我正在为一个网站开发一个php web应用程序，我想将一些变量从一个php文件传递到另一个。我用包含文件尝试了旧时尚方式，但没有成功。我还尝试在全局范围内设置变量，但仍然无效。 first.php文件中的代码是：
function rc_getAvailableVehicles($pickup_timestamp, $return_timestamp, $vehicle_classes=array()) {
global
$wpdb;
$rc_currency = RC_Registry::get('rc_currency');
$where_classes = "";
if ($vehicle_classes) {
foreach($vehicle_classes as $vehicle_class) {
$where_classes[] = " v.class = '". $wpdb->escape($vehicle_class) ."'";
}
$where_classes = "AND (".implode(' OR ', $where_classes).") ";
}
$sql = "SELECT *
FROM ".$wpdb->rc_vehicles." v
WHERE v.quantity > (SELECT COUNT(*) FROM ".$wpdb->rc_bookings." b WHERE b.vehicle_id = v.vehicle_id AND ((UNIX_TIMESTAMP(b.pickup_date) >= '". (int)$pickup_timestamp ."' AND UNIX_TIMESTAMP(b.pickup_date) < '". (int)$return_timestamp ."') || (UNIX_TIMESTAMP(b.pickup_date) < '". (int)$pickup_timestamp ."' AND UNIX_TIMESTAMP(b.return_date) >= '". (int)$pickup_timestamp ."')) AND (b.status != 'new' AND b.status != 'canceled') AND b.trash = '0') ".$where_classes."AND v.status = '1' AND v.archive = '0'
ORDER BY v.rent ASC";
$results = $wpdb->get_results($sql,ARRAY_A);
$vehicles = array();
$rental_days = ceil(($return_timestamp-$pickup_timestamp)/91800);
$xfee = get_field('another_location_fee');
$xfee2 = get_field('return_to_another_location_fee_2');
if ($results) {
foreach ($results as $result) {
if ($result['image'] && file_exists(RC_UPLOADS_DIR . "vehicle_" . $result['image'])) {
$image = RC_UPLOADS_URL . 'vehicle_' . $result['image'];
$image_thumb = RC_UPLOADS_URL . 'cache/' . rc_image_resize(RC_UPLOADS_DIR . "vehicle_" . $result['image'], 220, 160);
} else {
$image = '';
$image_thumb = '';
}
$result['description'] = do_shortcode($result['description']);
$description = html_entity_decode($result['description'], ENT_QUOTES, 'UTF-8');

我希望回显$rent
file2.php变量
我试过了
echo $rent;没有成功！
答案 0 :(得分：0)
$pass = "anything";
include_once ('file2.php');
从file2.php，您可以访问$pass变量。
答案 1 :(得分：0)
您需要调用file2.php
中存在的file1.php中的函数离。在file1.php中你可以调用函数return_rent
return_rent($rent);
在file2中然后你创建函数
function return_rent($var){
echo $rent;
}
答案 2 :(得分：0)
您遇到代码顺序问题
$vehicle_meta = rc_getVehicleMeta($result['vehicle_id']);
应该在填充租金变量之前，
include_once ('file2.php');
应该在您填充租金变量之后。
