diff

Sebastian/diff

PHP的DIFF實現將PHPUNIT分為獨立組件。

安裝

您可以使用Composer將此庫作為本地，每項項目依賴性添加到您的項目中：

composer require sebastian/diff

如果您在開發過程中只需要此庫，例如，要運行項目的測試套件，則應將其添加為開發時間依賴性：

composer require --dev sebastian/diff

用法

生成差異

Differ類可用於生成兩個字符串之間差異的文本表示：

 <？php聲明（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'）;

上面的代碼得出以下輸出：

 ---原始+++ new @@ @@ @@- foo+bar

上面示例中使用的UnifiedDiffOutputBuilder以“統一diff”格式生成輸出，例如，phpunit使用。

StrictUnifiedDiffOutputBuilder以Hunks的形式生成“嚴格統一差異”格式的輸出，類似於diff -u ，並且與patch或git apply兼容。

DiffOnlyOutputBuilder生成僅包含不同行的輸出。

如果這三個輸出構建器都不匹配您的用例，則可以實現DiffOutputBuilderInterface來生成自定義輸出。

解析差異

Parser類可用於將統一的差異解析為對像圖：

使用sebastianbergmanndiffparser;使用sebastianbergmanngit; $ git = new Git（'/usr/locar/local/src/money'）; $ diff = $ gitdiff（'948A1A077768D8EDDDCEFA8315C15C1CBEFFB333E33E33E33EN3EN3ER.N.948A1A077768D8DD8DD8DD8DDD83EN3EN3EN3ER 4F7F088D635EB9641B'）; $ parser = new Parser; print_r（ print_r（ $ PARSER-> PARSE（$ diff））;

上面的代碼得出以下輸出：

注意：如果塊大小為0行，即，即getStartRange()或getEndRange()返回0， getStart()或getEnd()返回的行數比一個人低一個。這是插入或刪除塊的行號；在所有其他情況下，它給出了替換線範圍的第一行號。
