无意间想到这个问题,如何用php来实现git diff,如果实现了这个功能,岂不是能够使用php对在线编辑文件的功能做更进一步的优化和提升?
查了一下还真有这样的库,话不多说,开始执行
composer require --dev sebastian/diff得到结果

1 package you are using is looking for funding.
Use the `composer fund` command to find out more!好,安装成功,创建index.php如下
<?php
include("./vendor/autoload.php");
use SebastianBergmann\Diff\Differ;
use SebastianBergmann\Diff\Output\UnifiedDiffOutputBuilder;
$builder = new UnifiedDiffOutputBuilder(
"--- Original\n+++ New\n", // custom header
true // do not add line numbers to the diff
);
$differ = new Differ($builder);
$before_string = file_get_contents("functions.php");
$after_string = file_get_contents("functions.php-new");
$diff_value = $differ->diff($before_string, $after_string);
echo $diff_value;好,然后创建两个文件用来代表我们修改过文件的内容,修改之前的文件叫 functions.php 内容是
<?php
function get_rand_id ($id = 0) {
static $id;
if ($id) {
return $id;
}
$id = rand(1, 1000);
$id += 1000;
return $id;
}修改之后的文件叫 functions.php-new 内容是
<?php
function get_random_id (int $id = 0) {
static $id;
if (!$id) {
$id = rand(1, 1000);
$id = $id * $id;
}
return $id;
}执行一下看看
php index.php &> diff.patch得到结果
--- Original
+++ New
@@ -1,12 +1,11 @@
<?php
-function get_rand_id ($id = 0) {
+function get_random_id (int $id = 0) {
static $id;
- if ($id) {
- return $id;
+ if (!$id) {
+ $id = rand(1, 1000);
+ $id = $id * $id;
}
- $id = rand(1, 1000);
- $id += 1000;
return $id;
}那这样的结果呢也能作为patch查看,要怎么有更好的查看方式呢?
我们可以在vscode编辑器里面安装一个叫做 Diff Viewer 的插件 点击这里
安装完毕, 打开这个 diff.patch 文件后是这样的
怎么样,是不是很不错,有点像 git 的感觉了,哈哈哈
