CTools工具库

简介

使用 C 语言开发的工具库,工具宗旨:使用最少的代码完成最多的工作 所以我启动了一个工具库的项目,为了让更多的逻辑层的代码减少,增加代码的可靠性。

下载

https://github.com/liqiongfan/ctools

安装

1、下载

git clone https://github.com/liqiongfan/CTools.git

2、Makefile

/usr/path_to_php/bin/phpize
./configure --with-php-config=/usr/path_to_php/bin/php-config

3、编译与安装

make -j
sudo make install -j

4、 启用扩展

echo 'ctools.so' >> /usr/path_to_php/php.ini

一个便于WEB开发的工具库:包含多个组件:线程、进程、数组等,特性正在丰富中

示例

线程

开启一个线程执行耗时操作(asyncRun方法的代码与后面的代码是同时运行):

$thread = new CTool\CThread();

// 开启一个新线程执行耗时操作
// 线程执行完毕后,会自动销毁
$thread->asyncRun( function(){
    echo "I'm doing the job in thread.";
    sleep(5);
} );

// 后续的代码表示是在主线程执行的
echo "I'm the main thread";
sleep(5);

asyncRun方法可以调用多次来生成多个线程:


$thread = new CTool\CThread();

/* 开启第一个线程 */
$thread->asyncRun( function(){
    echo "Yes, one thread." . PHP_EOL;
});

/* 开启第二个线程 */
$thread->asyncRun( function(){
    while(1)
    {
        echo 'Yes, three thread. ' . PHP_EOL;
    }
});

/* 开启第三个线程 */
$thread->asyncRun( function(){
    while(1)
    {
        echo 'Yes, two thread. ' . PHP_EOL;
    } 
});

/*主线程代码*/
echo "I'm the main thread";
sleep(5);

/* 如果后续不需要使用主线程,可以手工调用本函数进行关闭 */
$thread->killMainThread();

进程

生成一个子进程去完成任务,子进程通过线程来完成耗时操作:

$thread = new CTool\CThread();

$process = new CTool\CProcess();

/*生成一个子进程*/
$ret = $process->fork();

if ($ret == 0)
{
	 /* 子进程的第一个子线程 */
    $thread->asyncRun( function(){
        while(1)
        {
            echo 'Yes, three thread. ' . PHP_EOL;
        }
    });
    

	/* 子进程的第二个子线程 */
    $thread->asyncRun( function(){
        while(1)
        {
            echo 'Yes, two thread. ' . PHP_EOL;
        } 
    });
    
    /* 子进程的主线程 */
    echo 'child';
    while(1)
    {
        echo 'Yes. child' . PHP_EOL;
    }
}
else
{
	/* 父进程 */
    echo 'Yes';
    sleep(5);
	
	/* 父进程关闭子进程 */
    $process->kill($ret);
}

【注意】:每个进程与进城之间变量都是一个副本,不能直接通信的,需要借助于IPC机制才行

每次调用fork都会生成一个进程,fork调用的返回值0表示当前是子进程,大于0是父进程(返回值是子进程的id),通过调用kill函数来终止进程

$process = new CTool\CProcess();
$process->kill($pid);

IPC(进程间通信)

使用的IPC手段是共享内存基于Posix,共享内存仅支持 [字符串] 类型

示例:

/* 第一个参数标识的共享内存的ID,不同进程间使用ID即可通信
 * 第二个参数标识共享内存的大小
 */
$shareMemory = new CTool\CIpc\ShareMemory(1, 5*1024);

/* 往共享内存写入数据 */
$shareMemory->writeData("hello");

/* 读取共享内存的数据 */
$shareMemory->readData();

echo PHP_EOL;

数组

1、数组的键与值的合并

$arr = [
    '1' 			=> 'hello', 
    "version" 	=> 'world', 
    2 				=> 323, 
    false,
    true,
    "hello" 		=> false
];

$carray = new CTool\CArray();

print_r($carray->combineKeyValue( $arr ));

输出如下:

Array
(
    [0] => 1hello
    [1] => versionworld
    [2] => 2323
    [3] => 3false
    [4] => 4true
    [5] => hellofalse
)

combineKeyValue方法的第二个参数是 bool 类型,表示是否转换 bool值:

$arr = [
    '1' 			=> 'hello', 
    "version" 	=> 'world', 
    2 				=> 323, 
    false,
    true,
    "hello" 		=> false
];

$carray = new CTool\CArray();

print_r($carray->combineKeyValue( $arr, true ));

输出如下:

Array
(
    [0] => 1hello
    [1] => versionworld
    [2] => 2323
    [3] => 3
    [4] => 41
    [5] => hello
)

2、计算数组某一列的和

$arr = [
	[
		'id' => 1,
		'age' => 25
	],
	[
		'id' => 2,
		'age' => 23
	],
	[
		'id' => 4,
		'age' => 28
	]
];

echo CTool\CArray::columnSum($arr, 'id');

输出如下

7

3、数组合并

$arr = [
    [
        'id' => 2,
        'name' => 'Hello',
        'age' => 3
    ],
    [
        'id' => 3,
        'name' => 'World',
        'age' => 23
    ]
];

$two = [
    [
        't_id' => 2,
        'version' => 'v2.1.1',
        'age' => 3,
    ],
    [
        't_id' => 3,
        'version' => 'v2.1.2',
        'age' => 23
    ],
    [
        't_id' => 4,
        'version' => 'v4.1.2',
        'age' => 25
    ]
];

print_r(CTool\CArray::join($arr, $two, "age", "age"));

