"Reversing" Arrays

Hrm, is there a function that reverses a array?
like
this.array[ 0 ] = 2;
this.array[ 1 ] = 3;
this.array[ 2 ] = 1;

now this.array.reverse(); or something like this would make

this.array[ 0 ] == 1;
this.array[ 1 ] == 3;
this.array[ 2 ] == 2;

Can I ask why you would want to do this?

PHP Code:


		
			
  temp.myArray = {3, 5, "test"};

  for (temp.curPar = (temp.myArray.size() - 1); temp.curPar > -1; temp.curPar--)

  {

    temp.newArray.add(temp.myArray[temp.curPar]);

  }

  echo(temp.newArray);

You should check the wiki more often.

There is not (yet). We could add a few more string and array operators if wanted though.

Go to for example the clientside scripting page, CTRL + F and type in what you are looking for. Voilá, check mate.

Some string functions I use sometimes.

ReverseArray:

PHP Code:


		
			
public function reversearray(temp.array) {

  temp.newarray;

  temp.i;

  

  newarray = "";

  for (i = array.size() - 1; i > -1; i --) {

    newarray.add(array[i]);

  }

  return newarray;

}

ReverseString:

PHP Code:


		
			
public function reversestring(temp.string) {

  temp.i;

  temp.out;

  

  for (i = string.length() - 1; i > -1; i --) {

    out @= string.charat(i);

  }

  return out; 

}

ReplaceSubString:

PHP Code:


		
			
public function replacesubstring(temp.string, temp.position, temp.length, temp.newstring) {

  temp.stringa;

  temp.stringb;

  temp.outstring;

  

  if (position < 0) {

    return;

  }

  stringa = string.substring(0, position);

  stringb = string.substring(position + length, -1);

  outstring = stringa @ newstring @ stringb;

  return outstring;

}
