像这样的东西就行了。

<?php

$host = "localhost";
$user = "root";
$pass = "";
$database ="dbname";

$conn = mysqli_connect($host, $user, $pass, $database);

if (!$conn) {
    die("Failed to connect to the database");
}

$triggersToDelete = ["trigger1", "trigger2", "trigger6"];

foreach ($triggersToDelete as $trigger) {
    if (!mysqli_query($conn, "DROP TRIGGER IF EXISTS " . htmlspecialchars($trigger, ENT_QUOTES))) {
        echo "Failed to delete trigger: " . $trigger . "<br>";
    }
}

mysqli_close($conn);

连接到数据库，对数组中的每个触发器执行drop trigger，关闭数据库连接
