Need help with a while statement

ShadowSlider

Hey,

I probably didnt word the title as good/accurately as I could have but I dont know of anyother way so ill try an elaborate more. I am trying to make a loop that sorts out an array that contains 5 sets of data, each set is similar in makeup but contains different info.

Here is the code im currently using

      //Assign ID's
      if(ereg("<--StartId-->(.*)<--EndId-->", $Pieces[1], $Id))
        {
          $Id[1] = htmlspecialchars(strip_tags($Id[1]));
          echo $Id[1];
        }
      else
        {
          return "Error : Could not find User Id!";
        }

the $Pieces variable is the array containing the 5 sets of data, I am trying to run the above code thru a loop 5 times each time incrementing the array values by 1, I thought that this coude would do the trick but it didnt (to give you a better idea of what im talking about)

$Limit=5;
$i=1;
  while($i < $Limit)
    {
//Assign ID's
      if(ereg("<--StartId-->(.*)<--EndId-->", $Pieces[$i], $Id))
        {
          $Id[$i] = htmlspecialchars(strip_tags($Id[$i]));
          echo $Id[$i];
        }
      else
        {
          return "Error : Could not find User Id!";
        }
       $i++;
    }

Hope that made it clearer, im very tired right now so I dunno how clear I was, but the above code doesnt work 'as it should', if anyone knows what im rambling about and would take the time to help me I really apprecaite your help, thanks in advance as I probably wont be replying for about 12 hours (tommorow is my first day off in 4 weeks and im sleepin in =) )

Can't understand the question, sorry. Could you provide an example of what the array looks like and what you want to output?

Yea figured, I dont need any help on anything other than makeing the variables
$Pieces[] and $Id[] where the [] contains a number 1-5 change number when $i is incremented. So the first time the loop runs they will be $Pieces[1] $Id[1] the next time they will be $Pieces[2] $id[2] until they hit 5. I tried making them $pieces[$i] etc but that didnt work, how would I go about doing this, just kinda forget everything else I said in the first post lol.

I would do something like:

for($i = 1; $i < 5; $i++){
if(ereg("<--StartId-->(.*)<--EndId-->", $Pieces[$i], $Id))
        {
          $Id[$i] = htmlspecialchars(strip_tags($Id[$i]));
          echo $Id[$i];
        }
      else
        {
          return "Error : Could not find User Id!";
        } 
}

Although I have a feeling it's erroring out because $Pieces and $Id are zero based indexes. If that's the case, you would need to do:

for($i = 0; $i < 4; $i++){

Arg, I seem to have run into another problem, the reason why it wasnt working is because it would appear that only the [1] variables are getting assigned information, the loop works though as it puts out the [1] info...ill try and sort out why its not working. I am using this code to pull my myspace source code and take out the comments and stuff cuz im going to be making my own version of my myspace, when a user visits my profil they are redirected to my own site which pulls the info that I want off of my page...if that makes sense, The code is rather large so I wont post it up but thats what im using it for incase anyone was wondering.
