php小編草莓為您介紹如何使用PHP獲取一個連接的資訊。在網路開發中,取得連線的資訊是一項常見的操作,可以幫助我們了解連線的狀態、IP位址、瀏覽器資訊等。透過PHP的內建函數和變量,我們可以輕鬆實現這項功能。接下來,我們將詳細介紹如何透過PHP獲取連接的信息,幫助您更好地掌握這項技巧。
取得 PHP 中連接的資訊
在 php 中,可以透過以下方法取得連接資訊:
1. mysqli_get_connection_stats():
#此函數傳回一個包含以下資訊的陣列:
範例:
$Mysqli = new mysqli("localhost", "user", "passWord", "database"); $stats = $mysqli->get_connection_stats(); echo "Total connect time: " . $stats["total_connect_time"] . " seconds "; echo "Total connect attempts: " . $stats["total_connect_attempts"] . " "; echo "Average connect time: " . $stats["avg_connect_time"] . " seconds "; echo "Maximum connect time: " . $stats["max_connect_time"] . " seconds "; echo "Total received bytes: " . $stats["total_recv_bytes"] . " bytes "; echo "Total sent bytes: " . $stats["total_send_bytes"] . " bytes ";
2. mysqli_get_connection_info():
此函數傳回一個包含以下資訊的字串:
範例:
$mysqli = new mysqli("localhost", "user", "password", "database"); $info = $mysqli->get_connection_info(); echo "Protocol: " . $info . " "; echo "Server: " . $info . " "; echo "Server version: " . $info . " "; echo "Threaded: " . ($info ? "Yes" : "No") . " "; echo "SSL: " . ($info ? "Yes" : "No") . " "; echo "Persistent: " . ($info ? "Yes" : "No") . " "; echo "Character set: " . $info . " ";
3. PDO::getAttribute():
#對於使用 PDO 連接的資料庫,可以使用 PDO::getAttribute()
函數來取得連接資訊:
範例:
$pdo = new PDO("mysql:host=localhost;dbname=database", "user", "password"); $serverInfo = $pdo->getAttribute(PDO::ATTR_SERVER_INFO); $serverVersion = $pdo->getAttribute(PDO::ATTR_SERVER_VERSION); $persistent = $pdo->getAttribute(PDO::ATTR_PERSISTENT); echo "Server info: " . $serverInfo . " "; echo "Server version: " . $serverVersion . " "; echo "Persistent: " . ($persistent ? "Yes" : "No") . " ";
