Question

我有一段这段代码。

它将图像收费到我的网络服务器并将名称保存到我的sql中。

所有工作除了调整大小时间。我在http://php.net/manual/en/function.imagecopyresampled.php

上找到了这个功能

非常感谢任何帮助。

感谢。

1。您必须先将文件移动到新目录，然后才能调整其大小。把你的调整大小放在这一行之下：

$result = @move_uploaded_file($tmpName, $imagePath);

否则调整大小代码会尝试访问尚不存在的文件。

2。您必须将新图像写为文件输出，因此请替换该行

 $imagePath = imagejpeg($image_p, null, 100);

用这个

imagejpeg($image_p, $imagePath, 100);

在没有库的情况下使用php调整图像大小
