pg_tty

(PHP 4, PHP 5, PHP 7, PHP 8)

pg_tty 返回跟连接相关的 tty 名

说明

pg_tty(?PgSql\Connection $connection = null): string

pg_tty() 返回指定 PostgreSQL connection 实例在服务器端调试输出发送的 tty 名。

注意:

pg_tty() 已经过时,因为服务器不再关注 TTY 设置,但为了向后兼容性,该函数仍然保留。

参数

connection

An PgSql\Connection instance. When connection is null, the default connection is used. The default connection is the last connection made by pg_connect() or pg_pconnect().

警告

As of PHP 8.1.0, using the default connection is deprecated.

返回值

string,包含 connection 的调试 TTY。

更新日志

版本 说明
8.1.0 现在 connection 参数接受 PgSql\Connection 实例,之前接受 resource
8.0.0 connection 现在可为 null。

示例

示例 #1 pg_tty() 示例

<?php
$pgsql_conn

$pgsql_conn) {
print
"Server debug TTY is: " . pg_tty($pgsql_conn) . "<br/>\n";
} else {

pg_last_error($pgsql_conn);
exit;
}
?>
