} else {
// array of valid extensions
$validExtensions = array('.jpg', '.jpeg', '.gif', '.png');
// get extension of the uploaded file
$fileExtension = strrchr($_FILES['image']['name'], ".");
// check if file Extension is on the list of allowed ones
if (in_array($fileExtension, $validExtensions)) {
$newNamePrefix = time() . '_';
$manipulator = new ImageManipulator($_FILES['image']['tmp_name']);
// resizing to 200x200
$newImage = $manipulator->resample(200, 200);
// saving file to uploads folder
$manipulator->save('uploads/' . $newNamePrefix . $_FILES['image']['name']);
echo 'Done ...';
} else {
echo 'You must upload an image...';
}

您将文件另存为

'uploads/' . $newNamePrefix . $_FILES['image']['name']

因此，您可以通过返回具有 'src' 属性的 IMG 标签来简单地显示它：

echo '<img src="./uploads/' . $newNamePrefix . $_FILES['image']['name'] . '">';
