Here is my first bug report ever, so please don't be so rude if I forgot something or reported something already known :)

When I first use the function substr() to extract the first chars from the beginning of a large string (around 50 kb) that is a HTML page and when I print the whole string the script seems to stop. In example, I have a script that has basically this calls:

  printpage();
  debuginfo();

Into printpage() is located the substr(); substr() is conditioned by an "if" condition, so is not used every time; if it is used then debuginfo() is not called or prints only few lines of debug, depending of the size of the string that was "substr()ed". My personal workaround is like

  $debugstr=debuginfo();
  $htmlpage=printpage();
  $finalpage=$htmlpage.$debugstr;
  print $finalpage;

this works, but is not so elegant.
Hope you can solve this :)
