Question

我有一个png图像将被下载当用户点击下载图标时，现在该图像正在其打开的同一网页上下载。我想在新的网页上下载图片。这是下面的代码，我找不到在哪里更改代码，使其在新的网页上下载。我认为应该修改的代码是......

header("Content-disposition: attachment; filename=\"$iconName".$sizeName.".png\"");

如果要查看完整代码，请按以下步骤操作。请帮我解决这个问题....

<?php
    ob_start();

    require "../config.php";

    error_reporting(0);

    $icon = $_GET['icon'];
    $iconName = str_replace(".png", "", $_GET['in']);

    $dimensions = $_GET['size'];
    $padding = $_GET['padding'];

    $bgShape = $_GET['bgShape']; if(!$bgShape) $bgShape = 'TransparentCNT.png';
    $bgColorR = $_GET['bgColorR'];
    $bgColorG = $_GET['bgColorG'];
    $bgColorB = $_GET['bgColorB'];

    $iconColorR = $_GET['iconColorR'];
    $iconColorG = $_GET['iconColorG'];
    $iconColorB = $_GET['iconColorB'];
