PHP imagecreatefromjpeg()从命令行运行,从HTTP失败

问题描述 投票:0回答:1

我正在尝试使用PHP脚本通过GD图像功能缩放目录中的所有JPG图像。当我从命令行执行脚本时,该脚本有效,但通过HTTP调用时,脚本不起作用。记录表明在呼叫imagecreatefromjpeg()时失败。 GD似乎已安装并正确配置,因为对getimagesize()的调用成功。由于相同的原因,它似乎是有效的图像文件。

非常感谢任何帮助。

相关代码(为便于阅读,删除了一些代码:

while (false !== ($entry = readdir($fh))) {
    $pathinfo = pathinfo($entry);
    if ('jpg' === strtolower($pathinfo[ 'extension' ])) {
        $log->info(sprintf('Processing file "%s"', $entry));
        $srcName = implode(DIRECTORY_SEPARATOR, [$config[ 'stageDir' ], $pathinfo[ 'basename' ]]);
        if ( ! file_exists($srcName)) {
            $log->warning(sprintf('File "%s" not found', $srcName));
            continue;
        }

        if ( false === ( $info = getimagesize($srcName))) {
            $log->warning('This file is not a valid image');
        }
        var_dump($info);
        echo imagecreatefromjpeg($srcName) . "\n";

        if (false === ($srcImg = imagecreatefromjpeg($srcName))) {
            $log->warning(sprintf('Cannot read image file "%s"', $srcName));
            continue;
        }
    }
}

命令行输出:

C:\Apache24\htdocs\kiosk\public>php convert.php
C:\Apache24\htdocs\kiosk\public\convert.php:75:
array(7) {
  [0] =>
  int(3072)
  [1] =>
  int(2304)
  [2] =>
  int(2)
  [3] =>
  string(26) "width="3072" height="2304""
  'bits' =>
  int(8)
  'channels' =>
  int(3)
  'mime' =>
  string(10) "image/jpeg"
}
Resource id #26

通过HTTP执行时记录文件:

[2020-01-01 07:22:50] gallery.INFO: Processing file "IMG_2748.JPG" [] []
[2020-01-01 07:22:50] gallery.WARNING: Cannot read image file "../staging\IMG_2748.JPG" [] []

Windows 10,Apache 2.4,PHP 7.2这是来自php -i的GD信息:

在PHP.net网站上的功能文档的注释部分中找到a solution。它没有说明为什么它可以从命令行运行,但不能从HTTP请求中运行,也没有说明函数调用失败的原因。但是,它确实提供了一种解决方法。
