来自 header 的可能 SIP:
"unknown-caller-name" <sip:<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="ee9b808580819980c38f8087ae9e8c96c08a81838f8780c08d8183" rel="noreferrer noopener nofollow">[email protected]</a>:5066;user=phone>
"Henry Tirta" <sip:<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="4c75797d0c2823212d2522622f2321" rel="noreferrer noopener nofollow">[email protected]</a>>
我需要提取<sip:之间的SIP号码& @使用正则表达式从 php 中的上述 header 中获取。此 SIP 号码长度会有所不同。
$from = "\"User Name\" <sip:<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="d0e1e9e990a0b2a8fea4b5a3a4b4bfbdb1b9befeb3bfbd" rel="noreferrer noopener nofollow">[email protected]</a>>";
$matches = array();
$pattern = '/[A-Za-z0-9_-]+@[A-Za-z0-9_-]+\.([A-Za-z0-9_-][A-Za-z0-9_]+)/';
preg_match($pattern,$from,$matches);
$number = explode('@', $matches[0])[0];
echo $number;
还有更好的方法吗？
最佳答案
让我们简单一点:
$from = '"unknown-caller-name" <sip:<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="99ecf7f2f7f6eef7b4f8f7f0d9e9fbe1b7fdf6f4f8f0f7b7faf6f4" rel="noreferrer noopener nofollow">[email protected]</a>:5066;user=phone>';
if(preg_match('#<sip:(.*?)@#', $from, $id)){
echo $id[1];
}else{
echo 'no match';
}
说明:
-
<sip::匹配<sip: -
(.*?):匹配并分组所有不贪心的东西，直到... -
@:@已找到/匹配。
