do inside a variable

Cwin

Is there any way to put a do{} inside a variable?
Like:

$x = do {echo "something";} while ($y==1);

i know that doesn't work, but is there any way to make it work?

Why...

<?php
   function cwinsfunc($arg) {
   //This is where there is some code
   $x = 1;
   return <<<EOF
      This is a load of HTML<br>
      PHP will only replace variables, nothing else<br>
      echo ("hi") will return echo ("hi")<br>
      $x will return 1<br>
      <b>Bold Text</b><br>
      <br>
      So obviously i cant put a do in here
   EOF;
}

Why do you want to?

(PS; you might want to look at eval()).

what i want to do:

In that function i posted, i want to have a bit that repeats while something = something. That will require a do/while. I cant put do/while in the bit under return<<<EOF

Try it yourself

I can put variables though

So i wanted a variable that when it is set, it does the do/while bit, then it assigns the result to the variable. So to get what it returned, all i have to do is type $variable in the code.

I checked, functions dont work in there either.

I think you will just have to build up the string and return it.

function whatever()
{
  $str = "Header Line\n";
  for(%i = 0; $i < 3; $i++)
  {
    $str .= "Line $3\n";
  }
  return $str;
}

I know this can get a bit ugly when generating a bunch of html output. One other alternative is to use the ob_ functions and grab the output buffer.
