I am trying to export a large database via phpMyAdmin. I jeep getting an error that the script stopped because the maximum execution time of 600 seconds was reached (or something like that). I tried setting max_execution_time in php.ini to 0 and -1. The change takes effect as I can see it in phpinfo(), but I am still getting the error. Another strang thing is that originally (before I changed it to 0) it wasn't 600 either. It was 180! Where is this 600 set?
See if it is manually set somewhere. Assuming you are on a UNIX type platform:
find /path/to/root/of/phpmyadmin -name "*.php" -print0 | xargs -0 grep "max_execution_time"
Your web server can have other timeout configurations that may also interrupt PHP execution. Apache has a Timeout directive and IIS has a CGI timeout function. See your web server documentation for specific details.
Don't use phpMyAdmin to import large files. Try using the mysql CLI to import a dump of your DB. Transfer the SQL file to the server and execute the following on the server using PHP script like shell_exec or system
mysql --user=user --password=password database < database_dump.sql.
Of course the database has to exist, and the user you provide should have the necessary privilege(s) to update the database.
PHP by default places resource limits on all php scripts using the following three directives:
=> max_execution_time : Maximum execution time of each script, in seconds (default 30 seconds)
=> max_input_time : Maximum amount of time each script may spend parsing request data (60 seconds)
=> memory_limit : Maximum amount of memory a script may consume (default 8MB)
Your php script was timed out may be because of resource limits. All you need to do is setup a new resource limits so that the script will get executed.
If that doesn't work either,you can set it with set_time_limit(N) function, which sets the time limit in seconds.

I am running some reports and those reports takes more than 300 seconds to execute and finally display on browser.
I have already defined the max execution time in my code and also set the same in php.ini.
ini_set('max_execution_time', 500);
I am using MySQL Workbench to monitor the execution but on 300 sec browser shows
The connection has timed out. The server at localhost is taking too long to
respond.
I just need to extend it to 400-500 sec and all of my reports will start working smoothly.
How can I do that?
Have you tried this:
ini_set('max_execution_time', 0);
This set the maximum execution time to unlimited. You could set this right before calling your report and set it back to a regular value, e.g 300 right after your report is done.
Your web server can have other Timeout configurations settings that may also interrupt PHP execution. Apache has a Timeout Directive which has default value to 300 seconds. Try changing the directive in your conf (httpd.conf for Apache) file.
For more details , See Apache Timeout Directive doc.
This question already has answers here:
ini_set, set_time_limit, (max_execution_time) - not working
(3 answers)
Closed 8 years ago.
I am inserting a huge data values through CSV file via HTML form.
I have used set_time_limit(0); so that script run until the whole operation is not performed.
Fatal error: Maximum execution time of 300 seconds exceeded in
C:\xampp\htdocs\clytics\include\clytics.database.php on line 135
Now, I am trying to catch this fatal error.
I have used set_time_limit(0); so that script run until the whole
operation is not performed.
Probably needs more memory as well. Basically your code is just a hog & you need to tame the way it is gobbling up resources.
But that is just a tangent on the overall architecture issues you might be facing.
Specific to there issue, is there something in your code that would override that value of set_time_limit(0);?
Also, ar you running this script via the command line or the PHP in Apache? Because the CLI config php.ini is 100% different form the Apache module config of php.ini.
For example, on Ubuntu the Apache PHP php.ini is here:
/etc/php5/apache2/php.ini
But the command line (CLI) php.ini is here:
/etc/php5/cli/php.ini
And if you want to brute force your script to eat up memory regardless of your config settings, you can add this to the top of your PHP file:
ini_set('MAX_EXECUTION_TIME', -1);
If one reads up more on set_time_limit this comes up:
Set the number of seconds a script is allowed to run. If this is
reached, the script returns a fatal error. The default limit is 30
seconds or, if it exists, the max_execution_time value defined in the
php.ini.
Then reading up on max_execution_time this comes up:
This sets the maximum time in seconds a script is allowed to run
before it is terminated by the parser. This helps prevent poorly
written scripts from tying up the server. The default setting is 30.
When running PHP from the command line the default setting is 0.
But then, the magic 300 number shows up:
Your web server can have other timeout configurations that may also
interrupt PHP execution. Apache has a Timeout directive and IIS has a
CGI timeout function. Both default to 300 seconds. See your web server
documentation for specific details.
So now you know where the 300 comes from. But doing ini_set('MAX_EXECUTION_TIME', -1); should let you run the script without a timeout.
