php - 使用 php 从数组中提取值

Question

我有一个如下所示的数组:

Array (
    [TIMESTAMP] => 2012-01-04T21:36:32Z
    [CORRELATIONID] => 4564e64d7f75f
    [ACK] => Failure
    [VERSION] => 51.0
    [BUILD] => 2278658
    [L_ERRORCODE0] => 10764
    [L_SHORTMESSAGE0] => This transaction cannot be processed at this time. Please try again later.
    [L_LONGMESSAGE0] => This transaction cannot be processed at this time. Please try again later.
    [L_SEVERITYCODE0] => Error
    [L_ERRORPARAMID0] => ProcessorResponse
    [L_ERRORPARAMVALUE0] => PPAV
    [AMT] => 25.00
    [CURRENCYCODE] => USD
    [AVSCODE] => N
    [CVV2MATCH] => M
)

如果我想回显 [L_LONGMESSAGE0] 的值(即“此时无法处理此事务。请稍后再试”)，我将如何使用 php 执行此操作？

更清楚地说，当我使用此命令时，我从 PayPal 获取了这个数组: urldecode(print_r($httpParsedResponseAr, true))

那么，如果该命令生成上面显示的数组，我将如何回显 [L_LONGMESSAGE0]？

预先感谢您的帮助

假设这个数组在一个$arr变量中。

echo $arr['L_LONGMESSAGE0'];
