2] Resource average speed is: $row[3] km/h -10,-10 if($row[4]==0) images/markerRed.png else images/markerGreen.png\n");
    endforeach;

    fclose($fh);
?>

Answer 1

$image = ($row[4] == 0) ? "images/markerRed.png" : "images/markerGreen.png";
/* ... $row[3] ... ".$image."\n"; */
