diff

Sebastian/diff

PHP的DIFF实现将PHPUNIT分为独立组件。

安装

您可以使用Composer将此库作为本地，每项项目依赖性添加到您的项目中：

composer require sebastian/diff

如果您在开发过程中只需要此库，例如，要运行项目的测试套件，则应将其添加为开发时间依赖性：

composer require --dev sebastian/diff

用法

生成差异

Differ类可用于生成两个字符串之间差异的文本表示：

 <？php声明（strict_types = 1）;使用sebastianbergmanndiffdiffer;使用sebastianbergmanndiffOutputunifutunifieddiffOutputbuilder; $ difly; $ divel = new drive = new dislift dislift dislifate dislifate dislifate dislifate distric（新的unieddiffOutputbuilder）;

打印$ differ-> diff（'foo'，'bar'）;

上面的代码得出以下输出：

 ---原始+++ new @@ @@ @@- foo+bar

上面示例中使用的UnifiedDiffOutputBuilder以“统一diff”格式生成输出，例如，phpunit使用。

StrictUnifiedDiffOutputBuilder以Hunks的形式生成“严格统一差异”格式的输出，类似于diff -u ，并且与patch或git apply兼容。

DiffOnlyOutputBuilder生成仅包含不同行的输出。

如果这三个输出构建器都不匹配您的用例，则可以实现DiffOutputBuilderInterface来生成自定义输出。

解析差异

Parser类可用于将统一的差异解析为对象图：

 use SebastianBergmannDiffParser;use SebastianBergmannGit;$git = new Git('/usr/local/src/money');$diff = $git->getDiff(  '948a1a07768d8edd10dcefa8315c1cbeffb31833', 'C07A373D2399F3E686234C4F7F088D635EB9641B'）; $ PARSER = new Parser; print_r; print_r（$ parser-> parse（$ diff））;

上面的代码得出以下输出：

注意：如果块大小为0行，即，即getStartRange()或getEndRange()返回0， getStart()或getEnd()返回的行数比一个人低一个。这是插入或删除块的行号；在所有其他情况下，它给出了替换线范围的第一行号。
