安装pear 的命令如下：

$ wget http://pear.php.net/go-pear.phar

$ php go-pear.phar

pear 安装成功！

下面用 pear 来安装phpunit

pear channel-discover pear.phpunit.de

pear channel-discover components.ez.no

pear channel-discover pear.symfony-project.com

pear upgrade-all

pear install phpunit/PHPUnit

在安装的过程中可能会出现依赖包，按照提示信息进行安装。

如:yum install php-dom -y等

例子：a.php

<?php

class StackTest extends PHPUnit_Framework_TestCase

{

    public function testPushAndPop()

    {

        $stack = array();

        $this->assertEquals(0, count($stack));

        array_push($stack, ‘foo‘);

        $this->assertEquals(‘foo‘, $stack[count($stack)-1]);

        $this->assertEquals(1, count($stack));

        $this->assertEquals(‘foo‘, array_pop($stack));

        $this->assertEquals(0, count($stack));

    }

?>

phpunit a.php 看到OK，表示成功

基本过程结束

用pear来安装phpunit
