查看工作和使用压缩器 DEMO

README.RU.md 俄语说明

phpCompressor - 主要任务是压缩PHP代码，它也可以用作简单的PHP混淆器。压缩器通过删除空格、代码注释、函数中局部变量的名称缩写、属性类（变量）的名称缩写、类方法的名称缩写来压缩代码。

压缩设置

• 函数中局部变量名的压缩
• 类属性（变量）的名称压缩
• 类方法的名称压缩
• 删除空格、注释和换行符

名称缩写的原则

使用别名缩写名称，这些别名根据名称的使用频率形成。

例如：名称 'data' 在代码中使用了98次，'options' - 70次，'values' - 68次等。结果将是

• 'data' => 'a'
• 'options' => 'b'
• 'values' => 'c'
• '...' => 'd...aa'
• 'rare_name' => 'ab'
• .....

安装

要安装，请使用composer composer

php composer.phar require genasyst/php-compressor

使用示例

<?php

$compressor = new \Genasyst\phpCompressor\Compressor();

$code = 'echo $data;..... ';
/* Setting the code with the opening tag <?php first */
$compressor->setContentByCode('<?php '.$code);

/ * Install code from php file */
$file_path = __DIR__ .'/ExampleTestEcho.php';
$compressor->setContentByFile($file_path);


/**
 * SETTINGS
 *
 * Set reduction of local variables
 */
$compressor->compressLocalVariablesName();

/**
 * Set the reduction of class properties
 */
$compressor->compressObjectsVariablesName();

/**
 * Setting abbreviations for method names
 */
$compressor->compressObjectsMethodsName();


/**
 * WITH THE EXCEPTION OF COMPRESSION NAMES
 *
 *

 */
$compressor->setExcludeNames(

    ['not_compress_local' => 'not_compress_local']

/**

 */
$compressor->setExcludeNames(

    ['thisMethodNameNotCompressed' => 'thisMethodNameNotCompressed']
);
