PHP 图像调整器错误“加载页面时重置与服务器的连接 - Error with PHP image resizer "The connection to the server was reset while the page was loading."

Error with PHP image resizer "The connection to the server was reset while the page was loading."

我想用PHP来调整图像大小。这是我的代码，但是当我启动它时，Firefox给出错误说：

加载页面时，与服务器的连接已重置。

为什么不起作用？错误从何而来？

function resize_image($filename, $newwidth, $newheight){
    list($width, $height) = getimagesize($filename);
    if($width > $height && $newheight < $height){
        $newheight = $height / ($width / $newwidth);
    } else if ($width < $height && $newwidth < $width) {
        $newwidth = $width / ($height / $newheight);   
    } else {
        $newwidth = $width;
        $newheight = $height;
    }
    $thumb = imagecreatetruecolor($newwidth, $newheight);
    $source = imagecreatefromjpeg($filename);
    imagecopyresized($thumb, $source, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
    return imagejpeg($thumb);
}

和 HTML：

<img class="top_logo" src="<?php echo resize_image('images/top_logo.png' , '100' , '100'); ?>" alt="logo"/>

您提到的错误可能是由脚本其他部分中的某个无限循环引起的。但是我已经更正了您的代码。

请记住，imagecreatefromjpeg()只接受jpeg文件

<?php
    function resize_image($filename, $newwidth, $newheight)
    {
        list($width, $height) = getimagesize($filename);
        if($width > $height && $newheight < $height){
            $newheight = $height / ($width / $newwidth);
        } else if ($width < $height && $newwidth < $width) {
            $newwidth = $width / ($height / $newheight);   
        } else {
            $newwidth = $width;
            $newheight = $height;
        }
        $thumb = imagecreatetruecolor($newwidth, $newheight);
        $source = imagecreatefromjpeg($filename);
        imagecopyresized($thumb, $source, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
        ob_start();
        imagejpeg($thumb);
        return 'data:image/gif;base64,' . base64_encode(ob_get_clean());
    }
    ?>
    <img class="top_logo" src="<?php echo resize_image('logo.jpeg' , '100' , '100'); ?>" alt="logo"/>
