Answer 1

看起来该数组中的每个字符串都是JSON数据。

如果您使用的是现代版本的PHP，则可以使用json_decode()将数据转换为可用格式。

foreach($array as $string) {
    $json = json_decode($string);
    echo "Email = {$json->email}\n";
}

Answer 2

如果你可以发布一个数据的例子（例如：它来自哪里，一个格式正确的数组print_r()输出的例子），这将有所帮助，但是从我可以收集到的，这将得到来自阵列的电子邮件：

/* Make $array hold the given array */

$emails = array();
foreach($array as $contact){
    $emails[] = $contact['email'];
}

// All emails
print_r($emails);

Answer 3

你可以在每个数组元素上运行一个正则表达式。像这样：/“email”：“（。+？）”/

$emails = array();
foreach ($array as $str)
{
    if (preg_match('/"email":"(.+?)"/', $str, $matches))
    {
        $emails[] = $matches[1];
    }
}
