Question

我得到了解析错误。我使用mysql查询表达式在heredoc中以正则表达式传递变量？

$sql = <<<SQL
    SELECT
      name, 
      full_code
    FROM M_CATEGORY 
    WHERE full_code REGEXP '^00'.$var.'[0-9][0-9][0-9]$'
    ORDER BY full_code ASC
SQL;

最初的代码是

$sql = "
SELECT
  name, 
  full_code
FROM M_CATEGORY 
WHERE full_code REGEXP '^00".$var."[0-9][0-9][0-9]$'
ORDER BY full_code ASC";

Answer 1

$sql = <<<SQL
    SELECT
      name,
      full_code
    FROM M_CATEGORY
    WHERE full_code REGEXP '^00{$var}[0-9][0-9][0-9]$'
    ORDER BY full_code ASC
SQL;

请阅读有关heredoc：http://php.net/manual/ru/language.types.string.php#language.types.string.syntax.heredoc
