Unexpected Results

[Novo]

PHP Code:

function onCreated()
  {
  this.string = new TStaticVar();
  this.string.n.one = 1;
  this.string.n.two = 2;
  
  temp.arr = this.string.savevarstoarray(0);
  for ( a: temp.arr )
    if ( contains( a, b ) )
      echo( a );
  } 


When b = "two": n.two=2
When b = "n": n.two=2,n.one=1
When b = "one": n.one=1

When b = "t": ... Nothing.
When b = "o": ... Nothing.
When b = "n.": ... Nothing.
When b = "=": ... Nothing.

When b = "1": n.one=1

Summary:
When using the 'contains' function, the results vary. By deduction, we can see that if a string contains "two", than it must contain "t", however... It returns false.

It seems like the string is split by symbols ( ., =, " ", etc etc ) and then they are compared token[x] == needle.

Working Version:

PHP Code:

function contains( haystack, needle )
  {
  if ( haystack.type() == 2 )
    return false;
  
  for ( i = 0; i =< haystack.length() - needle.length(); i ++ )
    {
    if ( haystack.substring( i, needle.length() ) == needle )
      return true;
    }

  return false;
  }

Thinking about it... contains is probably for arrays... If that's the case, I guess the results would be a little more expected...

But -- If that's the case: would there be a 'contains' for strings?

Yes contains() is for arrays I believe.

I think you can use haystack.pos(needle) >= -1 to check for an occurence in a string.

Contains() is checking for substrings which are enclosed with one of those characters:
".,;:-_><|!\"$%&/\\()=?`{[]}+*~#''^ "

Example: contains("hello you","you") = true
The text "two" is not containing a word "t"
