Fatal error: Maximum execution time of 30 seconds exceeded

When PHP is processing a file upload and you receive the error message “Fatal error: Maximum execution time of 30 seconds exceeded” it is because the script has timed out. I was working on an application where this was occuring during a file upload. The entire file would be uploaded, then the error would be displayed

Various websites instruct you to call set_time_limit() on the upload page. This overrides the max_execution_time setting which is found in php.ini. Calling this function on my upload page seems to have no effect on my server.  Changing max_execution_time in php.ini to 0 is supposed to be an unlimited timeout. However i was still receiving the error message. It would say “Fatal error: Maximum execution time of 0 seconds exceeded” which does not make any sense to me at all.

I discovered that, in addition to max_execution_time there is an additional setting max_input_time which controls how long a php file can spend processing the request data.  When i set max_input_time to a higher value, the problem goes away. So, it appears that the error message is reporting the wrong configuration variable.

These settings are found in php.ini, however depending on your host you may be able to override them either in your script or in an .htaccess file.   After you update php.ini you may have to restart your https server process to reload the php settings.  (windows servers may need to recycle the application pool).

This is really helpful… and I know I’m going to sound very ‘green’ when I say this… but how can I edit the ‘max_execution_time’? I have no idea what ‘php.nin’ is exactly. :(

Hi Olivia – php.ini is the global configuration file for PHP. Depending whether you are running on your own computer or a shared web host account, you may or not have access to change that file.

You can read more about it on the php site –

You might want to take a look at some existing PHP software to see how this is handled. I would recommend downloading a copy of the Joomla 1.1.x release along with the Docman or Repository components. Both allow the uoload and download of large files, especially Docman which is often used to handle the downloading and uploading of large PDF files.

October 15, 2007 at 10:31 pm

Hey Esra, Thanks for the Docman tip, I checked that out. Technically, you could still get this same execution error with those components because they still depend on the php ini settings. You can override ini settings in your php code using ini_set, which is what most upload/download components do. However you’ll run into a host once in a while that doesn’t allow it. Most decent hosts do, though.

I have change php.ini in C:/Windows like this.. “max_execution_time = 600 ; Maximum execution time of each script, in seconds”, but i still have the problem Fatal error: Maximum execution time of 30 seconds exceeded in C:\AppServ\www\diky\log_dndb\cari_dataesn_vcr.php on line 58.

June 7, 2008 at 9:06 am

Guys, I have the answer..
I put the script like this..
//set time limit 180 seconds

in my script, it can work to run query more than 30 seconds.and the result..
“Time to query : 43.066 seconds.”..
Thx to all..

“i set max_input_time to a higher value in my php.ini file” but if i m using only few php pages then how i can fix this problem by the coading.

Plz Reply

Thank you so much for posting this solution.

March 29, 2009 at 4:08 am

simple follow this instruction: (why people always give hard instruction to others?)

1) Open your notepad. and paste this code:

max_execution_time = 120
max_input_time = 120

2) Save it as php.ini

3) Upload the file using FTP/Cpanel and Put in /administrator folder (joomla direcory)

4) DONE! Now you can install any files without having the message Fatal error: Maximum execution time of 30 seconds exceeded bla bla bla bla..

thanks arafat. sometimes when I have a technical problem, I’m not really interested in the details and i just want my problem fixed. I understand what you are saying that instructions are often overly complicated. unfortunately it is not usually possible to give exact instructions unless everybody is using the exact same server setup. my instructions are purposely “generic” so that people reading will understand the problem and then they can fix it on their machine – even though their setup is probably slightly different than mine.

i’m sure your instructions work perfectly on your host, but that is not a standard location for php.ini – I’m guessing it is specific to CPanel or Joomla or even your particular host. also, i would strongly advice against overwriting your existing php.ini file because there are many more settings in that file and overwriting the file would blow away any existing php configuration settings. it would be better to open the file and edit only the lines that are relevant.

i m also facing same problem
Fatal error: Maximum execution time of 30 seconds exceeded in c:\apache\htdocs\ims\process.php on line 42

and at line 42 i have this statement
i read all your comments and other suggestions but i am not able to find “php.ini”,max_execution_time,max_input_time,etc
thanks ..

June 4, 2009 at 6:20 am

excellent the parameters retrned were really misleading, but this directive has solved the problem immediately

August 9, 2009 at 5:56 am

Great Thans alot

I changed both
max_execution_time = 600;
max_input_time = 600;
I have 11 MB file to download, I calculated the time for downloading it, and changed accordingly. But if the file size differs may be 100 MB, 200 MB, 750 MB then how much value need to place in

How I can fast up the downloading speed?
Do you have any efficient PHP downloading script? If so please send me.

