Split a group of data into six output algorithms

?

$ GroupCount = 6; // number of groups

$ UserIdList = array (1, 2, 3, 4, 5, 6, 7, 8, 9, 10 );

$ Size = count ($ userIdList );

$ SizeGroupPer = floor ($ size/$ groupCount); // The number of groups allocated.

$ CriticalValue = $ size % $ groupCount; // critical value
$ StartIndex = 0;
$ EndIndex = 0;
For ($ I = 0; $ I <$ groupCount; $ I ++ ){?

?

??????????? If ($ I <$ critical) {// indicates which groups can be assigned multiple times

?????????????? $ EndIndex = $ startIndex + $ sizeGroupPer + 1;

????????????} Else {

??????????????? $ EndIndex = $ startIndex + $ sizeGroupPer;

????????????}

??
???????????? $ StrGroup = "";?

??????????? For ($ j = $ startIndex; $ j <$ endIndex; $ j ++ ){
?????????????? If ($ j + 1) ==$ ){
?????????????????? $ StrGroup. = $ arryData [$ j];
?????????????? } Else {
?????????????????? $ StrGroup. = $ arryData [$ j]. ","; ???
?????????????? }
??????????? }

?

?????????? $ StartIndex = $ endIndex;

???????? Echo? "No.". $ I. "group data:". $ strGroup ;?

}
