从PHP URL保存图像

Question

我需要将图像从PHP URL保存到我的PC.假设我有一个页面,http://example.com/image.php拿着一个"花"图像,没有别的.如何使用新名称(使用PHP)从URL保存此图像？

Answer 1

如果您已allow_url_fopen设置为true:

$url = 'http://example.com/image.php';
$img = '/my/folder/flower.gif';
file_put_contents($img, file_get_contents($url));

否则使用cURL:

$ch = curl_init('http://example.com/image.php');
$fp = fopen('/my/folder/flower.gif', 'wb');
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
fclose($fp);

Answer 2

copy('http://example.com/image.php', 'local/folder/flower.jpg');

Answer 3

$content = file_get_contents('http://example.com/image.php');
file_put_contents('/my/folder/flower.jpg', $content);

Answer 4

在这里,示例将远程图像保存到image.jpg.

function save_image($inPath,$outPath)
{ //Download images from remote server
    $in=    fopen($inPath, "rb");
    $out=   fopen($outPath, "wb");
    while ($chunk = fread($in,8192))
    {
        fwrite($out, $chunk, 8192);
    }
    fclose($in);
    fclose($out);
}

save_image('http://www.someimagesite.com/img.jpg','image.jpg');

Answer 5

Vartec的回答与卷曲并没有为我工作.由于我的具体问题,它确实略有改善.

例如,

当服务器上有重定向时(例如当您尝试保存Facebook个人资料图像时),您将需要以下选项集:

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

完整的解决方案变为:

$ch = curl_init('http://example.com/image.php');
$fp = fopen('/my/folder/flower.gif', 'wb');
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_exec($ch);
curl_close($ch);
fclose($fp);

Answer 6

我无法使任何其他解决方案起作用,但我能够使用wget:

$tempDir = '/download/file/here';
$finalDir = '/keep/file/here';
$imageUrl = 'http://www.example.com/image.jpg';

exec("cd $tempDir && wget --quiet $imageUrl");

if (!file_exists("$tempDir/image.jpg")) {
    throw new Exception('Failed while trying to download image');
}

if (rename("$tempDir/image.jpg", "$finalDir/new-image-name.jpg") === false) {
    throw new Exception('Failed while trying to move image file from temp dir to final dir');
}
