我有以下代码,
<?php
class Templater
{
static $params = array();
public static function assign($name, $value)
{
self::$params[] = array($name => $value);
}
public static function draw()
{
self::$params;
}
}
$test = Templater::assign('key', 'value');
$test = Templater::draw();
print_r($test);
如何更改此脚本以便我可以使用它？
$test = Templater::assign('key', 'value')->assign('key2', 'value2')->draw();
print_r($test);
function query($url, $pfields = 0, $cookie = 0)
{
curl_setopt($ch, CURLOPT_HEADER, 1);
if (!empty($pfields))
{
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $pfields);
}
if (!empty($cookie))
{
curl_setopt($ch, CURLOPT_COOKIE, $cookie);
}
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_ENCODING,'gzip');
if (!$login)
{
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
}
$content = curl_exec($ch);
return $content;
}
$cookie = 'sessionID=3864cab58412ec567b634db3c317898;OAGEO=RU%7C%7C%7C%7C%7C%7C%7C%7C%7C%7C;';
$p = '++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++';
$post = 'clientid=23&campaignid=52&bannerid=111&appendsave=1&appendtype=0&append=' . urlencode($p) . '&submitbutton=';
echo query('http://example.com/in.php', $post, $cookie);
此代码返回417错误(但是$ p不是使用urlencode但是IS OK但是+(加)更改为""(空格)
Sooooorry因为我非常糟糕的英语
<?php
$xs = eval("if ('1' == '0')
echo 'never';
else
echo 'always';");
//echo $xs;
此代码返回'always'但我不想要它.我需要在其他地方采用这个变量.
抱歉英文不好.
编辑:
PEOPLE !!!!!!!这个示例代码.我知道在这种情况下不需要eval(),但我的其他项目中的代码将是.我需要将eval()返回的内容输入变量."
在我的500万条记录的数据库中.表的结构:
CREATE TABLE IF NOT EXISTS `music` (
`id` int(50) NOT NULL auto_increment,
`artistname` varchar(50) NOT NULL,
`songname` varchar(50) NOT NULL,
`duration` varchar(6) NOT NULL,
`url` varchar(255) NOT NULL,
`server` int(5) NOT NULL,
PRIMARY KEY (`id`),
KEY `artistname` (`artistname`),
KEY `songname` (`songname`),
KEY `url` (`url`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 ;
如何优化表格然后搜索"artistname"和"songname"字段？
抱歉英文不好.来自俄罗斯的爱:-D

添加

我如何以绝对div为中心？
<div class="photoWindow">min width 600 px, absolute</div>
jQuery的
var widthScreen = $(window).width();
$('.photoWindow').css({'margin-left': widthScreen / 2 - widthScreen, 'left':'50%'});
但是,这并不是div的中心.
