希望一切都会好起来...我想做一些事情，比如我有一个 PHP 图像上传器，这里是上传器的链接：http://alitechn.w08.wh-2.com/undo_testing/uploader/upload.php
因此，当有人打开链接以使图像显示为空白时，我想在静态HTML中添加一些图像，但通常当有人上传图像时，新图像将替换静态图像..！
以下是上传.php文件的完整代码：
<?php
$fulltarget = '';
@$submit=$_POST['sub'];
if(isset($submit))
{
$name=$_FILES['img']['name'];
$type=$_FILES['img']['type'];
$size=($_FILES['img']['size'])/1024;
$ext=end(explode('.',$name));
if (($ext == "gif")
|| ($ext == "jpeg")
|| ($ext == "jpg")
|| ($ext =="png")
&& ($size > 30))
{
############################## File Renaming ###################################################
$newname=uniqid();
//$ext=end(explode('.',$name));
$fullname=$newname.".".$ext;
$target="pics/";
$fulltarget="http://alitechn.w08.wh-2.com/undo_testing/uploader/{$target}{$fullname}";
if($should_display_static){
$fulltarget="http://www.ipic-uk.com/images/homepage/upload_your_photo.png";
}
if(move_uploaded_file($_FILES['img']['tmp_name'],$fulltarget))
{
echo "Success";
}
else
{
echo "Failed";
}
############################## File Renaming end ###################################################
}
else{
echo "not successful";
}
}

将$fulltarget更改为要显示的图像的绝对路径。然后，每当确定要显示静态图像时，请更改$fulltarget以指向静态图像。
$fulltarget="http://alitechn.w08.wh-2.com/undo_testing/uploader/{$target}{$fullname}";
然后检查是否要显示静态图像（您没有指定条件）
if($should_display_static)[
$fulltarget="http://path/to/static/image.jpg";
}
然后显然将您的 img 代码更改为：
<img id='image1' src='".$fulltarget."' width='300px' height='400px'/>
