PHP dies when you use imagecreatefromjpeg()

[comp.lang.php]

PHP version 4.3.9
GD version 2.0.2

Whenever I use imagecreatefrom jpeg(), PHP completely dies. No errors,
no warnings, no notices, it dies in the following manner:

If using Firefox it just stops running cold
If using Konqueror you get the message "An error occurred while
processing http://www.blah.com/tools/app"

I can't get any more information than that. Has anyone run into this
before?

Thanx
Phil

Not had this problem before and I've used it on Macs and PC's on most
browsers.

Does it do the same with imagecreatefrom gif() ?

Maybe send you code for someone on here to check...

Thanks,

Hi Phil,

If you want to debug imagecreation scripts, you need some way to get to the
errors.
If you have a PHP script that returns an image (content-type: image/png etc
etc) I found the easiest way to change the header of that script into
text/html, in that way if you call the script directly, you'll see the
errors.
Of course, you can also let PHP log errors (from php.ini) and find them in
the logfile.
In both cases, make sure you have errorreporting on, to E_ALL & E_STRICT

Hope that helps.

Sorry I did all of that, including putting the line
error_reporting (E_ALL & E_STRICT) right before the
imagecreatefrom jpeg() functional command, to no avail.

Furthermore, nothing noted in the error logs in php nor httpd. Here is
the code:

// ATTEMPT TO CREATE IMAGE OBJECT BASED UPON PHP GD FUNCTION CALL
BASED ON IMAGE MIME TYPE
if ($this->isSuccessful ) {
$func = $functionArray[$type];
if ((int)$willDown load === 1) {
//eval('$image = $func("$tmpImag eDownloadDir/" .
$this->fileName);') ; // CREATE IMAGE OBJECT FROM TEMP DIRECTORY
$image = imagecreatefrom jpeg("$tmpImage DownloadDir/"
.. $this->fileName);
} else {
//eval('$image = $func("$locatio nPath/" . $this->fileName);') ; //
CREATE IMAGE OBJECT OF APPROPRIATE MIME TYPE
$image = imagecreatefrom jpeg("$location Path/" .
$this->fileName);
}

I checked and the image exists, the file directories exist, and
phpinfo() reveals that GD is enabled.

Ah well you don't want to do that. (E_ALL & E_STRICT) == 0, which
results in no errors reported at all.

You want (E_ALL | E_STRICT).

Thanx, however, that reported nothing either. I might have fixed it,
because in /var/log/httpd Apache logged the error that PHP apparently
could not.

It seems to be a memory limit error; the image was too big to load into
imagecreatefrom jpeg()

Oops, that is what I ment.
SOrry for the confusion. :-)
