$string containing code

[Michan]

Hi there,

I'm trying to create a $string to bring up multiple times later. It contains code, and I can't figure out how to do it.

The string is:

[code]$string {

echo ('|');

for($i = 0; $i < sizeof($game); $i++)
{
echo ($game[$i].'|');
}

echo ('|');

}[/code]

Is there a special way to do this for strings that are more than just text that needs reproducing?

Many thanks,
- Mi

if you want to add things to a string you would do like so.

[code]<?
$string = "";
$string .= '|';
for($i = 0; $i < sizeof($game); $i++)
{
$string .= $game[$i].'|';
}

$string .= '|';
echo $string;
?>[/code]

craygo there's really no reason to initialize as an empty string just to turn around and append a '|' character to it. Also you'll end up with two '|'s at the end the way you wrote it (which may or may not be the way you intended it...it just didn't seem likely that you would want it that way).

[code]<?php
$string = "|";
for ($i = 0, $game_size = sizeof($game); $i < $game_size; $i++) $string .= $game[$i] . "|";
echo $string;
?>[/code]

Setting $game's size to a temporary variable instead of checking $i vs sizeof($game) each loop will speed up your script significantly. Also you don't [i]need[/i] to use braces {} unless you have more than one statement.

However it appears to me that what Michan is [i]wanting[/i] to do is create a function like this:

[code]<?php
function print_game() {
  $game_size = sizeof($game);
  if (!$game_size) return false;
  $string = "|";
  for ($i = 0; $i < $game_size; $i++) $string .= $game[$i] . "|";
  echo $string;
  return $string;
  }
?>[/code]

Then you can call [color=green]print_game()[/color] in your script and it will echo $game's contents to the screen as well as returning the string that was printed, or false if $game hasn't been set yet.

I didn't write it he did. If he wants 2 "|" at the end up to him. I just gave him something to start with. Figured if it was going to contain code somewhere on his page might start it off blank. But whatever.

Sorry Craygo, that was my mistake; I noticed it when I was outputting your code, though :)

Thanks for these examples, you're both life savers. They function perfectly.

Kindest regards.

I noticed that so I tried to clarify that you [i]both[/i] put two '|'s at the end which I suspected wasn't how he wanted. ;)

I'm glad we were able to help you sort this out Michan! :)
