PHP & MongoDB - Error Handling
MongoDB 驱动器操作会抛出数据库操作异常，并且可以使用以下语法轻松地捕获这些异常：
try {
} catch (MongoDB\Driver\Exception\Exception $e) {
echo "Exception:", $e->getMessage(), "<br/>";
echo "File:", $e->getFile(), "<br/>";
echo "Line:", $e->getLine(), "<br/>";
}Example
尝试以下示例以检查 MongoDB 服务器中的数据库操作错误 −
将以下示例复制粘贴到 mongodb_example.php −
<?php
try {
// connect to mongodb
$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");
// Create a Command Instance
$createCollection = new MongoDB\Driver\Command(["create" => "sampleCollection"]);
// Execute the command on the database
$cursor = $manager->executeCommand("myDb", $createCollection);
echo "Collection created.";
} catch (MongoDB\Driver\Exception\Exception $e) {
echo "Exception:", $e->getMessage(), "<br/>";
echo "File:", $e->getFile(), "<br/>";
echo "Line:", $e->getLine(), "<br/>";
}
?>
