Two array merge issues

Array 1:

$arr 1=array ([0] = = Array ([TIME] = 8:00[detail] = = Array ([0] = = Array ([Caseid] = 31[casename] = Zhang San) [1 ] = = Array ([Caseid] = 32[casename] = Lee IV) [2] = = Array ([Caseid] = 33[casename] = Harry))) [1] = Ar Ray ([TIME] = 12:00[detail] = = Array ([0] = = Array ([Caseid] = 32[casename] = Lee IV) [1] = = Array ([Caseid] = = 33[casename] + Harry)) [2] = = Array ([TIME] = 18:00[detail] = = Array ([0] = = Array ([Caseid] = 31 [Casename] = Zhang San) [1] = = Array ([Caseid] = 32[casename] = Lee IV) [2] = = Array ([Caseid] = 33[casename] =&G T Harry))))

Array 2

$arr 2=array ([0] = = Array ([TIME] = 8:00[detail2] = = Array ([0] = = Array ([Caseid] = 41[casename] = Liu Bei))  ) [1] = = Array ([TIME] = 16:00[detail2] = = Array ([0] = = Array ([Caseid] = 42[casename] = Zhang Fei) [1] = = Array ([Caseid] = 43[casename] = Zhao Yun))) [2] = = Array ([TIME] = 18:00[detail2] = = Array ([0] = = Array (  [Caseid] (= 43[casename] = Zhao Yun))) [2] = = Array ([TIME] = 22:00[detail2] = = Array ([0] = = Array ([Caseid] (= 45[casename])))) after merging, the final array should appear like this: [code=php] $result =array ([0] = = Array ([TIME] = 8:00[detail] =&gt ;  Array ([0] = = Array ([Caseid] = 31[casename] = Zhang San) [1] = = Array ([Caseid] (= = 32[casename] = Li iv) [2] = = Array ([Caseid] = 33[casename] = Harry)) [DETAIL2] = = Array ([0] = = Array ([Caseid] + 41[casename] = Liu Bei ))) [1] = = Array ([TIME] = 12:00[detail] = = Array ([0] = = Array ([Caseid] = 32[casename] = Lee IV) [1] =&gt ; Array ([Caseid] = 33[casename] = Harry)) [DETAIL2] = = Array ()) [2] = = Array ([TIME] = 16:00[detail] = = Array () [DETAIL2] = Array ([0] = = Array ([Caseid] = 42[casename] = Zhang Fei) [1] = = Array ([Caseid] = 43[casename] = Zhao Yun))) [3 ] = = Array ([TIME] = 18:00[detail] = = Array ([0] = = Array ([Caseid] = 31[casename] = Zhang San) [1] = = Array ([Caseid] = 32[casename] = Lee IV) [2] = = Array ([Caseid] = 33[casename] = Harry)) [DETAIL2] = = Array ([0] = = Array ([Caseid] = 43[casename]  = (Zhao Yun))) [4] = = Array ([TIME] = 22:00[detail] = = Array () [detail2] = = Array ([0] = = Array ([Caseid] + =) 45[casename])))

PHP provides a rich range of functions
You should move it yourself.

Array 2 is problematic, 18:00, and 22:00 subscript are 2, change 22:00 to 3

Thank you very much, I took care of myself.
