我是Ubuntu的新手我想使用PECL id3包,所以我从Windows转移到了Ubuntu.

我安装了php5,apache2,libcurl,php5-dev,php-pear但是当我尝试安装php_http扩展时它出错了.它要求zlib和libcurl,我只需按回车键选择默认值,然后在最后发生错误:

任何人都可以告诉我如何替换除了下划线和句号符号之外的字符串中的所有特殊字符.而且我一直在努力了解如何使这个替换模式阅读PHP手册及其如此令人困惑的初学者喜欢我是否有任何其他文档或教程,这对初学者来说很容易,所以我不必发布这样的另一个问题,每次我想要使用这个功能时给你的人带来麻烦？

preg_replace('/[^a-zA-Z0-9]/', '', $string);

这是我所拥有的它取代所有特殊字符,但我想除了_和 ..

这是我的代码,但它说replace is not declared in this scope这不是正确的语法？

#include<iostream>                                                                          
#include<string>                                                                            


using namespace std;                                                                        

int  main ()                                                                                
{                                                                                           
  string string_to_edit;                                                                    
  cout<<"Enter a string to replace all the vowels:"<<endl;                                  
  cin>>string_to_edit;                                                                      
  string output_string=replace(string_to_edit.begin(),string_to_edit.end(),"a","x");               
  cout<<output_string<<endl;                                                                
  return 0;                                                                                 
} 

我一直在尝试这个,现在仍然无法找到答案,当我尝试 sudo pecl install id3这个错误发生

downloading id3-0.2.tgz ...

Cannot find config.m4.
Make sure that you run '/usr/bin/phpize' in the top level source directory of the module

If the command failed with 'phpize: not found' then you need to install php5-dev     packageYou can do it by running 'apt-get install php5-dev' as a root userERROR: `phpize' failed

请帮忙 !!!我已经安装了php5-dev.

即时通讯使用以下代码来获取客户端IP当我尝试通过它获取我的IP它说103.245.196.41但我的实际IP是10.100.210.5.我的代码:

    $ip=$_SERVER['HTTP_CLIENT_IP'];
} elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) {
