Question

我正在尝试上传一些字段和3张图片的表单。图像将通过FTP上传，当php上传到远程服务器时，使用ftp_connect（）连接到ftp时出现问题。当php在共享主机中时，它无法连接到服务器。但是当php在localhost中时，它没有显示任何错误。我现在正尝试将此工作在Localhost上，并首先将图像ftp_put输入远程服务器，以隔离错误。目前我收到了这个错误。

Warning: ftp_put() expects parameter 1 to be resource, boolean given in line 69

这是ftp_put($login,"abc.info/$photo",$_FILES["file"]["tmp_name"][$i],FTP_ASCII)

ftp_put()需要使用ftp_connect()获得的有效资源。如果您看到此错误消息，则您对ftp_connect()的调用失败。您需要使用ftp_connect()获取有效资源，如果不能，则需要弄清楚导致脚本无法连接到远程主机的原因，因为这是导致问题的根本原因。

为防止脚本失败，您应该在if语句中将尝试包装到FTP，以检查ftp_connect()是否已成功连接：

if (($resource = ftp_connect($host)) !== false) {
    // do FTP stuff
}

警告：ftp_put（）期望参数1为资源，布尔值为