And final bit of info if none of that somehow works: Look into max_input_time:
This sets the maximum time in seconds a script is allowed to parse
input data, like POST and GET. Timing begins at the moment PHP is
invoked at the server and ends when execution begins.
While max_input_time might not seem to be related, in some versions of PHP, there is a bug where max_input_time and max_execution_time are directly connected.
I am trying to import a large .sql data file using phpMyAdmin in XAMPP. However this is taking a lot of time and I keep getting:
Fatal error: Maximum execution time of 300 seconds exceeded in C:\xampp\phpMyAdmin\libraries\dbi\DBIMysqli.class.php on line 285
And the file is about 1.2 million lines long.
The file is about 30MB big, so it is not that big. I don't really understand why it is taking so long.

The is the config file for php.ini in xampp, for some reason i still get

There's a configuration variable within the phpMyAdmin directory that you can find in phpmyadmin\config.inc.php called $cfg['ExecTimeLimit'] that you can set to whatever maximum execution time you need.
Well, to get rid of this you need to set phpMyadmin variable to either 0 that is unlimited or whichever value in seconds you find suitable for your needs. Or you could always use CLI(command line interface) to not even get such errors(For which you would like to take a look at this link.
Now about the error here, first on the safe side make sure you have set PHP parameters properly so that you can upload large files and can use maximum execution time from that end. If not, go ahead and set below three parameters from php.ini file,
max_execution_time=3000000 (Set this as per your req)
post_max_size=4096M
upload_max_filesize=4096M
Once that's done get back to finding phpMyadmin config file named something like "config.default.php". On XAMPP you will find it under "C:\xampp\phpMyAdmin\libraries" folder. Open the file called config.default.php and set :
$cfg['ExecTimeLimit'] = 0;
Once set, restart your MySQL and Apache and go import your database.
Enjoy... :)
Set Only 3 Parameters from php.ini file of your server
A. max_execution_time = 3000000 (Set as per your requirment)
B. post_max_size = 4096M
C. upload_max_filesize = 4096M
Edit C:\xampp\phpMyAdmin\libraries\config.default.php Page
$cfg['ExecTimeLimit'] = 0;
After all set, restart your server and import again your database.
Done
You're trying to import a huge dataset via a web interface.
By default PHP scripts run in the context of a web server have a maximum execution time limit because you don't want a single errant PHP script tying up the entire server and causing a denial of service.
For that reason your import is failing. PHPMyAdmin is a web application and is hitting the limit imposed by PHP.
You could try raising the limit but that limit exists for a good reason so that's not advisable. Running a script that is going to take a very long time to execute in a web server is a very bad idea.
PHPMyAdmin isn't really intended for heavy duty jobs like this, it's meant for day to day housekeeping tasks and troubleshooting.
Your best option is to use the proper tools for the job, such as the mysql commandline tools. Assuming your file is an SQL dump then you can try running the following from the commandline:
mysql -u(your user name here) -p(your password here) -h(your sql server name here) (db name here) < /path/to/your/sql/dump.sql
Or if you aren't comfortable with commandline tools then something like SQLYog (for Windows), Sequel Pro (for Mac), etc may be more suitable for running an import job
This worked for me.
If you got Maximum execution time 300 exceeded in DBIMysqli.class.php file. Open the following file in text editor
C:\xampp\phpMyAdmin\libraries\config.default.php then
search the following line of code:
$cfg[‘ExecTimeLimit’] = 300;
and change value 300 to 900.
https://surya2in1.wordpress.com/2015/07/28/fatal-error-maximum-execution-time-of-300-seconds-exceeded/
Simply set $cfg['ExecTimeLimit'] = 0; In xampp/phpMyAdmin/libraries/config.default.php.
Maximum execution time in seconds (0 for no limit).
And make this below changes in php.ini file as per file size.
post_max_size = 600M
upload_max_filesize = 500M
max_execution_time = 5000
max_input_time = 5000
memory_limit = 600M
But make sure 'post_max_size' and 'memory_limit' should be more than upload_max_filesize.
**Note - Don't forget to restart your server.
If you are using the laragon and your database is phpMyAdmin the process is the same for tackle this error.
Open laragon right-click on it and open php.ini file
set these value accordingly to your needs
max_execution_time
post_max_size
upload_max_filesize
Open new file config.default.php
path is C:\laragon\etc\apps\phpMyAdmin\libraries\config.default.php
and set the value of this $cfg['ExecTimeLimit'] = 0;
Restart the laragon.
I hope it would solve your problem for laragon environment 🙏 #Happy Coding :)
Is it a .sql file or is it compressed (.zip, .gz, etc)? Compressed formats sometimes require more PHP resources so you could try uncompressing it before uploading.
