您需要连接到数据库并执行查询以检索数据并获取它。为此，您可以使用mysqli或PDO。这是一个关于如何使用 mysqli从$tbl_name具有列的表中获取数据的示例。project_name

$mysqli = new mysqli("localhost", "user", "password", "database");
if ($mysqli->connect_errno) {
echo "Failed to connect to MySQL: (" . $mysqli->connect_errno . ")";
exit();
}

$query = "SELECT * FROM `$tbl_name`";

if ($result = $mysqli->query($query)) {

    /* fetch associative array */
    while ($row = $result->fetch_assoc()) {
        printf ("%s \n", $row["project_name"]);
    }

    /* free result set */
    $result->free();
}

/* close connection */
$mysqli->close();

我更喜欢这个：

function getFieldSelect($name, $selected, $values, $attributes) {
    $r = "<select name=\"$name\" $attributes>";
    foreach ($values as $k => $v) {
        if ($k == $selected) {
            $sel = "selected";
        } else {
            $sel = "";
        }
        $r .= "<option  value=\"$k\" $sel>$v</option>\n";
    }
    $r .= "</select>";
    return $r;
}

我从 DB 中获取值并以数组格式将其提供给我的函数。我认为这是打印选择字段最灵活的方式。您可以使用数据库来获取值或任何数组。

<?php
$db_query_project= mysql_query("SELECT * FROM $tbl_name");

echo '<form name="report" method="post" action="">';
echo '<label for="project">Projekt </label>';
echo '<select name="project_select">';

echo '<option>Test</option>';

while( $row = mysql_fetch_assoc( $db_query_project ) )
{
        echo '<option>'.$row['project_name'].'</option>';
}
echo '</select>';
echo '</form>';
