How to enable runkit PHP extension with lampp

Lampp的php extension目录如下：

[root@www no-debug-non-zts-20060613]# pwd

/opt/lampp/lib/php/extensions/no-debug-non-zts-20060613

[root@www no-debug-non-zts-20060613]# ll

新加载了这个runkit.so到php.ini里。

runkit

• Pear install runkit-0.9.tgz出错

  /usr/local/src/runkit-0.9/runkit_import.c: In function ‘php_runkit_import_class_props’:
  /usr/local/src/runkit-0.9/runkit_import.c:230: warning: passing argument 2 of
  ‘zend_unmangle_property_name’ makes integer from pointer without a cast
  /usr/local/src/runkit-0.9/runkit_import.c:230: error: too few arguments to function
  ‘zend_unmangle_property_name’ make: *** [runkit_import.lo] Error 1
  

• 查找网上资料，找到http://kb.bobcares.com/?View=entry&EntryID=827

  原来是有bug,fix一下：

Fix is as follows

Edit the file /usr/local/src/runkit-0.9/runkit_import.c and change the following line

zend_unmangle_property_name(key, &cname, &pname);

To:

zend_unmangle_property_name(key, key_len, &cname, &pname);

Again continue with the installation steps.

#cd /usr/local/src/runkit-0.9
#make
#make install

Edit the loaded PHP configuration file ( here /usr/local/lib/php.ini ) and add the following line.

extension=runkit.so

You can verify the runkit extension by

root@host[/usr/local/src/runkit-0.9]# php -i | grep -i runkit
runkit
runkit support => enabled

Yii:CI的又一对手出现了

Yes, it is Yii — a high-performance component-based PHP framework best for developing large-scale Web applications. Yii comes with a full stack of features, including MVC, DAO/ActiveRecord, I18N/L10N, caching, jQuery-based AJAX support, authentication and role-based access control, scaffolding, input validation, widgets, events, theming, Web services, and so on. Written in strict OOP, Yii is easy to use and is extremely flexible and extensible.

又将是一个流行框架，吸收了很多现在流行ROR技术和快速开发的工具。

Writing hadoop mapreduce program in php

最近在作营销效果分析的需求，需要处理大量网页访问日志（千万级PV以上），HADOOP在这方面正好有用武之地。PHP是一个简单实用的语言，我 很喜欢。影响我最大的计算机语言，除了LISP，就是PHP了(python这类的脚本语言学起来也很舒服)。于是我准备在我的D630本本上玩玩php in hadoop.

• 先下载VMWARE PLAYER：

The virtual machine image is designed to be used with the free VMware Player.

VMware Player 2.5.1

Latest Version: 2.5.1 | 2008/11/21 | Build: 126130

http://www.vmware.com/download/player/

• 下载hadoopvm

Download the VMWare image here:

http://code.google.com/intl/zh-CN/edu/parallel/tools/hadoopvm/index.html

启动hadoopvm

• 去掉原来的源；然后加入源,否则feisty不能升级包；：

vi /etc/apt/sources.list

deb http://ubuntu.cn99.com/ubuntu/ feisty main restricted universe multiverse

deb http://ubuntu.cn99.com/ubuntu/ feisty-security main restricted universe multiverse

deb http://ubuntu.cn99.com/ubuntu/ feisty-updates main restricted universe multiverse

deb http://ubuntu.cn99.com/ubuntu/ feisty-proposed main restricted universe multiverse

deb http://ubuntu.cn99.com/ubuntu/ feisty-backports main restricted universe multiverse

deb-src http://ubuntu.cn99.com/ubuntu/ feisty main restricted universe multiverse

deb-src http://ubuntu.cn99.com/ubuntu/ feisty-security main restricted universe multiverse

deb-src http://ubuntu.cn99.com/ubuntu/ feisty-updates main restricted universe multiverse

deb-src http://ubuntu.cn99.com/ubuntu/ feisty-proposed main restricted universe multiverse

• 执行apt-get update 更新包；
• 确认当前用户是ROOT

Login as user ‘root’ (password ‘root’),

• run ‘apt-get install php5-cli’ to install PHP5.
• Now switch to user ‘guest’ (password ‘guest’).

