更新:我简化了代码(尝试过)

我正在尝试下载数组中设置的一系列图像,但显然不对:

function savePhoto($remoteImage,$fname) {
    $ch = curl_init();
    curl_setopt ($ch, CURLOPT_NOBODY, true);
    curl_setopt ($ch, CURLOPT_URL, $remoteImage);
    curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, 0);
    $fileContents = curl_exec($ch);
    $retcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    curl_close($ch);
    if($retcode==200) {
        $newImg = imagecreatefromstring($fileContents);
        imagejpeg($newImg, ".{$fname}.jpg",100);
    }
    return $retcode;
}

$filesToGet = array('009');
$filesToPrint = array();

foreach ($filesToGet as $file) {
        if(savePhoto('http://pimpin.dk/jpeg/'.$file.'.jpg',$file)==200) {
            $size = getimagesize(".".$file.".jpg");
            echo $size[0] . " * " . $size[1] . "<br />";
        }
}

我收到以下错误:

  

警告:imagecreatefromstring()   [function.imagecreatefromstring]:   空字符串或无效图像   C:\的Inetpub \虚拟主机\ dehold.net \的httpdocs \ ripdw \的index.php   在第15行

试试这个:

function get_file1($file, $local_path, $newfilename)
{
    $err_msg = '';
    echo "<br>Attempting message download for $file<br>";
    $out = fopen($newfilename, 'wb');
    if ($out == FALSE){
      print "File not opened<br>";
      exit;
    }

    $ch = curl_init();

    curl_setopt($ch, CURLOPT_FILE, $out);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_URL, $file);

    curl_exec($ch);
    echo "<br>Error is : ".curl_error ( $ch);

    curl_close($ch);
    //fclose($handle);

}//end function

file_get_contents

您应该尝试使用file_get_contents来代替CURL(更简单,但它可以完成工作):

 function savePhoto($remoteImage,$fname) {        
      $fileContents = file_get_contents($remoteImage);        
      try {        
        $newImg = imagecreatefromstring($fileContents);
        imagejpeg($newImg, ".{$fname}.jpg",100);        
      } catch (Exception $e) {        
        //what to do if the url is invalid        
      } 
}

我终于得到了它的工作,在你们所有人的帮助下,还有一些窥探: - )

我最终使用了CURL:

function savePhoto($remoteImage,$fname) {
    $ch = curl_init();

    curl_setopt ($ch, CURLOPT_URL, $remoteImage);
    curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, 0);
    $fileContents = curl_exec($ch);

    $retcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);

    curl_close($ch);
    if($retcode == 200) {
        $newImg = imagecreatefromstring($fileContents);
        imagejpeg($newImg, $fname.".jpg",100);
    }

    return $retcode;
}


$website = "http://www.pimpin.dk/jpeg";
$filesToGet = array('009');
$filesToPrint = array();

foreach ($filesToGet as $file) {
        if(savePhoto("$website/$file.jpg",$file)==200) {
            $size = getimagesize($file.".jpg");
            echo $size[0] . " * " . $size[1] . "<br />";
        } else {
            echo "File wasn't found";
        }
}
