php - 试图获取 id 以链接到下一页

Question

我试图从这段代码的链接中获取数据并得到如下所示的错误，代码的第 3 行可能有什么问题？

while ($row = mysql_fetch_assoc($result))
    {
        echo "<a href=\"edit_employee.php?$row['employee_id_passport']\">" . $row['first_name'] ." " . $row['surname'] . "</a>";

        echo "<br />";
    }

错误是

Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in /Library/WebServer/Documents/practice/employee/view_employee.php on line 14 

Answer 1

删除单引号:

echo "<a href=\"edit_employee.php?$row[employee_id_passport]\">" . $row['first_name'] ." " . $row['surname'] . "</a>";
