你好，我正在做一个项目，通过从表单收集数据，这些数据从表单发布到网络服务和数据库。它们都可以正常工作，但我需要进行一些检查。
我尝试根据第一个函数何时失败来停止函数的流程。
第一个函数是将收集的数据发布到 Web 服务的函数。 下面 ：
<?php
require_once('includes/nusoap.php');
$wsdlfile = "https://niid.autoreglive.org/nia_api/service.asmx?wsdl";
$wsdlfile = "https://www.niid.org/NIA_API/Service.asmx?wsdl";
//$wsdlfile = "http://localhost:82/cscart/service/index.php";
$msg = "<?xml version='"1.0'" encoding='"utf-8'" ?>

$Username = '******';
$Password = '******';
$NiaNaicomID = '******';
$PolicyNo = $_POST['Policy_Number'];
$InsuredName = $_POST['Insured_Name'];
$ContactAddress = $_POST['Residential_Address'];

$SumAssured = 2.3;

$GeographicalZone = '6';
$params = array('Username' => $Username,

);
$s = new nusoap_client($wsdlfile, 'wsdl');
//$s = new nusoap_client($wsdlfile);
// if (empty($proxyhost))
// {
// }else
// {
// $s->setHTTPProxy($proxyhost,$proxyport,$proxyusr,$proxypassword);
// }
$result = $s->call('Vehicle_Policy_Push', $params, '', '', false, true);
if($result){
print_r($result);
echo '<META HTTP-EQUIV="Refresh" Content="3; URL=account.php">';
}else{
echo '<META HTTP-EQUIV="Refresh" Content="3; URL=policy_active.php">';
}
?>
这是我在下面第一个函数失败时想要停止的第二个函数：
<?php
$con=mysqli_connect
("localhost","*******","*******","*******");
//Checkconnection
if(mysqli_connect_errno())
{
echo"FailedtoconnecttoMySQL:".mysqli_connect_error();
}
$check="SELECT * FROM transactions WHERE year_find = '$_POST[year_find]'";
$rs = mysqli_query($con,$check);
$data = mysqli_fetch_array($rs, MYSQLI_NUM);
if($data[0] > 1) {
echo '<META HTTP-EQUIV="Refresh" Content="3; URL=policy_active.php">';
}
else
{
$sql="INSERT INTO transactions(month_search,month,year_search,year,year_find,Username,Insured_Name,combined,Residential_Address,Telephone,Email,Make_Of_Car,Model,Engine_Number,Year_Of_Manufacture,Chassis_Number,Vehicle_Class,Colour,Registeration_Number,Product_Type,Premium,Policy_Number,Start_Date,Expiry_Date,Date_Begin,Type_Of_Insurance,Status, Transaction_id)VALUES('$_POST[month_search]','$_POST[month]','$_POST[year_year]','$_POST[newyear]','$_POST[year_find]','$_POST[Username]','$_POST[Insured_Name]','$_POST[combined]','$_POST[Residential_Address]','$_POST[phone]','$_POST[Email]','$_POST[Make_Of_Car]','$_POST[Model]','$_POST[Engine_Number]','$_POST[Year_Of_Manufacture]','$_POST[Chassis_Number]','$_POST[Vehicle_Class]','$_POST[Colour]','$_POST[Registeration_Number]','$_POST[Product_Type]','$_POST[Premium]','$_POST[Policy_Number]','$_POST[Date]','$_POST[Date_Expiry]','$_POST[Date_Begin]','$_POST[Type_Of_Insurance]','$_POST[Status]','$_POST[Transaction_id]')";
}
if(!mysqli_query($con,$sql))
{
die('Error:'.mysqli_error
($con));
}
echo '<META HTTP-EQUIV="Refresh" Content="3; URL=account.php">';
mysqli_close($con);
?>
第二个函数将数据提交到数据库。普通我希望当第一个函数失败时第二个函数无法运行，但 im 错了，它转移到另一个函数，然后将不需要的数据提交到数据库。
所以我想知道我如何根据第一个函数的失败来停止第二个函数。
您应该尝试使用 try...catch 块。仅当第一个函数未引发异常时，才会调用第二个函数。
function postData(){
// code to post data here
// throw exception when something fails
throw new Exception('I am an exception message');
}
function saveData(){
// code to save data here
}
try{
postData();
saveData();
}
catch( Exception $e ){
echo $e->getMessage();
}
