折腾：
【未解决】php中用正则过滤html中code中多余span标签
期间，看到：
https://github.com/paquettg/php-html-parser
中提到了，该php的库是建议用composer去安装
对此也就是：
如何才能使用上：
require 'vendor/autoload.php';

如何使用composer
php composer
简介 | Composer 中文文档 | Composer 中文网
但是对于
https://github.com/paquettg/php-html-parser
如何写composer.json没解释
参考
https://github.com/Masterminds/html5-php
和
https://github.com/paquettg/php-html-parser/blob/master/composer.json
{
"require": {
"paquettg/php-html-parser": "2.0.2"
}
}https://packagist.org/packages/paquettg/php-html-parser
不知道对不对
Composer 中文网 / Packagist 中国全量镜像
基本用法 | Composer 中文文档 | Composer 中文网
去安装试试：
curl -sS https://getcomposer.org/installer | php
结果
curl -sS https://getcomposer.org/installer | php <p>All settings correct for using Composer</p><p>Downloading...</p><p>The "https://getcomposer.org/download/1.8.6/composer.phar" file could not be downloaded: SSL: Connection reset by peer</p><p>failed to open stream: HTTP request failed! Retrying...</p><p>^C</p>

全局安装 (on OSX via homebrew)
去试试
➜ useHtmlLibParseEvernoteHtml brew update ^C% ➜ useHtmlLibParseEvernoteHtml ➜ useHtmlLibParseEvernoteHtml brew tap josegonzalez/homebrew-php ==> Tapping josegonzalez/php Cloning into '/usr/local/Homebrew/Library/Taps/josegonzalez/homebrew-php'... remote: Enumerating objects: 6, done. remote: Counting objects: 100% (6/6), done. remote: Compressing objects: 100% (6/6), done. remote: Total 6 (delta 0), reused 2 (delta 0), pack-reused 0 Unpacking objects: 100% (6/6), done.

慢慢下载吧
不过从前面貌似看出是：
直接下载
https://getcomposer.org/download/1.8.6/composer.phar
或：
https://getcomposer.org/download/1.8.5/composer.phar
然后放到PATH的路径中，就可以了的感觉
➜ composer cp composer.phar /usr/local/bin ➜ composer which composer composer not found ➜ composer ll -h total 4352 -rw-r--r--@ 1 crifan staff 1.8M 6 11 21:03 composer.phar ➜ composer ll /usr/local/bin/composer.phar -rw-r--r--@ 1 crifan admin 1.8M 7 23 22:50 /usr/local/bin/composer.phar
但是并不能直接运行
Composer三步曲：安装、使用、发布 – 滴水石穿 – SegmentFault 思否
直接改名为composer就好
➜ composer mv /usr/local/bin/composer.phar /usr/local/bin/composer ➜ composer ll /usr/local/bin/composer -rw-r--r--@ 1 crifan admin 1.8M 7 23 22:50 /usr/local/bin/composer ➜ composer which composer composer not found ➜ composer /usr/local/bin/composer --version zsh: permission denied: /usr/local/bin/composer ➜ composer chmod +x /usr/local/bin/composer ➜ composer ll /usr/local/bin/composer -rwxr-xr-x@ 1 crifan admin 1.8M 7 23 22:50 /usr/local/bin/composer ➜ composer /usr/local/bin/composer --version Composer version 1.8.6 2019-06-11 15:03:05 ➜ composer which composer /usr/local/bin/composer ➜ composer composer --version Composer version 1.8.6 2019-06-11 15:03:05
可见还需要手动加上可执行权限才行的。
再去试试安装php-html-parser库：
【已解决】Mac中composer install安装php的模块卡死在Updating dependencies including require-dev
然后再去看看如何使用
然后用之前的代码：
<?php require "vendor/autoload.php"; use PHPHtmlParser\Dom;
$originEvernoteHtml = ‘<div><br />……’;
$dom = new Dom;
$dom->load($originEvernoteHtml);
$codeBlockHtml = $dom->find(‘div’)[0];
echo(“codeBlockHtml=”.$codeBlockHtml);
error_log($codeBlockHtml);
?>
即可。
去调试
Launch currently open script
打印出对应值了：
codeBlockHtml=<div><br /></div>
<div><br /></div>
