以下前提是你有服务器的最高权限，可以修改php.ini 方法一：　　第一步：　　php.ini文件中查找　　allow_url_fopen = On 　　使其值为On 　　第二步：　　php.ini文件中查找　　extension=php_openssl.dll 　　如果前面有分号，去掉分号　　第三步：　　重启web服务器，apache或IIS 方法二：　　1. vi php.ini 　　找到 allow_url_fopen 这个参数设置成 On，即　　allow_url_fopen = On 　　2. 让你的php支持 opensll扩展。　　默认，是没有openssl扩展的，只能重新编译安装。　　yum install openssl openssl-devel 　　cd /usr/local/src/php-5.2.14/ext/openssl 　　/usr/local/php/bin/phpize 　　./configure –with-openssl –with-php-config=/usr/local/bin/php-config 　　make && make install 　　看提示，把编译成的openssl.so 拷贝到你在php.ini 中指定的 extension_dir 下　　3. vi php.ini 　　加入　

multi-thread, multi-curl crawler in PHP

问题 Hi everyone once again! We need some help to develop and implement a multi-curl functionality into our crawler. We have a huge array of "links to be scanned" and we loop throw them with a Foreach. Let's use some pseudo code to understand the logic: 1) While ($links_to_be_scanned > 0). 2) Foreach ($links_to_be_scanned as $link_to_be_scanned). 3) Scan_the_link() and run some other functions. 4) Extract the new links from the xdom. 5) Push the new links into $links_to_be_scanned. 5) Push the

How do I use fsockopen() to open a Telnet connection with a password?

阅读更多关于 How do I use fsockopen() to open a Telnet connection with a password?

问题 I'd like to access a camera through it's Telnet capability. The problem is, it has Password-protection. This is no problem when doing it via Terminal, as I just use telnet 10.30.blah.blah then enter my password when prompted. But in php, I don't see the opportunity to input a password. $con = fsockopen("10.30.blah.blah", 25); $msg = "camera move left"; fwrite($con, $msg); Anybody have any ideas? UPDATE : I tried just using fputs to output the password as @Cfreak said, but still to no avail.

Sending emails from PHPMailer using proxies IP addresses

阅读更多关于 Sending emails from PHPMailer using proxies IP addresses

问题 I need to send emails from PHPMailer using proxies IP addresses, I know that to do so, I need to use the fsockopen function so I can connect to the SMTP account, I also know that if I have to connect to the proxy I have to use the fsockopen function again. But using it fsockopen inside another fsockopen is not doable. I have transparent proxy and require no authentication. I need to send this to a distant SMTP server of an external Email Service Provider. The code I have tried : <?php //SMTP

CURL vs fsockopen chunking

阅读更多关于 CURL vs fsockopen chunking

问题 This may seem kind of weird.. but I need to evaluate/parse chunks being sent over HTTP with PHP. It's of note to say that the HTTP stream may never end. Is there any way I can parse chunks as I get them with CURL? Or do I have to resort to some home-brewed fsockopen() solution? 回答1: Take a look at the option CURLOPT_WRITEFUNCTION . You can define a callback that will be called when there's new data in the response. See the manual. 来源： https://stackoverflow.com/questions/3350029/curl-vs

php中 curl， fsockopen ，file_get_contents 三个函数比较

阅读更多关于 php中 curl， fsockopen ，file_get_contents 三个函数比较

赵永斌: 有些时候用file_get_contents()调用外部文件,容易超时报错。换成curl后就可以.具体原因不清楚 curl 效率比file_get_contents()和fsockopen()高一些,原因是CURL会自动对DNS信息进行缓存(亮点啊有我待亲测) 范佳鹏: file_get_contents curl fsockopen 在当前所请求环境下选择性操作，没有一概而论：具我们公司开发KBI应用来看：刚开始采用：file_get_contents 后来采用：fsockopen 最后到至今采用：curl （远程）我个人理解到的表述如下（不对请指出，不到位请补充） file_get_contents 需要php.ini里开启allow_url_fopen,请求http时，使用的是http_fopen_wrapper，不会keeplive.curl是可以的。 file_get_contents()单个执行效率高，返回没有头的信息。这个是读取一般文件的时候并没有什么问题，但是在读取远程问题的时候就会出现问题。如果是要打一个持续连接，多次请求多个页面。那么file_get_contents和fopen就会出问题。取得的内容也可能会不对。所以做一些类似采集工作的时候，肯定就有问题了。 sock较底层，配置麻烦，不易操作。返回完整信息。潘少宁-腾讯： file

Can I open socket in PHP from a specific IP (if the machine has two IPs)?

阅读更多关于 Can I open socket in PHP from a specific IP (if the machine has two IPs)?

I'm using PHPMailer and it uses fsockopen to access the SMTP server. But the machine has two IPs with different reverse DNS records. So in email headers I got the following: Received: from one-server.tld (HELO another-server.tld) ... I need to hide one-server.tld in favor of another-server.tld . But I need both IPs with their current RDNS settings. I think its not possible using fsockopen . But its possible in curl , fopen and stream functions. What you need is stream_socket_client() function. Here are some ways to achieve it. Using context parameters which can be used in fopen function family

问题 Here is the code that I am using: if (!($fp = fsockopen('ssl://imap.gmail.com', '993', $errno, $errstr, 15))) echo "Could not connect to host"; $server_response = fread($fp, 256); echo $server_response; fwrite($fp, "C01 CAPABILITY"."\r\n"); while (!feof($fp)) { echo fgets($fp, 256); } I get the first response: OK Gimap ready for requests from xx.xx.xx.xx v3if9968808ibd.15 but then the page times out. I have searched through stream_set_blocking, stream_set_timeout, stream_select, fread, etc.
