Here is a completely native (without even calling PHP) way of splitting a Long Integer array into a string value. This new method uses the JSON commands that were added in v14:

// Method: UTIL_Split_Array // Parameters // $1 - pointer to the array // $2 - [OPTIONAL] split character // Return // $0 - string of elemets in the array separated by the split character // ---------------------------------------------------------------------- C_POINTER($1;$arr) C_TEXT($0;$2;$split;$result) If (Count parameters>0)    If (Type($1->)=LongInt array)       $arr:=$1       $result:=JSON Stringify array($arr->;*)       If (Count parameters>=2)          $split:=$2       Else          $split:=""       End if       $result:=Replace string($result;"[\n\t";"") // start of json object       $result:=Replace string($result;"\n]";"") // end of json object       $result:=Replace string($result;",\n\t";$split) // split each element       $0:=$result    End if End if

If this method is saved in your dayabase as UTIL_Split_Array it can then be used like this:

ARRAY LONGINT($arr;3) $arr{1}:=1 $arr{2}:=2 $arr{3}:=3 $test:=UTIL_Split_array (->$arr;",")

The code above would return 1,2,3

You can also use this method like this:

ARRAY LONGINT($arr;3) $arr{1}:=1 $arr{2}:=2 $arr{3}:=3 $test:=UTIL_Split_array (->$arr)

The code above would return 123
