如何$_POST使用值将值传递给页面cURL？

所以我正在重构我的代码来实现更多的OOP.我设置了一个类来保存页面属性.

class PageAtrributes 
{
  private $db_connection;
  private $page_title;

    public function __construct($db_connection) 
    {
        $this->db_connection = $db_connection;
        $this->page_title = '';
    }

    public function get_page_title()
    {
        return $this->page_title;
    }

    public function set_page_title($page_title)
    {
        $this->page_title = $page_title;
    }
}

稍后我会调用set_page_title()函数

function page_properties($objPortal) {    
    $objPage->set_page_title($myrow['title']);
}

当我这样做时,我收到错误消息:

在非对象上调用成员函数set_page_title()

那我错过了什么？

我有一台Apache服务器,其中一个访问日志文件高达600MB.这使搜索文件或解析文件变得非常困难.
Apache可以使用哪些软件或模块来制作我的访问文件的每日副本,以使其更易于管理？

所以我们的SQL Server 2000给了我错误,"数据库的日志文件已满.备份数据库的事务日志以释放一些日志空间."

如何在不删除日志的情况下修复此问题,就像其他网站提到的一样？

附加信息:启用AutoGrowth启用增长10%,限制为40MB.

这看起来很简单,但我从jqGrid代码中得到这个神秘的错误,说"元素不是表".这是代码:

var grid_data = [ {id:"1",invdate:"2007-10-01",name:"test",note:"note",amount:"200.00",tax:"10.00",total:"210.00"}, {id:"1",invdate:"2010-05-24",name:"test",note:"note",tax:"10.00",total:"2111.00"} , {id:"2",invdate:"2010-05-25",name:"test2",note:"note2",tax:"20.00",total:"320.00"}, {id:"3",invdate:"2007-09-01",name:"test3",note:"note3",tax:"30.00",total:"430.00"}, {id:"4",invdate:"2007-10-04",name:"test",note:"note",tax:"10.00",total:"210.00"}, {id:"5",invdate:"2007-10-05",name:"test2",note:"note2",tax:"20.00",total:"320.00"}, {id:"6",invdate:"2007-09-06",name:"test3",note:"note3",tax:"30.00",total:"430.00"}, {id:"7",invdate:"2007-10-04",name:"test",note:"note",tax:"10.00",total:"210.00"}, {id:"8",invdate:"2007-10-03",name:"test2",note:"note2",amount:"300.00",tax:"21.00",total:"320.00"}, {id:"9",invdate:"2007-09-01",name:"test3",note:"note3",amount:"400.00",tax:"30.00",total:"430.00"}, {id:"11",invdate:"2007-10-01",name:"test",note:"note",amount:"200.00",tax:"10.00",total:"210.00"}, {id:"12",invdate:"2007-10-02",name:"test2",note:"note2",amount:"300.00",tax:"20.00",total:"320.00"}, {id:"13",invdate:"2007-09-01",name:"test3",note:"note3",amount:"400.00",tax:"30.00",total:"430.00"}, {id:"14",invdate:"2007-10-04",name:"test",note:"note",amount:"200.00",tax:"10.00",total:"210.00"}, {id:"15",invdate:"2007-10-05",name:"test2",note:"note2",amount:"300.00",tax:"20.00",total:"320.00"}, {id:"16",invdate:"2007-09-06",name:"test3",note:"note3",amount:"400.00",tax:"30.00",total:"430.00"}, {id:"17",invdate:"2007-10-04",name:"test",note:"note",amount:"200.00",tax:"10.00",total:"210.00"}, {id:"18",invdate:"2007-10-03",name:"test2",note:"note2",amount:"300.00",tax:"20.00",total:"320.00"}, {id:"19",invdate:"2007-09-01",name:"test3",note:"note3",amount:"400.00",tax:"30.00",total:"430.00"}, {id:"21",invdate:"2007-10-01",name:"test",note:"note",amount:"200.00",tax:"10.00",total:"210.00"}, {id:"22",invdate:"2007-10-02",name:"test2",note:"note2",amount:"300.00",tax:"20.00",total:"320.00"}, {id:"23",invdate:"2007-09-01",name:"test3",note:"note3",amount:"400.00",tax:"30.00",total:"430.00"}, {id:"24",invdate:"2007-10-04",name:"test",note:"note",amount:"200.00",tax:"10.00",total:"210.00"}, {id:"25",invdate:"2007-10-05",name:"test2",note:"note2",amount:"300.00",tax:"20.00",total:"320.00"}, {id:"26",invdate:"2007-09-06",name:"test3",note:"note3",amount:"400.00",tax:"30.00",total:"430.00"}, {id:"27",invdate:"2007-10-04",name:"test",note:"note",amount:"200.00",tax:"10.00",total:"210.00"}, {id:"28",invdate:"2007-10-03",name:"test2",note:"note2",amount:"300.00",tax:"20.00",total:"320.00"}, {id:"29",invdate:"2007-09-01",name:"test3",note:"note3",amount:"400.00",tax:"30.00",total:"430.00"}  ];

我正在使用PHP和xpath从API调用解析XML结果.

 $dom = new DOMDocument();
 $dom->loadXML($response->getBody());

 $xpath = new DOMXPath($dom);
 $xpath->registerNamespace("a", "http://www.example.com");

 $hrefs = $xpath->query('//a:Books/text()', $dom);

 for ($i = 0; $i < $hrefs->length; $i++) {
      $arrBookTitle[$i] = $hrefs->item($i)->data;
 }

 $hrefs = $xpath->query('//a:Books', $dom);

 for ($i = 0; $i < $hrefs->length; $i++) {
      $arrBookDewey[$i] = $hrefs->item($i)->getAttribute('DeweyDecimal');
 }

这有效,但有一种方法我可以从一个查询访问文本和属性？如果是这样,一旦执行查询,您如何获得这些项目？

在我的Wordpress博客上,我使用wp-sytax插件来格式化代码片段.

在HTML视图中,我有以下代码:

<pre lang="c">
#include<stdio.h>
</pre>

但在常规视图中显示:

#include<stdio.h>

我怎么能#include<stdio.h>在输入时出现？

所以我写了一些perl来解析从Amazon Web Services返回的结果.我正在使用这个XML::Simple包.在大多数情况下,当我拿出一个元素时,一切都有效.但是,我遇到的问题是元素也有属性.然后我得到一个错误,该项目是哈希.

如果我想获得DVD的运行时间,我就是这样做的:我刚刚创建了一个项目来保存这个一次性项目的具体信息.

// XML
<ProductGroup>DVD</ProductGroup>
<RunningTime Units="minutes">90</RunningTime>

// Perl to parse XML

my $item = $xml->XMLin($content, KeyAttr => { Item => 'ASIN'}, ForceArray => ['ASIN']);    

$ProductGroup = $item->{Items}->{Item}->{ItemAttributes}->{ProductGroup};

if(ref($item->{Items}->{Item}->{ItemAttributes}->{RunningTime}) eq 'HASH'){
    $RunningTimeXML = $xml->XMLin($content, KeyAttr => { Item => 'ASIN'}, NoAttr => 1);
    $RunningTime = $RunningTimeXML->{Items}->{Item}->{ItemAttributes}->{RunningTime};
}

有没有办法可以从一个项目访问元素和属性？

有没有办法使用正则表达式搜索twitter api？我需要匹配的表达式是股票名称.

/\$[a-zA-Z]{1,5}/
