我的查询：
[{"colorPartNumber":"10045112022164298","skuPartNumber":"0400218072057","productColor":{"identifier":"Dark blue","label":"Dark blue","hex":"#0000A0"},"productSize":{"identifier":"0","label":"0","name":"Designer","scaleLabel":"apparel-wmn","schema":{"name":"UK","labels":["8"]}},"soldOut":true,"onlyOneLeft":false,"limitedAvailability":false,"preorder":false,"comingSoon":false,"visible":true,"displayable":true,"buyable":false,"availableInPhysicalStore":false,"expectedShippingDate":null},{"colorPartNumber":"10045112022164298","skuPartNumber":"0400094632819","productColor":{"identifier":"Dark blue","label":"Dark blue","hex":"#0000A0"},"productSize":{"identifier":"1","label":"1","name":"Designer","scaleLabel":"apparel-wmn","schema":{"name":"UK","labels":["10"]}},"soldOut":true,"onlyOneLeft":false,"limitedAvailability":false,"preorder":false,"comingSoon":false,"visible":true,"displayable":true,"buyable":false,"availableInPhysicalStore":false,"expectedShippingDate":null},{"colorPartNumber":"10045112022164298","skuPartNumber":"0400218072040","productColor":{"identifier":"Dark blue","label":"Dark blue","hex":"#0000A0"},"productSize":{"identifier":"2","label":"2","name":"Designer","scaleLabel":"apparel-wmn","schema":{"name":"UK","labels":["12"]}},"soldOut":true,"onlyOneLeft":false,"limitedAvailability":false,"preorder":false,"comingSoon":false,"visible":true,"displayable":true,"buyable":false,"availableInPhysicalStore":false,"expectedShippingDate":null},{"colorPartNumber":"10045112022164298","skuPartNumber":"0400468014814","productColor":{"identifier":"Dark blue","label":"Dark blue","hex":"#0000A0"},"productSize":{"identifier":"3","label":"3","name":"Designer","scaleLabel":"apparel-wmn","schema":{"name":"UK","labels":["14"]}},"soldOut":false,"onlyOneLeft":true,"limitedAvailability":false,"preorder":false,"comingSoon":false,"visible":true,"displayable":true,"buyable":true,"availableInPhysicalStore":false,"expectedShippingDate":null}]
如果家庭成员表返回四个Ids，我需要在家庭教育表中为这四个Ids最后插入记录。

您应该使用列
created_at
应该是Family Education表中的时间戳，并按如下方式重新编写查询：
$ familyeducationDatas = Familyeducation ::其中（＆＃39; familymemberid＆＃39 ;, $ faids） - ＆GT; ORDERBY（＆＃39; created_at＆＃39;＆＃39; DESC＆＃39;） - ＆gt;首先（）;

Use SELECT MAX(id) FROM TABLE. This will return the highest currently in use primary key for the table.