However, there are other methods you can try also. If you have command-line access, just upload the file and import with the command line client mysql (once at the mysql> prompt, use databasename; then source file.sql).
Otherwise you can use the phpMyAdmin "UploadDir" feature to put the file on the server and have it appear within phpMyAdmin without having to also upload it from your local machine.
This link has information on using UploadDir and this one has some more tips and methods.
you must change php_admin_value max_execution_time in your Alias config (\XAMPP\alias\phpmyadmin.conf)
answer is here:
WAMPServer phpMyadmin Maximum execution time of 360 seconds exceeded
After trying many things with no success, I've managed to get SSH access to the server, and import my 80Mb database with a command line, instead of phpMyAdmin. Here is the command:
mysql -u root -p -D mydatabase -o < mydatabase.sql
It's much easier to import big databases, if you are running xammp on windows, the path for mysql.exe is C:\xampp\mysql\bin\mysql.exe
1-make a search in your local drive and type "php.ini"
2-you may see many files named php.ini you should choose the one that fits with your php version (see localhost)
3-open the php.ini file make a search on "max_execution_time" then make it equal to "-1" to make it unlimited
Never change original config.default.php file.
Changing general executing time in php.ini has no effect on phpmyadmin scripts.
Use a new config.inc.php or the config.sample.inc.php provided in the /phpMyAdmin folder instead.
You can set $cfg[‘ExecTimeLimit’] = 0; means endless execution in the config.inc.php as recommended above. Be aware this is not a "normal" ini file. Its a php script, so you need a open <?php at the beginning of that file.
But most important: Do not use this procedure at all! phpmyadmin is okay for small database but not for huge databases with several MB or GB.
You have other tools on a server to handle the import.
a) If you have a server admin
system like Plesk, use there database import tool.
b) use ssh commands to make database dump or to write databases directly in
mysql via ssh. Commands below.
Create a database dump:
mysqldump DBname --add-drop-table -h DBhostname -u DBusername -pPASSWORD > databasefile.sql
Write a database to mysql:
mysql -h rdbms -u DBusername -pPASSWORD DBname < databasefile.sql
Best solution for this error when i tried some points.
Follow this steps to solve this issue:
locate the file [XAMPP Installation Directory]\php\php.ini (e.g. C:\xampp\php\php.ini)
open php.ini in Notepad or any Text editor
locate the line containing max_execution_time and
increase the value from 30 to some larger number (e.g. set: max_execution_time = 90)
then restart Apache web server from the XAMPP control panel
Changing the max_execution_timeout in php.ini. may help with maximum execution error. but sometimes the database is imported correctly but still it shows maximum execution time error, it can be due to some error of xamp.
I was experiencing the same error even after making all changes in php.ini. which is mentioned above and realized that all the things, tables of database were imported and it was working fine but it was still showing the max_execution_timeout error.
Set Only 3 Parameters from php.ini file of your server
A. max_execution_time = 3000000 (Set as per your requirment)
B. post_max_size = 4096M
C. upload_max_filesize = 4096M
Case 1 : If you are Using Xampp, Edit
C:\xampp\phpMyAdmin\libraries\config.default.php
Case 2 : If you are Using Wampp, Edit
c:\wamp64\apps\phpMyAdmin\libraries\config.default.php
Case 3 : If you are Using Laragon, Edit
C:\laragon\etc\apps\phpMyAdmin\libraries\config.default.php
search for $cfg['ExecTimeLimit'] in config.default.php file and make the following changes
$cfg['ExecTimeLimit'] = 0;
After all set, restart your server and import again your database.
Done
You can increase the limit:
ini_set('max_execution_time', 3000);
(Note that this script can cause high memory usage as well, so you probably have to increase that as well)
Other possible solution: Chunk your sql file, and process it as parts. I assume, it is not one big SQL query, is it?
Update: As #Isaac pointed out, this is about PHPMyAdmin. In this case set max_execution_timeout in php.ini. (The location depends on your environment)
The following might help you:
ini_set('max_execution_time', 100000);
And in your mysql - max_allowed_packet=100M in some cases where queries are too long sql also produce and error "MySQL server has gone away";
Change the values to whatever you need.
I am running a huge import to my database(about 200k records) and I'm having a serious issue with my import script timing out. I used my cell phone as a stop watch and found that it times out at exactly 45 seconds every pass(internal server error)... it only does about 200 records at a time, sometimes less. I scanned my phpinfo() and nothing is set to 45 seconds; so, I am clueless as to why it would be doing this.
