正則表達式 - 提取兩個自定義分隔符內的內容

Question

想要檢查，我是非常新的正則表達式，我試圖提取2個自定義分隔符內的自定義日誌文件的內容。我應該怎麼做？我試過preg_match('/-----BEGIN DEPLOYMENT-----(.*?)-----END DEPLOYMENT-----/s', $logFile, $extracted);，但它似乎不能正常工作。以下是我爲我的bitbucket自動部署功能所做的日誌文件示例。

-----BEGIN DEPLOYMENT-----

Answer 1

你的正則表達式看起來做工精細，但實際上捕獲所有出現，你需要使用preg_match_all方法：

preg_match_all('/-----BEGIN DEPLOYMENT-----(.*?)-----END DEPLOYMENT-----/s', $logFile, $extracted); 
print_r($extracted);
