问题记录
WordPress保存文章时，文章内包含的反斜杠会被当做转义符，导致保存后丢失反斜杠。
1. 复现问题
这个问题发现很久了，比如文章内包含PHP代码，又恰好代码使用了命名空间时，原代码：
<code class="language-php" style="font-size: 0.78rem; box-sizing: border-box; line-height: 1.5; overflow-wrap: normal; word-break: normal; word-spacing: normal; background-position: 0px 0px; background-color: initial; text-shadow: 0 1px var(--theme-pre-code-shadow); font-family: Consolas, Monaco, "Andale Mono", "Ubuntu Mono", monospace; white-space: inherit; tab-size: 4; hyphens: none; -webkit-tap-highlight-color: rgba(255, 255, 255, 0) !important;"><span class="token php language-php" style="font-size: 0.78rem; color: rgb(101, 164, 227); box-sizing: border-box; line-height: 1.75; overflow-wrap: break-word; word-break: break-all; word-spacing: normal; -webkit-tap-highlight-color: rgba(255, 255, 255, 0) !important;"><span class="token delimiter important" style="font-size: 0.78rem; color: rgb(238, 153, 0); box-sizing: border-box; line-height: 1.75; overflow-wrap: break-word; word-break: break-all; word-spacing: normal; -webkit-tap-highlight-color: rgba(255, 255, 255, 0) !important; font-weight: 700;"><?php</span> <span class="token keyword keyword-use" style="font-size: 0.78rem; color: rgb(0, 119, 170); box-sizing: border-box; line-height: 1.75; overflow-wrap: break-word; word-break: break-all; word-spacing: normal; -webkit-tap-highlight-color: rgba(255, 255, 255, 0) !important;">use</span> <span class="token package" style="font-size: 0.78rem; box-sizing: border-box; line-height: 1.75; overflow-wrap: break-word; word-break: break-all; word-spacing: normal; -webkit-tap-highlight-color: rgba(255, 255, 255, 0) !important;"><span class="token punctuation" style="font-size: 0.78rem; color: rgb(153, 153, 153); box-sizing: border-box; line-height: 1.75; overflow-wrap: break-word; word-break: break-all; word-spacing: normal; -webkit-tap-highlight-color: rgba(255, 255, 255, 0) !important;">\</span>Swoole<span class="token punctuation" style="font-size: 0.78rem; color: rgb(153, 153, 153); box-sizing: border-box; line-height: 1.75; overflow-wrap: break-word; word-break: break-all; word-spacing: normal; -webkit-tap-highlight-color: rgba(255, 255, 255, 0) !important;">\</span>Server</span><span class="token punctuation" style="font-size: 0.78rem; color: rgb(153, 153, 153); box-sizing: border-box; line-height: 1.75; overflow-wrap: break-word; word-break: break-all; word-spacing: normal; -webkit-tap-highlight-color: rgba(255, 255, 255, 0) !important;">;</span> </span><span aria-hidden="true" class="line-numbers-rows" style="font-size: 14.976px; color: rgb(101, 164, 227); box-sizing: border-box; line-height: 1.75; overflow-wrap: break-word; word-break: break-all; word-spacing: normal; -webkit-tap-highlight-color: rgba(255, 255, 255, 0) !important; position: absolute; pointer-events: none; top: 0px; left: -3.8em; width: 3em; letter-spacing: -1px; border-right: 1px solid rgb(153, 153, 153); user-select: none;"><span style="font-size: 0.78rem; box-sizing: border-box; line-height: 1.75; overflow-wrap: break-word; word-break: break-all; word-spacing: normal; display: block; counter-increment: linenumber 1; -webkit-tap-highlight-color: rgba(255, 255, 255, 0) !important;"></span><span style="font-size: 0.78rem; box-sizing: border-box; line-height: 1.75; overflow-wrap: break-word; word-break: break-all; word-spacing: normal; display: block; counter-increment: linenumber 1; -webkit-tap-highlight-color: rgba(255, 255, 255, 0) !important;"></span></span></code>
会变成下面这样：
