// stream_socket_client //$this->m_fp = @pfsockopen($this->m_host, $this->m_port, $errno, $errstr,10); $this->m_fp = @stream_socket_client($this->m_host.$this->m_port, $errno, $errstr, 10);这两句那个是原来的?$this->m_fp = @stream_socket_client($this->m_host.$this->m_port, $errno, $errstr, 10);应该为$this->m_fp = @stream_socket_client($this->m_host . ':' . $this->m_port, $errno, $errstr, 10);这样就可以了。只是你创建目录的部分没有执行,或有错如果 $this->m_fp = @pfsockopen($this->m_host, $this->m_port, $errno, $errstr,10); 是原来的那么在 //获取应答头状态信息 $httpstas = explode(" ",fgets($this->m_fp,256)); $this->m_httphead["http-edition"] = trim($httpstas[0]); $this->m_httphead["http-state"] = trim($httpstas[1]);有错,原因待查 function make_dir( $folder ){$reval = false;if ( !file_exists( $folder ) ){@umask( 0 );preg_match_all( "/([^\\/]*)\\/?/i", $folder, $atmp );应写作preg_match_all( "/([^\/]*)\/?/i", $folder, $atmp );或preg_match_all( "#([^/]*)/?#i", $folder, $atmp ); $this->m_fp = @stream_socket_client($this->m_host.$this->m_port, $errno, $errstr, 10);是原来的 上面发错了这句才是原来的 $this->m_fp = @fsockopen($this->m_host, $this->m_port, $errno, $errstr,10); 用dedecms的下载类 远程下载图片到本地失败 局域网内的图片可以下载成功 外网的图片无法下载 不知道你改动了多少地方按#13的用$this->m_fp = @stream_socket_client($this->m_host . ':' . $this->m_port, $errno, $errstr, 10);即可获取远程图片 晚上搜了dedecms的下载类确实存在这个问题,可是我试了楼上的那种,用我发布的代码还是无法获取图片,谢谢5星版主。 我用你的代码,当然是修改了那一行的已经成功的下载了$url="http://avatar.csdn.net/C/2/F/1_ibmfahsion.jpg";你自己在捉摸捉摸吧 服务器配置信息问题,假如你用的是phpnow appsrv xmapp wmapp=请你安装位纯净版的php运行环境,已经测试过,可以通过。 使用fpdf如何把html页面生成pdf 无法将数据加进数据库 怎么判断数据库有没有 谁能帮我传一下iestore php上传下载如何优化500人并发执行 二级域名伪静态问题 分享框架式网站系统的权限处理,尤其针对大型项目和二次开发项目 关于wamp环境配置 看看这段php代码 有没有只能缩略图的类啊 PHPEXCEL导出中文名称图片,这次真的是求高手了,慷慨给分 PHP新手求指导

这两句那个是原来的?
$this->m_fp = @stream_socket_client($this->m_host.$this->m_port, $errno, $errstr, 10);
应该为
$this->m_fp = @stream_socket_client($this->m_host . ':' . $this->m_port, $errno, $errstr, 10);
这样就可以了。只是你创建目录的部分没有执行,或有错如果 $this->m_fp = @pfsockopen($this->m_host, $this->m_port, $errno, $errstr,10); 是原来的
那么在
//获取应答头状态信息
$httpstas = explode(" ",fgets($this->m_fp,256));
$this->m_httphead["http-edition"] = trim($httpstas[0]);
$this->m_httphead["http-state"] = trim($httpstas[1]);
有错,原因待查
{$reval = false;
if ( !file_exists( $folder ) )
{
@umask( 0 );
preg_match_all( "/([^\\/]*)\\/?/i", $folder, $atmp );
应写作
preg_match_all( "/([^\/]*)\/?/i", $folder, $atmp );
或
preg_match_all( "#([^/]*)/?#i", $folder, $atmp );
这句才是原来的 $this->m_fp = @fsockopen($this->m_host, $this->m_port, $errno, $errstr,10);
$this->m_fp = @stream_socket_client($this->m_host . ':' . $this->m_port, $errno, $errstr, 10);
即可获取远程图片
