Collection of methods for calling MySQL stored procedures in php_PHP tutorial

This article is a collection and summary of the methods of calling MySQL stored procedures in PHP. Friends in need can refer to it. ​

Type 1: Calling a method with input and output type parameters

Copy code The code is as follows:
$returnValue = '';
try {
mysql_query ( "set @Return" );
$spname = 'P__Test_GetInfo1';
mysql_query ( "call $spname(@Return, '{$userId}', '{$pwd}')" ) or die ( "[$spname]Query failed:" . mysql_error () );
$result_return = mysql_query ( "select @Return" );
$row_return = mysql_fetch_row ( $result_return );
$returnValue = $row_return [0];
} catch (Exception $e) {
echo $e;
}
echo $returnValue; //Output variables output from the stored procedure

Type 2: Calling a method with multiple output types and multiple input type parameters

Copy code The code is as follows:
$userId = 0;
try{
Mysql_query("set @Message");
Mysql_query("set @Id");
Mysql_query("call P__Test_Login(@Message, @Id, '{$userId}', '{$pwd}')", $conn) or die("Query failed:".mysql_error());
$result_mess = mysql_query("select @Message");
$result_uid = mysql_query("select @Id");
$row_mess = mysql_fetch_row($result_mess);
$row_uid = mysql_fetch_row($result_uid);
$Proc_Error = $row_mess[0];
$uId = $row_uid[0];
}
catch(Exception $e)
{
echo $e;
}
echo 'proc return message:'$Proc_Error.'
'; //Output the variables output from the stored procedure
echo 'User id:'.$uId; //Get user id

Type 3: Calling a method that returns a result set

Copy code The code is as follows:
try {
$spname = 'P__Test_GetData';
$query = mysql_query ( "call $spname()", $conn ) or die ( "[$spname]Query failed:".mysql_error() );
while ( $row = mysql_fetch_array ( $query ) ) {
echo $row ['ProvinceID'].'::'.$row ['ProvinceName']; //Output data set
}

} catch (Exception $e) {
echo $e;
}

Type 4: Calling a method that returns multiple result sets (currently only possible through mysqli~~)

Copy code The code is as follows:

//PHP
$rows = array ();
$db = new mysqli($server,$user,$psd,$dbname);
if (mysqli_connect_errno()){
$this->message('Can not connect to MySQL server');
}
$db->query("SET NAMES UTF8");
$db->query("SET @Message");
if($db->real_query("call P__Test_GetData2(@Message)")){
do{
If($result = $db->store_result()){
               while ($row = $result->fetch_assoc()){
                    array_push($rows, $row);
                                                                                                                                $result->close();
                                                                                                              }while($db->next_result());
}
$db->close();
print_r($rows);
//Procedure
…
select * from T1 where ……
select * from T2 where ……
