作用:取得随机字符串

参数:

2、(int)$mode = 0 #随机字符类型,0为大小写英文和数字,1为数字,2为小写子木,3为大写字母,4为大小写字母,5为大写字母和数字,6为小写字母和数字

返回:取得的字符串

使用:

用 PHP 动态创建 Flash 动画 (Rate:) (转)

作者: unknow 发布时间: 2002-7-11 文章类型: 转载 阅读次数: 124次 来自: unknow

Macromedia 公司出品的 Flash 动画软件现已经成为Web页面上非常流行的表现工具,网站开发者利用它引起浏览者的兴趣。然而不幸的是,仅仅使用ActionScript创建动画受到很大的限制,Macromedia已经宣布,打算放弃Flash Generator产品,转而采用支持Flash MX的Cold Fusion,我们的网站将向何处去呢?现在,我们可以利用Ming PHP库来轻松地动态创建Flash动画,并且和我们的代码无缝集成。我们可以根据数据库里的数据创建出各种不同效果的动画。

Ming 动画库最初出现在PHP4.05版本里,替代了以前版本的LibSwf模块。Ming 库采用C编写,支持多种语言,下面先看一下如何利用PHP来制作动画。该库使用简单,和 PHP 紧密集成,但是,该库仍然处于实验阶段,目前的版本是0.2a,在线的教程、例子、和帮助手册可以让我们方便地学习,Ming里的函数组织的很有条理,方便PHP和Flash开发者查找。使用 PHP和Ming库,不但让我们的网站有华丽的装饰,而且可以减少开发Flash动画的费用和繁复的劳动。

使用Ming库有两种方式,我们可以内嵌到PHP里(对Unix平台而言),也可以把它作为一个PHP模块来运行,里面的函数支持所有的平台,使用时也无需实例化。如果我们把Ming库作为PHP模块来运行的话,我们必须明确地调用Ming库,和使用其他模块一样,然后使用该库里的函数。由于使用前必须先加载模块,与把Ming作为内部函数编译的方式相比,要有一点性能的下降。

Ming库是完全免费的,我们可以到创作者的网站下载,地址是:[url]http://www.opaque.net/ming/[/url],该网站....php.net/ming。

一旦我们正确安装和配置了Ming库,我们可以创建一个PHP对象,从PHP里调用Ming的函数,通过调用函数和属性,就可以定义我们的动画了。在PHP模块里有13个对象,提供了Flash的一些功能,也有几个命令可以来控制发行时的参数设定。下面就看看如何利用它来创建动画。

使用Macromedia Flash创建SWF格式的动画,我们先创建一些符号,Flash有三种类型的符号:图形、动画剪辑、按钮。一旦我们创建了这些符号,我们就可以把它们复制到场景里,每一个拷贝称为一个实例,可以放任意多的实例到我们的场景里。接下来就可以定义这些对象的行为了,也就是定义动作和运动轨迹,也可以定义动画的参数,如尺寸大小和背景颜色,如果需要,可以保存成.SWF文件。

利用PHP的Ming库创建Flash动画,和Macromedia Flash一样,必须先创建一些符号,这些符号就是PHP对象的实例,然后定义这些对象在动画场景里的位置和相互关系,接着定义对象在每一帧里的动作,最后定义动画自己。我们可以直接把SWF直接输出到浏览器,也可以保存成SWF格式的文件,以备后用。Flash的优点就是图形化的用户接口,利用Ming库不但可以更加简单的控制对象,而且具有无限的扩展性和再用性。

下面我们就用一个完整的例子来看看如何使用Ming库:

/* 首先创建一个符号,并填充颜色 */

$square = new SWFShape();

$sqfill = $square->addFill(0, 0, 0xff);

$square->setRightFill($sqfill);

$square->movePenTo(-250,-250);

$square->drawLineTo(250,-250);

$square->drawLineTo(250,250);

$square->drawLineTo(-250,250);

$square->drawLineTo(-250,-250);

/* 在动画剪辑里使用上面的符号,并添加一些脚本 */

$sqclip = new SWFSprite();

$i = $sqclip->add($square);

$i->setDepth(1);

$sqclip->setframes(25);

$sqclip->add(new SWFAction("stop();"));

$sqclip->nextFrame();

$sqclip->add(new SWFAction("play();"));

for($n=0; $n<24; $n++) {

$i->rotate(-15);

$sqclip->nextFrame();

}

/* 下面创建按钮 */

function rect($r, $g, $b) {

$s = new SWFShape();

$s->setRightFill($s->addFill($r, $g, $b));

$s->drawLine(500,0);

$s->drawLine(0,500);

$s->drawLine(-500,0);

$s->drawLine(0,-500);

return $s;

}

$b = new SWFButton();

$b->addShape(rect(0xff, 0, 0), SWFBUTTON_UP | SWFBUTTON_HIT);

$b->addShape(rect(0, 0xff, 0), SWFBUTTON_OVER);

$b->addShape(rect(0, 0, 0xff), SWFBUTTON_DOWN);

$b->addAction(new SWFAction("setTarget('/box'); gotoandplay(2);"), SWFBUTTON_MOUSEDOWN);

/* 下面创建动画,并添加上面的符号和按钮 */

$m = new SWFMovie();

$m->setDimension(4000,3000);

$i = $m->add($sqclip);

$i->setDepth(3);

$i->moveTo(1650, 400);

$i->setName("box");

$i = $m->add($b);

$i->setDepth(2);

$i->moveTo(1400,900);

/* 最后,我们把它输出到浏览器 */

header('Content-type: application/x-shockwave-flash');

$m->output();

?>
