如何使用php preg_split分割字符串并保留部分使用的分隔符？

Question

I need to use preg_split to split the string below by using "};{" as the delimiter. But I want to keep/return the } and { in the returned array.

Regex can do so much, but wondering if this is possible using preg_split.

{'aid':10,'aSL'{'ac':true,'g_ac':true,'stats':0,'ldb':0,'g_':0},'hs':'4.8','l_p':1229241600},{'aid':80,'aSL':{'ac':0,'g_ac':0,'stats':0,'ldb':0,'g_':0}},{'aid':100,'aSL':{'ac':0,'g_ac':0,'stats':0,'ldb':0,'g_':0}},{'aid':30,'aSL':{'ac':true,'g_ac':true,'stats':0,'ldb':0,'g_':0}},{'aid':40,'aSL':{'ac':0,'g_ac':0,'stats':0,'ldb':0,'g_':0}},{'aid':60,'aSL':{'ac':true,'g_ac':true,'stats':0,'ldb':0,'g_':0}}

I want it to return like this

[0] => {'aid':10,'aSL':{'ac':true,'g_ac':true,'stats':0,'ldb':0,'g_':0},'hs':'4.8','l_p':1229241600}
[1] => {'aid':80,'aSL':{'ac':0,'g_ac':0,'stats':0,'ldb':0,'g_':0}
[2] => {'aid':100,'aSL':{'ac':0,'g_ac':0,'stats':0,'ldb':0,'g_':0}
[3] => {'aid':30,'aSL':{'ac':true,'g_ac':true,'stats':0,'ldb':0,'g_':0}
[4] => {'aid':40,'aSL':{'ac':0,'g_ac':0,'stats':0,'ldb':0,'g_':0}
[5] => {'aid':60,'aSL':{'ac':true,'g_ac':true,'stats':0,'ldb':0,'g_':0}

To not include } { in the split-sequence, could use lookarounds instead:

(?<=}),(?={) or (?<=});(?={)

For use with the regex-functions need to put that into delimiters: /pattern/
