    if ($content = getData('LED'))
    {
        return $content;
    }

需要在数组上线直到内容不为空!怎么样？惹坏英语

    public static function assign($name, $value)
    {
        $this->params[] = array($name => $value);
    }

    public static function draw()
    {
        return $this->params;
    }
}


<?php
    $test = Templater::assign('key', 'value')->draw();
    print_r($test);

我需要函数"assign"是静态的,但$ params对于整个类来说很常见..但是这段代码不起作用.

Fatal error: Using $this when not in object context

有任何想法吗？

$a = array('matches' => 
        array(
            '5' => array('weight' => 6),
            '15' => array('weight' => 6),
        )
    );

    $b = array('matches' => 
        array(
            '25' => array('weight' => 6),
            '35' => array('weight' => 6),
        )
    );

    $merge = array_merge($a, $b);

    print_r($merge);

这个脚本的结果是

Array
(
    [matches] => Array
        (
            [25] => Array
                (
                    [weight] => 6
                )

            [35] => Array
                (
                    [weight] => 6
                )

        )

)

但为什么？

我想结果是这样的:

Array
(
    [matches] => Array
        (
            [5] => Array
                (
                    [weight] => 6
                ) …

var ddd = Math.random() * 16;    
console.log((ddd & 3 | 8).toString(16));

请帮帮我.我不明白这个运算符(|和&)的工作原理以及为什么这段代码会返回符号？

我的元素在一个点周围盘旋. 的jsfiddle

HTML

<div class="center-dot">
    <div class="dot"></div>
    <div class="one"></div>
    <div class="two"></div>
</div>

CSS:

.center-dot {position:relative;top:200px;left:200px;}
.dot {width:3px;height:3px;background:blue;}
.one {width:40px;height:40px;border-radius:40px;background:red;position:absolute;}
.two {width:40px;height:40px;border-radius:40px;background:green;position:absolute;}

JS:

var one = $('.one'),
    two = $('.two');

var one_start = 0,
    two_start = 0;

setInterval(function(){
    ++one_start;
    var one_css = {
        'left': Math.sin(one_start * 0.0010) * 100 ,
        'top': Math.cos(one_start * 0.0010) * 100
    }
    one.css(one_css);

    ++two_start;
    var two_css = {
        'left': Math.sin(two_start * 0.0025) * 200 ,
        'top': Math.cos(two_start * 0.0025) * 200
    }
    two.css(two_css);
}, 1);

但他并没有完全这样做,而是喜欢它的曲折. …

<if a == 5 && b < 4>
    one
<else>
    <if a != 5>
        two
    <else>
        <if a == 5 || $b == 5>
            three
         </if>
     </if>
</if>

我怎么能从它得到一些变量:

[0] = "a == 5 && b < 4"
[1] = "one"
[2] = "a != 5"
[3] = "two"
[4] = "a == 5 || $b == 5"
[5] = "three"

或者您如何建议在模板中创建条件？

我使用Zend Gdata库搜索视频Youtube API.如果我发出错误请求,那么zend异常..示例:

但我不希望我的网站的用户看到这个错误...我需要捕获此错误并导致没有异常,只是想得到错误的文本..我该怎么办？
