WordPress 如何檢查外掛字首的唯一性？

問題描述

為了避免與其他外掛衝突，應該使用唯一字首的所有全域性函式，操作和外掛字首，例如：

function xyz_function_name() { ... }

問題是，如何驗證 xyz 確實是獨一無二的？例如，Yoast SEO 使用 wpseo_，我可以想象其他 SEO 外掛也可以輕鬆使用。搜尋可用的 WordPress 外掛潛在的衝突的最佳方式是什麼？還是在那裡？

最佳解決方案

您可以使用 Mark Jaquith 的 WordPres Plugin Directory Slurper shell 指令碼從 WordPress.org repo 下載所有外掛的最新版本。一旦外掛被下載，你可以 grep 你想檢查的外掛/鉤子字首，例如：

grep -r --include=*.php 'wpseo_' ./

將 WordPres Plugin Directory Slurper 軟體包解壓縮到檔案根目錄。預設目錄名為 WordPress-Plugin-Directory-Slurper，它包含：

  /plugins/
  /readmes/
  /zips/
  LICENSE
  README.markdown
  update

從 WordPress-Plugin-Directory-Slurper 目錄中執行 php update 執行 bash 指令碼。拉鍊外掛將下載到/zips 並提取到/plugins 。整個售後服務在 15GB 左右，首次下載需要幾個小時。

update 指令碼的內容：