输出如下:

Array
(
    [0] => Array
        (
            [id] => 2
            [name] => Hello
            [age] => 3
            [t_id] => 2
            [version] => v2.1.1
            [age1] => 3
        )

    [1] => Array
        (
            [id] => 3
            [name] => World
            [age] => 23
            [t_id] => 3
            [version] => v2.1.2
            [age1] => 23
        )

)

参数过滤

1、过滤参数

echo CTool\CFilter::filter("hello", function($value){
    return 'world' . strtoupper($value) . PHP_EOL;
});

输出如下:

worldHELLO
function changeW($value)
{
    $value[2] = 'T';
    return $value;
}

echo CTool\CFilter::filter("world", 'strtoupper|strtolower|changeW'));

输出如下:

GNU LESSER GENERAL PUBLIC LICENSE Version 3, 29 June 2007 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. This version of the GNU Lesser General Public License incorporates the terms and conditions of version 3 of the GNU General Public License, supplemented by the additional permissions listed below. 0. Additional Definitions. As used herein, "this License" refers to version 3 of the GNU Lesser General Public License, and the "GNU GPL" refers to version 3 of the GNU General Public License. "The Library" refers to a covered work governed by this License, other than an Application or a Combined Work as defined below. An "Application" is any work that makes use of an interface provided by the Library, but which is not otherwise based on the Library. Defining a subclass of a class defined by the Library is deemed a mode of using an interface provided by the Library. A "Combined Work" is a work produced by combining or linking an Application with the Library. The particular version of the Library with which the Combined Work was made is also called the "Linked Version". The "Minimal Corresponding Source" for a Combined Work means the Corresponding Source for the Combined Work, excluding any source code for portions of the Combined Work that, considered in isolation, are based on the Application, and not on the Linked Version. The "Corresponding Application Code" for a Combined Work means the object code and/or source code for the Application, including any data and utility programs needed for reproducing the Combined Work from the Application, but excluding the System Libraries of the Combined Work. 1. Exception to Section 3 of the GNU GPL. You may convey a covered work under sections 3 and 4 of this License without being bound by section 3 of the GNU GPL. 2. Conveying Modified Versions. If you modify a copy of the Library, and, in your modifications, a facility refers to a function or data to be supplied by an Application that uses the facility (other than as an argument passed when the facility is invoked), then you may convey a copy of the modified version: a) under this License, provided that you make a good faith effort to ensure that, in the event an Application does not supply the function or data, the facility still operates, and performs whatever part of its purpose remains meaningful, or b) under the GNU GPL, with none of the additional permissions of this License applicable to that copy. 3. Object Code Incorporating Material from Library Header Files. The object code form of an Application may incorporate material from a header file that is part of the Library. You may convey such object code under terms of your choice, provided that, if the incorporated material is not limited to numerical parameters, data structure layouts and accessors, or small macros, inline functions and templates (ten or fewer lines in length), you do both of the following: a) Give prominent notice with each copy of the object code that the Library is used in it and that the Library and its use are covered by this License. b) Accompany the object code with a copy of the GNU GPL and this license document. 4. Combined Works. You may convey a Combined Work under terms of your choice that, taken together, effectively do not restrict modification of the portions of the Library contained in the Combined Work and reverse engineering for debugging such modifications, if you also do each of the following: a) Give prominent notice with each copy of the Combined Work that the Library is used in it and that the Library and its use are covered by this License. b) Accompany the Combined Work with a copy of the GNU GPL and this license document. c) For a Combined Work that displays copyright notices during execution, include the copyright notice for the Library among these notices, as well as a reference directing the user to the copies of the GNU GPL and this license document. d) Do one of the following: 0) Convey the Minimal Corresponding Source under the terms of this License, and the Corresponding Application Code in a form suitable for, and under terms that permit, the user to recombine or relink the Application with a modified version of the Linked Version to produce a modified Combined Work, in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source. 1) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (a) uses at run time a copy of the Library already present on the user's computer system, and (b) will operate properly with a modified version of the Library that is interface-compatible with the Linked Version. e) Provide Installation Information, but only if you would otherwise be required to provide such information under section 6 of the GNU GPL, and only to the extent that such information is necessary to install and execute a modified version of the Combined Work produced by recombining or relinking the Application with a modified version of the Linked Version. (If you use option 4d0, the Installation Information must accompany the Minimal Corresponding Source and Corresponding Application Code. If you use option 4d1, you must provide the Installation Information in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source.) 5. Combined Libraries. You may place library facilities that are a work based on the Library side by side in a single library together with other library facilities that are not Applications and are not covered by this License, and convey such a combined library under terms of your choice, if you do both of the following: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities, conveyed under the terms of this License. b) Give prominent notice with the combined library that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 6. Revised Versions of the GNU Lesser General Public License. The Free Software Foundation may publish revised and/or new versions of the GNU Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library as you received it specifies that a certain numbered version of the GNU Lesser General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that published version or of any later version published by the Free Software Foundation. If the Library as you received it does not specify a version number of the GNU Lesser General Public License, you may choose any version of the GNU Lesser General Public License ever published by the Free Software Foundation. If the Library as you received it specifies that a proxy can decide whether future versions of the GNU Lesser General Public License shall apply, that proxy's public statement of acceptance of any version is permanent authorization for you to choose that version for the Library.
