Question

我需要只与passengerData匹配的数据。我试过像下面这样做，但它不能正常工作

$getContent='passenger list: 

"passengerData":{"id-1":{...},"id-2":{...},...."id-nth":{...}};

flight List:

"flightData":{"id-1":{...},"id-2":{...},...."id-nth":{...}};';

preg_match_all('/"passengerData([^*]+\}})/', $getContent, $matches);

Answer 1

使用

/"passengerData"\s*:\s*({.*?}});$/m

见正则证明。$matches[1]必须有您想要的数据。
