如何在我的PHP脚本中调用存储过程？

Question

我正在PhpMyAdmin中工作，我创建了一个包含一些数据的表：Suppliers（id_sup，name，raiing，city）和一个简单的过程（SupplierInfo（）），该过程执行以下操作：选择* From Suppliers。现在，我想在我的php脚本中调用该过程，以便它显示查询结果。

<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "practice";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

$sql = 'SupplierInfo()';
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    echo "<table><tr><th>id_sup</th><th>name</th><th>rating</th><th>city</th></tr>";
    // output data of each row
    while($row = $result->fetch_assoc()) {
        echo "<tr><td>".$row["id_sup"]."</td><td>".$row["name"]."</td><td>".$row["rating"]."</td><td>".$row["city"]."</td></tr>";
    }
    echo "</table>";
} else {
    echo "0 results";
}
$conn->close();
?>

这里有一个示例：

$conn = new mysqli($servername, $username, $password, $dbname);

//run the store proc
$result = mysqli_query($conn, "CALL SupplierInfo");

//loop the result set
while ($row = mysqli_fetch_array($result)){     
  echo $row[0] . " - " . + $row[1]; 
}
