HomeBackend DevelopmentPHP Tutorialphp 正则表达式提取文本中的所有邮箱地址,不是一个邮箱

php 提取文本中的所有邮箱地址,或者一个字符串中的所有邮箱地址
例如我的文本是:
汉字的是scdd test001@qq.com asda test002@qq.com 你后am test009@aa.com
匹配的结果应该是
test001@qq.com
test002@qq.com
test009@aa.com
我的代码如下;

<code><?php $str = '汉字的是scdd test001@qq.com asda test002@qq.com 你后am test009@aa.com ';
$preg = "/([a-z0-9\-_\.]+@[a-z0-9]+\.[a-z0-9\-_\.]+)+/i";
if (preg_match($preg, $str , $matches)) {
    print_r($matches);
}</code></code>

目前只能匹配到一个Email地址 test001@qq.com ,其他2个目前匹配不到,,,,,要使用贪婪模式匹配吗?
请指教!!

Session in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.
