I've got a little PHP script that generates charts, that has been
working perfectly every day for the past couple years. Since upgrading
the Xserve's PHP from 5.1.6 to 5.2.2 (both Entropy), it has stopped
working. Specifically, it doesn't return any GIFs (charts). Actually, it
will output a GIF providing that session_start() isn't called at the
beginning of chart.php. The reason session_start() is called is that the
data needed by chart.php resides as session variables—so the session
needs to be propogated to chart.php when it's called.
My gut feeling is that *something* in chart.php is now throwing a notice
or warning or something, and that is corrupting the GIF file (which
returns as a broken icon). Here's the beginning of chart.php, which as I
mentioned, was working perfectly verbatim up until last week:
<?php
session_start();
error_reporting(0);
header("Content-type: image/gif");
[...]
Here is a modified version of the above, based on comments I've gleaned
from various forums. (It still doesn't work, btw.)
<?php
@session_start();
@set_time_limit(0);
@error_reporting(0);
// session_start();
header("Content-type: image/gif");
header("Cache-Control: cache, must-revalidate");
header("Pragma: public");
[...]
...Rene
Maybe see if display_errors is on, if so, ini_set('display_errors', 0); might help
but what you might want to do is turn on everything for error reporting and view the page with the
gif output part disabled and see what it says.
<?php
error_reporting(E_ALL);
ini_set('display_errors', 'On');
...
now browse to the page and see what it says. Make sure you comment out the header part that sends a
custom Content-type also.
