PHP skip through file under certain conditions

Here's an example of my situation:

<?php
if(//condition)
{
   //start output buffer
}
else
{
   //skip through file until POINT A
}
?>
<!-- some nice html, no php here -->
<?php
  //close output buffer & write it to a file
  //POINT A << SKIP TO HERE
?>

Basically, I'm loading the HTML code after the PHP code block into an output buffer. My conditional checks if the file that the output buffer writes to exists. If it exists, I just want to skip past the HTML and the output buffer writing, and start off at POINT A. I would do an exit; but I have more code I wish to output after POINT A.

Any help?

if (/* condition */) {
    //start output buffer
    <!-- some nice html, no php here -->
    //close output buffer & write it to a file
}

You might also want to organize your code into functions, possibly separate files and possibly even classes.

Actually though, if all you're doing is output static HTML into a file, you can skip the whole output-buffer-file-writing procedure and just create a separate static HTML file, full stop. Possibly use include 'file.html' if you want to show it on this page as well.

  1. Enclose the code in conditional blocks.
  2. If doing 1. gives a too complicated structure consider using flags. $doPrintSectionA = false; And checking that flag before you print some section.
  3. If you have PHP >= 5.3 you can use the goto statement.

Note that opening and closing PHP tags doesn't affect the control structures. Ex.:

<?php
if(rand(0,1)){
?>

<b>Hello World!</b>

<?php
}
?>

And a final warning:

You certainly can "goto a:" in the script if you're using PHP 5.3 - http://us.php.net/manual/en/control-structures.goto.php

Use goto's and huge if statements though, and you'll end up with some pretty gnarly code. Here's what I would suggest for a start.

<?php
if(//condition)
{
   //start output buffer
   include "content/page.html";
  //close output buffer & write it to a file
}

//POINT A 
?>
