如何使用函数参数PHP
[英]How to use Functions Arguments PHP
问题描述
我试图了解在嵌套函数中使用Function参数的最佳方法：
这是我的想法：
这是一堆函数，我首先声明要在以后的其他函数中使用它们：
//Habitaciones restantes
function rleft($from, $to, $room_type_id){
//Acceso a DB
require('/some-path/database.php');
//url parameters
require ('/some-path/getparam.php');
//Hotel Room Data
$customroom = mysqli_query($conn, "SELECT * FROM hotel_room_type WHERE room_type_id = '$room_type_id'");
$customroomtotal = mysqli_num_rows($customroom);
$customroomData = mysqli_fetch_array($customroom);
$roominventory = $customroomData['room_type_inventory'];
//Obteniendo lista de disponibilidad
$customavailable = mysqli_query($conn, "SELECT * FROM booking_check_avilability WHERE room_type_id = '1' AND check_in_date = '$from' AND check_out_date = '$to'");
$customavailabletotal = mysqli_num_rows($customavailable);
mysqli_close($conn);
if($customavailabletotal > 0) {
while($customavailableData = mysqli_fetch_array($customavailable)) {
$inventariodisponible = $roominventory - $customavailableData['total_room'] -$customavailableData['blocked_inventory'];
}
} mysqli_free_result($customavailable);
mysqli_close(conn);
return $inventariodisponible;
}
//Creamos el array donde se almacenarán todos los dias entre las 2 fechas del cliente
function createRange($startDate, $endDate) {
$tmpDate = new DateTime($startDate);
$tmpEndDate = new DateTime($endDate);
$outArray = array();
do {
$outArray[] = $tmpDate->format('Y-m-d');
} while ($tmpDate->modify('+1 day') < $tmpEndDate);
return $outArray;
}
//creamos un array donde se almacenará la dispo para cada una de las fechas del cliente
function inout($room_type_id){
require ('/some-path/getparam.php');
$datearray = createRange("$fromdate", "$todate", "$room_type_id");
$arraycount = count($datearray);
$leftarray = array();
foreach ($datearray as $value) {
$from = $value;
$to = date('Y-m-d',strtotime($value . "+1 days"));
$leftarray[] = rleft($from, $to);
}
return $leftarray;
}
//Room or Rooms?
function sp(){
require ('/some-path/getparam.php');
if (rleft($fromdate, $todate, $room_type_id) == 1) {
$rq = "room";
}
else{
$rq = "rooms";
}
return $rq;
}
//Habitaciones restantes
function availablerooms(){
//Acceso a DB
require('/some-path/database.php');
//url parameters
require ('/some-path/getparam.php');
$keyarray = createrange($fromdate, $todate);
$valuearray = inout();
$joinarray = array();
foreach ($keyarray as $i => $key) {
$joinarray[$key] = $valuearray[$i];
}
return $joinarray;
}
所以这是主要功能：
//Función para checkar si hay disponibilidad para las fechas seleccionadas
function next($room_type_id){
//basic include files
require('/some-path/database.php');
//url parameters
require ('/some-path/getparam.php');
//Checkamos que haya dispo
$inoutarray = inout("$room_type_id");
foreach ($inoutarray as $value) {
if ($value < $rooms) {
echo "Sorry NO rooms available!"; //no hay habitaciones disponibles
echo "</br>";
?>
<!-- Escondemos el botón de submit de la habitación -->
<style type="text/css">.bromeliabtn{
display:none!important;
}</style>
<!-- Cambiamos el estilo del msj -->
<style type="text/css">.bromeliadsbl span{
color: #c58e21!important;
font-size: 20px!important;
line-height: 25px!important;
}</style>
<?php
$cond = true;//asignamos un valor a $cond
break; // si match entonces termina el loop
}else{
unset($cond);
$cond = false;//si hay disponibilidad entonces sumar 1 a $cond
}
}
//si las fechas tienen dispo entonces seguimos :)
if ($cond == false) {//si $cond es 2 entonces podemos seguir
allowed();
}
}
//Esta función nos permite obtener los precios tanto de temporada como normales de acuerdo a la fecha especificada.
function allowed($room_type_id){
//Acceso a la base de datos
require('/some-path/database.php');
require ('/some-path/getparam.php');
//Creamos la consulta para precios por temporada
$sql = "SELECT `seasonal_price`"
. " FROM `hotel_seasonal_price`"
. " WHERE `room_type_id` = '$room_type_id'"
. " AND `room_person` = '$Room1'"
. " AND `seasonal_price_deleted` = '0'"
. " AND '" . $fromdate . "' = seasonal_from"
//. " AND '" . $currentdate . "' = 'seasonal_to'"
. " LIMIT 1";
$result = mysqli_query($conn, $sql) or die(mysqli_error());
if (mysqli_num_rows($result) != 0) {
$seasonalprice = mysqli_query($conn, $sql);
if (!$seasonalprice) {
die('Could not get data: ' . mysqli_error());
} else {
while ($standard2 = mysqli_fetch_assoc($seasonalprice)) {
//echo "$ " . $standard2['seasonal_price'] . "";
$stdrd = $standard2['seasonal_price'];
echo "$ ";
echo number_format((float)($stdrd + ((10*$stdrd)/100)), 2, '.', ''); //sumamos el porcentaje de descuento que luego sera restado en el precio principal
echo " ";

所以这是我的疑问，这是参数： $room_type_id是我需要更改主函数以从数据库的每个房间中获取我想要的东西的唯一函数，并且每个函数都应与该变量一起用作参数来更改信息...我的问题是，如果我在主变量中定义一次房间类型ID，是否也将其接受并用于所有其他函数作为此参数的值？ 可以说：
函数next（“ 7”）;
数字7是否将用于该函数内的所有其他嵌套函数，作为同一参数的值？
在此先感谢您的帮助。

答案是“是”。
