Internal Server Error on PHP 5.2.8

[GoogleCodeExporter]

An internal server error is produced when am trying to generate the PDF .
This error occurred when my host upgraded from php 5.2.6 to php 5.2.8 

I tried searching the net for a solution , but it looks like it is a common
bug . Please help me finding a solution to this as it is an important
requirement in our web applications

Am using Linux shared host

Running on PHP 5.2.9 here, Linux VPS, no problems. Tell your host to upgrade to 
the
latest version of PHP first... IMO.

If you run DOMPDF from the command line you should see a segmentation fault. I 
have yet to track down the 
source, but I have found that some HTML documents that cause this issue can 
still present problems on updated 
systems (memory limit issues). May or may not be related.

I'm having the same issue.  Dompdf is working fine on my localhost but when I 
run the script on my server (Linux shared hosting from GoDaddy) I get this 
error:
-------
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to 
complete your request.

Please contact the server administrator, support@supportwebsite.com and inform 
them of the time the error occurred, and anything you might have done that may 
have caused the error.

More information about this error may be available in the server error log.

GoDaddy says my version of PHP is 5.x

Looking back at this error we'll need more information about what's going on. 
An internal server error could be due to something as simple as going over the 
allowable memory usage. If you look at the Apache/PHP error logs do you see any 
relevant information?

Having the same issue. Stuck on GoDaddy and I do not have the option to switch 
or upgrade PHP versions. I've upped the memory and time limits to no avail. 

Smaller PDF's are generated easily however the large PDF's that used to work 
fine, now result in a 500 internal server error after 15-20 seconds of 
processing time.

Everything runs smoothly until $dompdf->render(); is called.

Any ideas appreciated.

There does appear to be an issue with PHP 5.2.8 that does not appear in other 
releases. I haven't definitively identified the source (possible memory leak?).

I think the problem stems from the php evaluator class. On newer versions of 
PHP a segmentation fault occurs when using inline php. When disabling 
utf8_decode of the inline php the segmentation fault disappears.

Same here with PHP 5.3.2
Seems that the proposed solution provided by #9 solves the problem.

Same here. PHP 5.3.2 (ubuntu with Suhosin)

Gives segfault when trying to convert pages from "Samples".
All the pages that fail have script type="text/php" in them.

Tried with both 0.6.0b1 and with 0.5.1

When php code is removed PDF generates successfully.

Get this error when converting pages with tables. most samples work fine, have 
an issue with latin1.html. Gives Internal Server Error.

Not sure how to deal with it. Works well with my hostgator account. Godaddy 
server has an issue.

Any one can help?

Issue 46 has been merged into this issue.

With PHP 5.1.6 I get this error on the latin1 example page as mentioned by #12 

It also happens on one of my scripts once a simple table is a certain way down 
the page inside a body element and after about 2 DIVs.

Upgrading from PHP 5.1.6 to 5.3.5 solved the issue for me.

I have this same problem with script type="text/php" began after the updating 
of some packages (unfortunately I noticed not immediately) in March 2011. There 
were errors "segmentation fault"... Before all worked fine. WTF...
Earned today after the upgrade my Ubuntu from 10.04 to 10.10 :)

I have same problem. Working one day and no working the next.  Removing 
php/text script allows to work without problems. Ubuntu 10.04, php -v 5.3.2.  
Has anyone found a work around for this.  I see one guy upgraded to 5.3.5, has 
that worked for anyone else?

Hello, what version of dompdf do you use?
Could you try something to know where this error comes from ?

 - Change the "type" attribute of the inline PHP script from "text/php" to "text/dompdf"
 - Replace "text/php" to "text/dompdf" in renderer.cls.php

and tell me if it works now.

I am using PHP 5.2.14 on godaddy and it seems that there is a big issue with 
dompdf.
It generates one page pdf. But when we try to generate multipage pdf it show 
500 internal server error. This happens when render is called. I don't think 
it's an issue of PHP but for dompdf library itself.

Do you use inline PHP script or long HTML tables ?

I have a strange situation.
I have two sites, both on the same server, thus with the same configuration and 
both with the same version of dompdf (0.6 beta 2) and with the same PHP script.
So, everything works fine on one site, but on the other one I get "internal 
server error".
How is it possible?

This is the server configuration:
Apache version     2.2.17
PHP version     5.3.6
MySQL version     5.1.56
Architecture     i686
Operating system     linux
Kernel version 2.6.38.2-xxxx-std-ipv6-32

Thanks

Are you copying dompdf from one server to the other? Have you installed any 
fonts? A 500 error is a script error, so look in the PHP error log for hints as 
to what's going wrong.

Ubuntu 10.04 LTS (Lucid)
PHP Version 5.3.2-1ubuntu4.10

Pages with script type="text/php" failed. The page was a blank screen. The 
error logs showed a Segmentation Fault. Removing script tags allowed the PDFs 
to generate normally.

From comment #11 I attempted the text/dompdf fix. No help. Went back to text/php

From comment #9 removing utf8_decode fixes the problem.

dompdf/include/php_evaluator.cls.php

Old line 66:
eval(utf8_decode($code));

Changed to 66, 67:
// eval(utf8_decode($code)); 
eval($code);

No, still not working :(

This happens for the memory limit of server and the maximun execution time.
There's that increase these, for example:

ini_set("memory_limit", "999M");
ini_set("max_execution_time", "999");

Do this before you instantiate the class, $dompdf = new DOMPDF();

Sorry for my English!

I have similar problem in Ubuntu w/ php 5.3.2 

None of the above fixes work.  Nothing shows up on my Apache or PHP error logs. 
 Not sure how to debug.

A sample file that gives this (with all the CSS) would help.

Original comment by fabien.menager on 26 Mar 2012 at 6:09

The next release of dompdf will modify the eval(utf8_decode($code)) line that 
appears to be causing some problems. If you're experiencing issues, and are 
using inline script, can you test this out on your own system?
