空间不支持fsockopen函数解决办法

fsockopen not support function Method Discover space solve

今天买了一个空间发现空间不支持fsockopen函数,后来网上找了几种解决空间不支持fsockopen方法,下面给大家分享一下,希望对各位朋友有所帮助呀。

为了服务器安全考虑很多主机商禁用了php的fsockopen函数,昨天进博客,使用cos-html-cache生成静态文件,尼玛提示:

Warning: fsockopen() has been disabled for security reasons in D:...cos-html-cachecos-html-cache.php on line 35

换了其他版本的cos-html-cache,还是不行。后来找到下面的方法。 = =、(结果不行,因为函数都被禁用了。)

大家试下,很少有我这样的情况的,用其他替代函数。

一、如何禁用fsockopen()

下面是两种常用的禁用fsockopen的方法。

1、修改php.ini,将  disable_functions =   后加入  fsockopen  
2、修改php.ini,将  allow_url_fopen = On   改为  allow_url_fopen = Off  

二、如何解决fsockopen函数被禁用

1、如果服务器没有同时禁用pfsockopen,那么直接将fsockopen函数替换为pfsockopen。
具体操作:搜索程序中的字符串  fsockopen(   替换为  pfsockopen(   。示例如下
修改前:

 代码如下 复制代码

$fp = fsockopen($host, 80, $errno, $errstr, 30);

修改后:
 

$fp = pfsockopen($host, 80, $errno, $errstr, 30);


2、如果服务器同时禁用了pfsockopen,那么用其他函数代替,如stream_socket_client()。注意:stream_socket_client()和fsockopen()的参数不同。
具体操作:搜索程序中的字符串  fsockopen(   替换为  stream_socket_client(   ,然后,将原fsockopen函数中的端口参数“80”删掉,并加到$host。示例如下
修改前:
 

 代码如下 复制代码

$fp = fsockopen($host, 80, $errno, $errstr, 30);

修改后
 

$fp = stream_socket_client($host."80", $errno, $errstr, 30);


3、如果PHP版本低于5.0,fsockopen被禁用,又没有stream_socket_client()怎么办呢?自己写一个函数实现fsockopen的功能,参考代码:

 代码如下 复制代码
 
function b_fsockopen($host, $port, &$errno, &$errstr, $timeout) {
 $ip = gethostbyname($host);
 $s = socket_create(AF_INET, SOCK_STREAM, 0);
 if (socket_set_nonblock($s)) {
  $r = @socket_connect($s, $ip, $port);
  if ($r || socket_last_error() == EINPROGRESS) {
   $errno = EINPROGRESS;
   return $s;
  }
 }
 $errno = socket_last_error($s);
 $errstr = socket_strerror($errno);
 socket_close($s);
 return false;
}

具体操作:

1.首先找到使用fsockopen函数的代码段,将上面代码加至其上端,搜索该代码段中的字符串  fsockopen(   替换为  b_fsockopen(  

2.因为fsockopen函数返回文件指针所以可以被文件函数操作,但是这个b_fsockopen函数没能返回文件指针,需要继续修改代码段:用socket_read(   替换掉  fread(   ,用socket_write(   替换掉fwrite(   ,用socket_close(   替换掉fclose(   。


解决方案二:

fsockopen大多数应用是的获取远程页面数据,对于获取远程页面这种应用,PHP还有其他函数可以完美替代:
 
方法1:

 代码如下 复制代码
$str = file("http://www.bKjia.c0m");
$count = count($str);
for ($i=0;$i      $file .= $str[$i];
     }
echo $file;
?>

 
 
方法2:

 代码如下 复制代码
$str = file_get_contents("http://www.bKjia.c0m");
echo $str;
?>

Tips for dynamically creating new functions in golang functions Tips for dynamically creating new functions in golang functions Apr 25, 2024 pm 02:39 PM

Go language provides two dynamic function creation technologies: closure and reflection. closures allow access to variables within the closure scope, and reflection can create new functions using the FuncOf function. These technologies are useful in customizing HTTP routers, implementing highly customizable systems, and building pluggable components.

Considerations for parameter order in C++ function naming Considerations for parameter order in C++ function naming Apr 24, 2024 pm 04:21 PM

In C++ function naming, it is crucial to consider parameter order to improve readability, reduce errors, and facilitate refactoring. Common parameter order conventions include: action-object, object-action, semantic meaning, and standard library compliance. The optimal order depends on the purpose of the function, parameter types, potential confusion, and language conventions.

What are the benefits of C++ functions returning reference types? What are the benefits of C++ functions returning reference types? Apr 20, 2024 pm 09:12 PM

The benefits of functions returning reference types in C++ include: Performance improvements: Passing by reference avoids object copying, thus saving memory and time. Direct modification: The caller can directly modify the returned reference object without reassigning it. Code simplicity: Passing by reference simplifies the code and requires no additional assignment operations.

What is the difference between custom PHP functions and predefined functions? What is the difference between custom PHP functions and predefined functions? Apr 22, 2024 pm 02:21 PM

The difference between custom PHP functions and predefined functions is: Scope: Custom functions are limited to the scope of their definition, while predefined functions are accessible throughout the script. How to define: Custom functions are defined using the function keyword, while predefined functions are defined by the PHP kernel. Parameter passing: Custom functions receive parameters, while predefined functions may not require parameters. Extensibility: Custom functions can be created as needed, while predefined functions are built-in and cannot be modified.

C++ Function Exception Advanced: Customized Error Handling C++ Function Exception Advanced: Customized Error Handling May 01, 2024 pm 06:39 PM

Exception handling in C++ can be enhanced through custom exception classes that provide specific error messages, contextual information, and perform custom actions based on the error type. Define an exception class inherited from std::exception to provide specific error information. Use the throw keyword to throw a custom exception. Use dynamic_cast in a try-catch block to convert the caught exception to a custom exception type. In the actual case, the open_file function throws a FileNotFoundException exception. Catching and handling the exception can provide a more specific error message.
