如何從字符串中找到「<< >>」字樣

Question

我嘗試了一些正則表達式模式，但仍找不到一些解決方案。

我想從以下字符串中獲得<< >>單詞。

$string = "Yes! Bariatric surgery is covered under your plan. Click <<COMPANY>> here to contact a local surgeon and ask them to confirm your insurance benefits for free. See our <<INSURANCE>> page for coverage criteria or scroll down this page to learn more."; 
$dash = substr($string,strpos($string,"<<"),strpos($string,">>")); 

如果有人知道請幫助我。

謝謝。

這個正則表達式匹配<<和>>

\<{2}([^\>]+)\>{2}

preg_match_all("/\<{2}([^\>]+)\>{2}/", $string, $matches); 
print_r($matches);
