要設(shè)置PHP Socket的超時(shí)時(shí)間，您需要在創(chuàng)建套接字后使用settimeo()函數(shù)

<?php
// 創(chuàng)建一個(gè)新的socket
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
if (!$socket) {
    echo "socket_create() failed: reason: " . socket_strerror(socket_last_error()) . "\n";
    exit();
}

// 設(shè)置超時(shí)時(shí)間（秒）
$timeout = 10;
socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO, ['sec' => $timeout, 'usec' => 0]);
socket_set_option($socket, SOL_SOCKET, SO_SNDTIMEO, ['sec' => $timeout, 'usec' => 0]);

// 連接到服務(wù)器
$host = '127.0.0.1';
$port = 80;
$result = socket_connect($socket, $host, $port);
if (!$result) {
    echo "socket_connect() failed.\nReason: " . socket_strerror(socket_last_error($socket)) . "\n";
    exit();
}

// 從服務(wù)器接收數(shù)據(jù)
$buffer = '';
socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO, ['sec' => $timeout, 'usec' => 0]);
$data = socket_read($socket, 2048, PHP_BINARY_READ);
if ($data === false) {
    echo "socket_read() failed.\nReason: " . socket_strerror(socket_last_error($socket)) . "\n";
    exit();
}

echo "Received data: {$data}\n";

// 關(guān)閉套接字
socket_close($socket);
?>

在這個(gè)示例中，我們將超時(shí)時(shí)間設(shè)置為10秒。您可以根據(jù)需要更改$timeout變量的值。
