Question

<?php

   $dbhost = 'xx';
   $dbuser = 'xx';
   $dbpass = 'xxxx';

   $conn = mysql_connect($dbhost, $dbuser, $dbpass);
   if(! $conn )
   {
     die('Could not connect: ' . mysql_error());
   }

   mysql_select_db('url') or trigger_error("Unable to switch to the database: " . mysql_error()); 


function arr($num){

$ch = curl_init();
$r= rand (1,90);
$url="https://www.googleapis.com/customsearch/v1?q=Gravity%20Falls%20Latest%20images&num=10&start=".$r."&safe=off&cx=x:2hdsc4__avm&filter=0&c2coff=disable&alt=json&key=x";

curl_setopt($ch, CURLOPT_URL, $url);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$output = curl_exec($ch);

curl_close($ch);

        $a=intval($num);
        $data = json_decode($output, true);
        $se= $data['items'][$a]['pagemap']['cse_image'][0]['src'];

        $query = mysql_query("SELECT `url` FROM `url` WHERE `url`='".$se."'");

  if (mysql_num_rows($query) != 0)
  {
     $rr= rand (1,10);
     arr($rr);
  }else{

      mysql_query("INSERT INTO `url`(`url`) VALUES ('".$se."')");
      return $se;

      }
}

$rr= rand (1,10);
echo arr($rr);





require_once("src/facebook.php");

$config = array();
$config['appId'] = 'x';
$config['secret'] = 'x';
$config['fileUpload'] = true;
$fb = new Facebook($config);

$params = array(
"access_token" => "xxx",
"message" => "",
"url" => "".arr($rr)."", 
);

try {

$ret=$fb->api('/1111/photos', 'POST', $params);
echo 'Photo successfully uploaded to Facebook Album';
}
catch(Exception $e) {
echo $e->getMessage();
}
mysql_close($conn);

?>

我在5到6台服务器上尝试了这个，所有人都给了我500 error，但当我删除sql连接时，它可以工作！我提供了所有正确的mysql信息。

那为什么它显示500？

修改

如果我发表评论

    $query = mysql_query("SELECT `url` FROM `url` WHERE `url`='".$se."'");

  if (mysql_num_rows($query) != 0)
{
 $rr= rand (1,10);
 arr($rr);
 }else{

  mysql_query("INSERT INTO `url`(`url`) VALUES ('".$se."')");
  return $se;

  }

有效！

查看您的url表格。如果只获得已存储在该表中的arr url值，则递归调用$se函数的方式可能会无限递归。（如果你得到一个可以转换成空字符串的值）

始终发生Server 500错误
