我有一个 PHP 脚本(如下),它使用 imagecreatefromjpeg 并且它可以工作。然后我添加了几个 mysql 语句,它不再起作用(我看到损坏的图像图标)。
如何混合 imagecreatefromjpeg 并与 mysql 查询相关。谢谢!
<?php
//Report any errors
ini_set ("display_errors", "1");
error_reporting(E_ALL);
$user="root";
$password="pw";
$database="piwigo";
//Adding these two lines breaks the image:
//mysql_connect(localhost,$user,$password);
//@mysql_select_db($database) or die( "Unable to select database");
$current_image = imagecreatefromjpeg("sample.jpg");
// place code for saving the montage image as a file or outputting to the
// browser here.
header("Content-type: image/jpeg");
imagejpeg($current_image);
imagedestroy($current_image);
mysql_close();
?>
最佳答案
//Report any errors
ini_set ("display_errors", "1");
error_reporting(E_ALL);
您报告错误,它会生成输出然后图像损坏。
例如
mysql_connect(localhost,$user,$password);
必须是
mysql_connect("localhost",$user,$password);
您可以运行下面的代码来查看是否获得除图像之外的任何输出
<?php
//Report any errors
ini_set ("display_errors", "1");
error_reporting(E_ALL);
$user="root";
$password="pw";
$database="piwigo";
//Adding these two lines breaks the image:
mysql_connect(localhost,$user,$password);
@mysql_select_db($database) or die( "Unable to select database");
// $current_image = imagecreatefromjpeg("sample.jpg");
// place code for saving the montage image as a file or outputting to the
// browser here.
// header("Content-type: image/jpeg");
// imagejpeg($current_image);
// imagedestroy($current_image);
mysql_close();
?>
可能的工作代码
<?php
// Don't Report any errors
error_reporting(0);
$user="root";
$password="pw";
$database="piwigo";
//Adding these two lines breaks the image:
mysql_connect("localhost",$user,$password) or die("Unable to connect database");
@mysql_select_db($database) or die("Unable to select database");
$current_image = imagecreatefromjpeg("sample.jpg");
// place code for saving the montage image as a file or outputting to the
// browser here.
header("Content-type: image/jpeg");
imagejpeg($current_image);
imagedestroy($current_image);
mysql_close();
?>