Once again Thanks for you help

August 11, 2009 at 3:49 pm

Hey Umar, the execution time is affected by the connection speed of your visitor, so there is no fixed number. You could probably calculate it based on a reasonable connection speed and then set your server limits with a conservative value.

i Have problem same like above but the diff is that i am trying to deleting 987900 from the database but in one time i can delete only 780 or 785. how can i delete the whole record

February 3, 2010 at 1:42 pm

The problem is not really with deleting, but just the script is taking too long to run. You either have to bump up the PHP limits or think of another way to accomplish that same thing. Maybe a queue or use ajax to do it in batches?

April 8, 2010 at 1:58 am

you can add this script in your php code..

set_time_limit(180);//set limit to running maks 180 seconds

April 21, 2010 at 4:55 pm

hi all, i had a similar problem. it was resolved by the follwing setting:

max_execution_time = 180
max_input_time = 180

Make sure that the execution time and input time is either the same or the input time should be double the execution time and not the other way around ie:

max_execution_time = 60
max_input_time = 120

I hope you finds this helpful. it really helped me :0

July 21, 2010 at 4:05 pm

thx so much for information…

December 4, 2010 at 2:47 am

You can also use this set_time_limit(0),Pass the zero,it will run until ur job not done.

I have this problem Fatal error: Maximum execution time of 90 seconds exceeded in \\boswinfs04\home\users\web\b2844\whl.kellc\shopping\catalog\model\tool\image.php on line 4
, and I looked at php.ini setting below.

magic_quotes_gpc = Off;
register_globals = Off;
default_charset = UTF-8;
memory_limit = 64M;
max_execution_time = 18000;
upload_max_filesize = 999M;
safe_mode = Off;
mysql.connect_timeout = 20;
session.use_cookies = On;
session.use_trans_sid = Off;
session.gc_maxlifetime = 12000000;
allow_url_fopen = on;

I am little confused but it seems I need to add like this below.

magic_quotes_gpc = Off;
register_globals = Off;
default_charset = UTF-8;
memory_limit = 64M;
max_execution_time = 18000;
max_input_time = 18000;
upload_max_filesize = 999M;
safe_mode = Off;
mysql.connect_timeout = 20;
session.use_cookies = On;
session.use_trans_sid = Off;
session.gc_maxlifetime = 12000000;
allow_url_fopen = on;

So is 18000 is better or should be less? I saw it Nelesh mentioned set_time_limit(0), sorry I am still learning on this part.

@joren you are the best!

I resolved my problem

Brilliant fix. Thank you!.

December 7, 2011 at 4:45 pm

Interesting post.
For a couple of solutions of the original problem (exceeding execution time), use set_time_limit() function or change php.ini configuration file.
You can find out how here: PHP time limit

Hi i have taken windows shared hosting and when i added plugin it says Fatal error: Maximum execution time of 30 seconds exceeded.As i contact to hosting provider they said they will not increase execution time more that 30 please tell me to add some code in wordpress config so i can proceed.

January 20, 2012 at 4:31 am

If the host doesn’t allow you to override the execution time setting then your only choice is to get a new host. But, on shared hosting they will almost always set certain limits to prevent one single customer from hogging all the server resources.

February 17, 2012 at 8:40 am

work like charm.. thanks mate

March 2, 2012 at 8:34 am

If you are running xampp then in phpMyAdmin folder open (config.default.php) file
and set variable ($cfg[‘ExecTimeLimit’]) value to 0.

It runs for me in xampp.

whether you export/import db or executing query via php

I had the same problem.

Thanks for help

September 3, 2013 at 11:54 am

Thanks a lot for this post, solved my problem :)

November 15, 2013 at 1:28 pm

what if the other side, the webservice where the page is conecting to is down?
The adjustment won’t help much.
How can you handle that message and print something more elegant??

Best Regards

November 15, 2013 at 1:49 pm

If you’re page is timing out due to a third-party API then you would want to set some type of timeout in your code when you make the call, then you could handle it in some other way – showing a more friendly message for example

April 24, 2014 at 3:43 am

Hey. Thanx for your solution to fix this problem but i cant find the php.ini file. Im using WampServer Plz help me

May 11, 2014 at 2:24 pm

I don’t use Wamp – you probably can go to the Wamp support forums and ask for the location of php.ini

May 10, 2014 at 9:40 pm

I usually set max_execution_time on each php script. But recently I often put it in php.ini. Until now I did not know which the best way.

May 11, 2014 at 2:23 pm

It’s probably best to set the max execution time in php.ini to a reasonable level – and then override the setting on any page that needs an extra long execution time (like a page for large file uploads). One some servers you can also override that setting in an .htaccess file so it only applies to one folder.

Depending on the server configuration though sometimes you are not permitted to override that setting.
