Question

有人可以建议我如何最好地将wp-config.php中的以下内容与regex

进行匹配

define('AUTH_KEY',         'put your unique phrase here');
define('SECURE_AUTH_KEY',  'put your unique phrase here');
define('LOGGED_IN_KEY',    'put your unique phrase here');
define('NONCE_KEY',        'put your unique phrase here');
define('AUTH_SALT',        'put your unique phrase here');
define('SECURE_AUTH_SALT', 'put your unique phrase here');
define('LOGGED_IN_SALT',   'put your unique phrase here');
define('NONCE_SALT',       'put your unique phrase here');

Answer 1

非常有用的正则表达式测试器https://regex101.com/r/gmlGpT/1

define\(['"][A-Z_]+['"]\,\s+['"](?<key>[\w\s]+)['"]\);

Answer 2

$string = "define('AUTH_KEY',         'put your unique phrase here');'";
$string .= 'define("SECURE_AUTH_KEY",         "put your unique phrase here");';
$string .= 'define("LOGGED_IN_KEY",         \'put your unique phrase here\');';
preg_match_all("/define\s*\(\s*['\"]([^'\"]+)['\"]\s*,\s*['\"]([^'\"]+)['\"]\s*\)/", $string, $matches);
var_export($matches);

嘿，它很难看，看起来像Perl，我有宾至如归的感觉！

那将产生

array (
  0 =>
  array (
    0 => 'define(\'AUTH_KEY\',         \'put your unique phrase here\')',
    1 => 'define("SECURE_AUTH_KEY",         "put your unique phrase here")',
    2 => 'define("LOGGED_IN_KEY",         \'put your unique phrase here\')',
  ),
  1 =>
  array (
    0 => 'AUTH_KEY',
    1 => 'SECURE_AUTH_KEY',
    2 => 'LOGGED_IN_KEY',
  ),
  2 =>
  array (
    0 => 'put your unique phrase here',
    1 => 'put your unique phrase here',
    2 => 'put your unique phrase here',
  ),
)

基本上，这假设在两个字符串中都没有'nor'，那些只会用于开始和结束字符串。它会偶然发生在像define("myKey', 'test')这样奇怪的事情上，但那些可能是不是问题，因为PHP不喜欢编译它们。

顺便说一下，你可以通过简单地包含wp_config.php然后说print LOGGED_IN_KEY来避免使用正则表达式。