<code class="language-php" style="font-size: 0.78rem; box-sizing: border-box; line-height: 1.5; overflow-wrap: normal; word-break: normal; word-spacing: normal; background-position: 0px 0px; background-color: initial; text-shadow: 0 1px var(--theme-pre-code-shadow); font-family: Consolas, Monaco, "Andale Mono", "Ubuntu Mono", monospace; white-space: inherit; tab-size: 4; hyphens: none; -webkit-tap-highlight-color: rgba(255, 255, 255, 0) !important;"><span class="token php language-php" style="font-size: 0.78rem; color: rgb(101, 164, 227); box-sizing: border-box; line-height: 1.75; overflow-wrap: break-word; word-break: break-all; word-spacing: normal; -webkit-tap-highlight-color: rgba(255, 255, 255, 0) !important;"><span class="token delimiter important" style="font-size: 0.78rem; color: rgb(238, 153, 0); box-sizing: border-box; line-height: 1.75; overflow-wrap: break-word; word-break: break-all; word-spacing: normal; -webkit-tap-highlight-color: rgba(255, 255, 255, 0) !important; font-weight: 700;"><?php</span> <span class="token keyword keyword-use" style="font-size: 0.78rem; color: rgb(0, 119, 170); box-sizing: border-box; line-height: 1.75; overflow-wrap: break-word; word-break: break-all; word-spacing: normal; -webkit-tap-highlight-color: rgba(255, 255, 255, 0) !important;">use</span> <span class="token package" style="font-size: 0.78rem; box-sizing: border-box; line-height: 1.75; overflow-wrap: break-word; word-break: break-all; word-spacing: normal; -webkit-tap-highlight-color: rgba(255, 255, 255, 0) !important;">SwooleServer</span><span class="token punctuation" style="font-size: 0.78rem; color: rgb(153, 153, 153); box-sizing: border-box; line-height: 1.75; overflow-wrap: break-word; word-break: break-all; word-spacing: normal; -webkit-tap-highlight-color: rgba(255, 255, 255, 0) !important;">;</span> </span><span aria-hidden="true" class="line-numbers-rows" style="font-size: 14.976px; color: rgb(101, 164, 227); box-sizing: border-box; line-height: 1.75; overflow-wrap: break-word; word-break: break-all; word-spacing: normal; -webkit-tap-highlight-color: rgba(255, 255, 255, 0) !important; position: absolute; pointer-events: none; top: 0px; left: -3.8em; width: 3em; letter-spacing: -1px; border-right: 1px solid rgb(153, 153, 153); user-select: none;"><span style="font-size: 0.78rem; box-sizing: border-box; line-height: 1.75; overflow-wrap: break-word; word-break: break-all; word-spacing: normal; display: block; counter-increment: linenumber 1; -webkit-tap-highlight-color: rgba(255, 255, 255, 0) !important;"></span><span style="font-size: 0.78rem; box-sizing: border-box; line-height: 1.75; overflow-wrap: break-word; word-break: break-all; word-spacing: normal; display: block; counter-increment: linenumber 1; -webkit-tap-highlight-color: rgba(255, 255, 255, 0) !important;"></span></span></code>
产生的影响也不小，只好研究研究如何解决这个问题。
2. 解决问题
通过对保存的环节进行分析，确定是在保存到数据库之前发生了转义，解决代码如下：
<code class="language-php" style="font-size: 0.78rem; box-sizing: border-box; line-height: 1.5; overflow-wrap: normal; word-break: normal; word-spacing: normal; background-position: 0px 0px; background-color: initial; text-shadow: 0 1px var(--theme-pre-code-shadow); font-family: Consolas, Monaco, "Andale Mono", "Ubuntu Mono", monospace; white-space: inherit; tab-size: 4; hyphens: none; -webkit-tap-highlight-color: rgba(255, 255, 255, 0) !important;"><span class="token doc-comment comment" style="font-size: 0.78rem; color: rgb(112, 128, 144); box-sizing: border-box; line-height: 1.75; overflow-wrap: break-word; word-break: break-all; word-spacing: normal; -webkit-tap-highlight-color: rgba(255, 255, 255, 0) !important;">/**
