Phpinfo() Disabling Can Break Scripts

Recommended Posts

I just spent an entire 12 hour work day trying to figure out what was breaking my photo uploads only to find that phpinfo() was disabled and the script was calling on it to determine the gd status.

 

As a heads up to others, if you're experiencing problems check your upload or other scripts that might be calling on this function.

 

As a note to TCH, please, please, please start notifying us of these changes (no matter how small they may seem). It may seem that the only consequence of disabling phpinfo() is not being able to pull up the info page but for those of us using extensive scripting, changes such as this can wreak havoc on our sites causing us to try to track down a problem that we should have been informed of in the first place.

 

A new forum or extensive thread announcing changes (the seemingly "little ones") seems like a great idea, giving us a reference to check changes so we can save time trying to figure out for ourselves why things aren't working.

 

Thanks for the ears.

I'm just curious what script broke, whether it was one other customers may have or one you wrote yourself.

 

The reason I ask is twofold. The first is so others can know it may become a problem for them and the other is to see what non-standard scripts are out there in common use. I'm no PHP pro but it seems the "normal" way to check to see if gd is loaded is to use

>if(extension_loaded("gd"))

Maybe you could incorporate this into your script instead of trying to parse phpinfo?

 

Hope it helps.

It's a pretty common check for the gd version found in image upload scripts:

 

function checkgd(){

$gd2="";

ob_start();

phpinfo(8);

$phpinfo=ob_get_contents();

ob_end_clean();

$phpinfo=strip_tags($phpinfo);

$phpinfo=stristr($phpinfo,"gd version");

$phpinfo=stristr($phpinfo,"version");

preg_match('/\d/',$phpinfo,$gd);

if ($gd[0]=='2'){$gd2="yes";}

return $gd2;

}

 

Thanks for the alternate means, but, honestly, it was no problem for me to find a solution once I knew phpinfo() had been disabled. The problem is that I spent 12 hours trying to find the source of the problem because no one informed me that the function was no longer available. This has happened more than once that I've had to spend entire days tracking down a problem that could have been prevented had a change been widely announced. Can we please have some sort of announcement system for minor changes? I'm subscribed to everything I know of but critical information is being missed and I simply can't afford any more days like this. I'm pooped!

I just saw that info in the link you sent, so my bad for missing that.

 

Have there been any changes in our ability to modify settings for php.ini via .htacess? Scripts that ran perfectly before (after my own modifications) are now timing out big time and I have to keep refreshing the page over and over and over again until they complete.

I do image uploading in the guestbook script I maintain but the script just uses

 

if (is_function(imagejpeg))

 

to see if GD is installed when making thumbnails. But as Jim says using extension_loaded('GD') would seem a far better method of checking if it is installed not to mention less cpu intensive as parsing the phpinfo().
