Question

我正在尝试用heredoc撰写电子邮件内容。我不知道如何访问从以前的一些SQL查询中存储的变量并将它们插入到文本中。

这是sql查询：

$week=mysql_query('SELECT `Name`, `fname`, `Marca` FROM `personal` WHERE (`Responsabil`='.$id.') AND (`Protectie`>="'.$CurrentDate.'") AND (`Protectie`<"'.$WeekDate.'") AND (`Notificat`!=1)');
$exp=mysql_query('SELECT `Name`, `fname`, `Marca` FROM `personal` WHERE (`Responsabil`='.$id.') AND (`Protectie`<"'.$CurrentDate.'") AND (`Notificat`!=1)');
$week=mysql_fetch_assoc($week);
$exp=mysql_fetch_assoc($exp);

和问题：

$content=<<<EMAIL
We inform you that the following people:
$week['Name'] $week['fname']
$exp['Name'] $exp['fname']
are due for inspection.
EMAIL;

我需要在这里插入从查询中得到的所有名称。查询经过测试并正常运行。

Answer 1

您需要将结果变量包装在大括号中，以使它们在heredoc字符串中正确显示：

$week['Name'] = "Bloggs";
$week['fname'] = "Joe";

$exp['Name'] = "Doe";
$exp['fname'] = "Jane";

$content = <<<EMAIL
We inform you that the following people:
{$week['Name']} {$week['fname']}
{$exp['Name']} {$exp['fname']}
are due for inspection.
EMAIL;

var_dump($content);

返回：

string(87) "We inform you that the following people: Bloggs Joe Doe Jane are due for inspection."

Answer 2

试试这个，

$content=<<<EMAIL
We inform you that the following people:
{$week['name']} {$week['fname']}
{$exp['name']} {$exp['fname']}
are due for inspection.
EMAIL;

请注意，这只会打印一条记录，如果要显示结果集中的所有记录，则需要循环结果集。
