通过运行以下脚本,我得到了 500 Internal Server Error,即使我一次下载并插入 DB 80 图像:
<?php
function download_remote_file($file_url, $save_to)
{
$content = file_get_contents($file_url);
file_put_contents($save_to, $content);
}
function microtime_float()
{
list($usec, $sec) = explode(" ", microtime());
return ((float)$usec + (float)$sec);
}
require_once('sqlconnect.php');
$time_start = microtime_float();
$query="SELECT * FROM GAMES WHERE GAME_IMAGE LIKE '%cache%' LIMIT 0, 80";
$result = mysql_query($query);
while($row = mysql_fetch_array($result))
{
$game_img = $row['GAME_IMAGE'];
$gameDB_id = $row['GAME_DBID'];
chdir($_SERVER['DOCUMENT_ROOT'].'/img/game/');
if(!file_exists($gameDB_id))
{
mkdir($gameDB_id);
}
if(strlen(strstr($game_img,'boxart')) == 0)
{
$game_img = $game_img.'/boxart/original/front/'.$gameDB_id.'-1.jpg';
}
$game_img_path = $_SERVER['DOCUMENT_ROOT'].'/img/game/'.$gameDB_id;
chmod($game_img_path,0777);
$game_img_name = $gameDB_id.'.jpg';
$gamefullpath = 'http://www.someSite.nl/img/game/'.$gameDB_id.'/'.$game_img_name;
if(!file_exists($game_img_path.'/'.$game_img_name ))
{
download_remote_file($game_img, realpath($game_img_path) . '/'.$game_img_name);
$bytes = filesize($game_img_path.'/'.$game_img_name );
$KB = round($bytes / 1024, 2);
if($KB > 50)
{
echo "The ID number ".$gameDB_id. " has an invalid image URL, look it up on gamedb.net! <br />";
}
}
$query2 = "UPDATE GAMES SET GAME_IMAGE = '$gamefullpath' WHERE GAME_DBID = '$gameDB_id' AND GAME_DBID";
$result2 = mysql_query($query2) or die("error!");
//$nr_of_files = count($game_img_path);
//echo "Nr of images downloaded:".$nr_of_files;
}
mysql_close($con);
$time_end = microtime_float();
$time = $time_end - $time_start;
echo "Downloading and adding to the database took ".$time." seconds <br />";
$message = "The specified images have been downloaded!";
echo $message;
?>
我做错了什么会迫使服务器停止吗?或者,如果它没有效率,我该怎么做才能做到这一点。或者问题可能出在某些服务器配置上。

我在这条线之后放了一个骰子,错误似乎在这里:
download_remote_file($game_img, realpath($game_img_path) . '/'.$game_img_name);
