從Google獲取隨機網址並將其存儲到數組中

Question

我需要檢查與某些URL的連接時間，我使用curl來完成連接（我只知道如何在時間上對1個URL進行操作，我的問題是我需要檢查許多URL，而不僅僅是1個）

這是我如何計算連接時間的示例：

$url1 = 'stackoverflow.com';
$curl1 = curl_init();
curl_setopt($curl1, CURLOPT_URL, $url1);
curl_setopt($curl1, CURLOPT_RETURNTRANSFER, TRUE);
curl_exec($curl1);
$contime1 = curl_getinfo($curl1, CURLINFO_CONNECT_TIME);
echo $contime1;

現在讓我說而不是'stackoverflow.com'網址，我想使用多個網址，例如以下數組列表：

$imones = array ("php.net","w3schools.com", "stackoverflow.com");
while (list(, $value) = each($imones)) {
$imoneslist = "$value<br />\n";

如何將$ imoneslist數組放入$ url1？

Answer 1

$imones = array ("php.net","w3schools.com", "stackoverflow.com");
foreach($imones as $url1) {
    $curl1 = curl_init();
    curl_setopt($curl1, CURLOPT_URL, $url1);
    curl_setopt($curl1, CURLOPT_RETURNTRANSFER, TRUE);
    curl_exec($curl1);
    $contime1 = curl_getinfo($curl1, CURLINFO_CONNECT_TIME);
    echo $url1 . ' took ' . $contime1 . ' seconds to connect<br />';
}

經過測試。 樣本結果：

php.net took 0.032 seconds to connect 
w3schools.com took 0.124 seconds to connect 
stackoverflow.com took 0.016 seconds to connect