My max_execution_time is set to 5 minutes and my max_input_time is set to 60 seconds. I also tried setting set_time_limit(0); ignore_user_abort(1); at the top of my page but it did not work.
It may also be helpful to note that my error file reads: "Premature end of script headers" as the execution error.
Any assistance is greatly appreciated.
I tried all the solutions on this page and, of course, running from the command line:
php -f filename.php
as Brent says is the sensible way round it.
But if you really want to run a script from your browser that keeps timing out after 45 seconds with a 500 internal server error (as I found when rebuilding my phpBB search index) then there's a good chance it's caused by mod_fcgid.
I have a Plesk VPS and I fixed it by editing the file
/etc/httpd/conf.d/fcgid.conf
Specifically, I changed
FcgidIOTimeout 45
to
FcgidIOTimeout 3600
3600 seconds = 1 hour. Should be long enough for most but adjust upwards if required. I saw one example quoting 7200 seconds in there.
Finally, restart Apache to make the new setting active.
apachectl graceful
HTH someone. It's been bugging me for 6 months now!

It's quite possible that you are hitting an enforced resource limit on your server, especially if the server isn't fully under your control.
Assuming it's some type of Linux server, you can see your resource limits with ulimit -a on the command line. ulimit -t will also show you just the limits on cpu time.
If your cpu is limited, you might have to process your import in batches.
First, you should be running the script from the command line if it's going to take a while. At the very least your browser would timeout after 2 minutes if it receives no content.
php -f filename.php
But if you need to run it from the browser, try add header("Content-type: text/html") before the import kicks.
If you are on a shared host, then it's possible there are restrictions on the system when any long running queries and/or scripts are automatically killed after a certain length of time. These restrictions are generally loosened for non-web running scripts. Thus, running it from the command line would help.
The 45 seconds could be a coincidence -- it could be how long it takes for you to reach the memory limit.. increasing the memory limit would be like:
ini_set('memory_limit', '256M');
It could also be the actual db connection that is timing out.. what db server are you using?
For me, mssql times out with an extremely unhelpful error, "Database context changed", after 60 seconds by default. To get around this, you do:
ini_set('mssql.timeout', 60 * 10); // 10 min
First of all
max_input_time and
set_time_limit(0)
will only work with VPS or dedicated servers . Instead of that you can follow some rules to your implementation like below
First read the whole CSV file .
Then grab only 10 entries (rows) or less and make a ajax calls to import in DB
Try to call ajax every time with 10 entries and after that echo out something on browser . In this method your script will never timeout .
Follow the same method untill the CSV rows are finished .
How can I rewrite this into a cron that will run every day for longer than 30 seconds? Also, do I need to edit the .htaccess or php.ini file in the cron.php directory to say something? Over the browser it runs just fine for longer than 30 seconds; over the shell, it runs just fine too. But as a cron set task, it dies after 30 seconds. I'm on 1and1 share hosting.
0 12 * * * php5 /this/is/the/file/cron.php
There are several things that could be terminating your script. One could be the maximum execution time set in the php.ini file. If that's the case, you can override it in your script with set_time_limit(0); where zero means no limit and any number greater than zero is the number of seconds to allow the script to run for before being terminated. It's important to note that this time does NOT include the time it takes for the browser to make the request, so file upload time wouldn't count here.
If you're in a shared hosting environment (like Dreamhost), they have process watches that will kill off any PHP process after a set time limit. You cannot get around these. You would need to contact the hosting provider to see what you need to do to get access to run the script for longer (for Dreamhost, they want you to have a they're PS offering).
Use this syntax to start php:
php -c /path/to/another/php.ini /this/is/the/file/cron.php
Then you can specify a different timeout (or no timeout) in a different php.ini file.
ini_set('max_execution_time', 600);
Add this to the top of your php file and it will run for 600 seconds. Anything more is not recommended but you can have a go if you want.
You don't need to set a higher max_execution_time if you use PHP CLI:
CLI SAPI default value for "max_execution_time" is set to unlimited.
http://nl3.php.net/manual/en/features.commandline.differences.php
I would just use wget http://path.to.myscript.php
If it's dying after 30 you may need to set max_execution_time = 60 in your php.ini to allow the script to run longer than 30 seconds.
You could also use ini_set('max_execution_time', 60)
But as the manual page says, in some cases (i.e. running in safe mode) this will have no effect at all: http://uk.php.net/manual/en/info.configuration.php#ini.max-execution-time
It could also be possible that the php.ini for client line has different max execution values than for the browser. I have seen it sometimes.
