PHP alike function "explode"

[Rimantas Petrauskas]

Hi,

does anyone can help me? I need PHP alike "explode" function, but it seems in MQL4 you can not return an array as a function result.

void StringExplode(string sDelimiter, string sExplode, string &sReturn[]){
   
   int ilBegin = -1,ilEnd = 0;
   int ilElement=0;

      ilEnd = StringFind(sExplode, sDelimiter, ilBegin+1);
      ArrayResize(sReturn,ilElement+1);
      sReturn[ilElement] = "";     
      if (ilEnd == -1){
         if (ilBegin+1 != StringLen(sExplode)){
            sReturn[ilElement] = StringSubstr(sExplode, ilBegin+1, StringLen(sExplode));