• php -v查看当前PHP是否安装好

(图1)

• 生成两个程序：mapper.php和reducer.php

#!/usr/bin/php

<?

$word2count = array();

// input comes from STDIN (standard input)

while (($line = fgets(STDIN)) !== false) {

// remove leading and trailing whitespace and lowercase

$line = strtolower(trim($line));

// split the line into words while removing any empty string

$words = preg_split(’/\W/’, $line, 0, PREG_SPLIT_NO_EMPTY);

// increase counters

foreach ($words as $word) {

$word2count[$word] += 1;

}

}

// write the results to STDOUT (standard output)

// what we output here will be the input for the

// Reduce step, i.e. the input for reducer.py

foreach ($word2count as $word => $count) {

// tab-delimited

echo $word, chr(9), $count, PHP_EOL;

}

?>

reducer.php

#!/usr/bin/php

<?

$word2count = array();

// input comes from STDIN

while (($line = fgets(STDIN)) !== false) {

// remove leading and trailing whitespace

$line = trim($line);

// parse the input we got from mapper.php

list($word, $count) = explode(chr(9), $line);

// convert count (currently a string) to int

$count = intval($count);

// sum counts

if ($count > 0) $word2count[$word] += $count;

}

// sort the words lexigraphically

//

// this set is NOT required, we just do it so that our

// final output will look more like the official Hadoop

// word count examples

ksort($word2count);

// write the results to STDOUT (standard output)

foreach ($word2count as $word => $count) {

echo $word, chr(9), $count, PHP_EOL;

}

?>

• chmod +x /home/guest/mapper.php /home/guest/reducer.php
• 准备程序所需要的作为输入的文本文件的目录，

mkdir /tmp/countfile

• 下载远程的两个TXT文本作为输入

wget http://pge.rastko.net/dirs/2/0/4/1/20417/20417-8.txt

wget http://www.pg-news.org/nl_archives/2009/pgmonthly_2009_01_21.txt

• 把文件放入HADOOP 的DFS中

cd /home/guest/hadoop/

bin/hadoop dfs -copyFromLocal /tmp/countfile countfile

• 执行php程序处理这些文本

bin/hadoop jar contrib/hadoop-streaming.jar -mapper /home/guest/mapper.php -reducer /home/guest/reducer.php -input countfile/* -output countfile-output

• 查看输出的结果

bin/hadoop dfs -ls countfile-output

bin/hadoop dfs -cat countfile-output/part-00000

PHP性能调优好工具XDEBUG+WINCACHEGRIND

下载对应PHP版本的xdebug: [url]http://www.xdebug.org[/url] 下载wincachegrind:[url]http://sourceforge.net/projects/wincachegrind/[/url] 配置php.ini: 我的是PHP5.2.2使用5.2.1的xdebug.dll extension=php_xdebug-2.0.0rc4-5.2.1.dll [Xdebug] xdebug.profiler_enable=on xdebug.trace_output_dir=”d:/APMXE5/xdebug” xdebug.profiler_output_dir=”d:/APMXE5/xdebug” 在d:/APMXE5/xdebug会生成cachegrind.out.2336这样的文件。使用wincachegrid打开就可以看到哪些方法调用占的时间多。 在LINUX也有相应的软件读取cachegrind.out.2336这样的文件。上次看到Rambus在作报靠使用的MAC机器上的一个工具，也很好看。 Functionality The Xdebug extension helps you debugging your script by providing a lot of valuable debug information. The debug information that Xdebug can provide includes the following: stack and function traces in error messages with: full parameter display for user defined functions function name, file name and line indications support for member functions memory allocation protection for infinite recursions Xdebug also provides: profiling information for PHP scripts script execution analysis capabilities to debug your scripts interactively with a debug client
