我有一个数组，需要从中提取一段数据。我没有编写创建数组的原始代码，它的行为似乎不像我预期的那样，我的数组知识正在增长，但仍然相当新。这是阵列：
array(31) { ["title"]=> string(13) "Title of work" ["abstr"]=> string(163) "
Epsum factorial non deposit quid pro quo hic escorol. Olypian quarrels et gorilla congolium sic ad nauseum. Souvlaki ignitus carborundum e pluribus unum.
" ["outcomes"]=> string(163) "

我可以找出如何提取和回显标题等变量，甚至是顶级数组中的整个演示者数组，但我无法从演示者数组中提取电子邮件地址。如有任何帮助，我们将不胜感激。
数组的格式很奇怪，但我猜呈现者的值是一个带值的长字符串。
要获取电子邮件地址，请使用以下方法：
$strPresenters = $baseArray['presenters']; //actually I can't even track how to get to presenters, but you can figure that out with trial and error
preg_match('/email_address = ([^'s]*)/', $strPresenters, $aryMatch);
$strEmail = $aryMatch[1];
如果格式完全不同，您可能需要调整正则表达式。
