Somewhere in my PHP script, a call to ob_start()
is issued, and I am trying to find where exactly. To do this, I use xdebug, and proceed by dichotomy, calling ob_get_contents()
which returns FALSE as long as ob_start()
hasn't been called.
I have narrowed my code to:
<?php
...
if ( ob_get_contents() ) { xdebug_break(); }
require_once( 'lib/local.php' );
if ( ob_get_contents() ) { xdebug_break(); }
...
?>
lib/local.php
is a local, writeable file that contains nothing else than defines.
Now the funny part is this: if I replace require_once( 'lib/local.php' )
with the contents of lib/local.php
, the second ob_get_contents()
returns FALSE, as expected.
Now I am really puzzled at what's going on here. Insight, anyone?
