致命错误: 最长执行时间超过300秒

Try something like the following in your script:

set_time_limit(1200);

At the beginning of your script you can add.

ini_set('MAX_EXECUTION_TIME', '-1');

PHP's CLI's default execution time is infinite.

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.

http://gr.php.net/manual/en/info.configuration.php#ini.max-execution-time

Check if you're running PHP in safe mode, because it ignores all time exec settings when on that.

I encountered a similar situation, and it turns out that Codeigniter (the PHP framework I was using) actually sets its own time limit:

In system/core/Codeigniter.php, line 106 in version 2.1.3 the following appears:

if (function_exists("set_time_limit") == TRUE AND @ini_get("safe_mode") == 0)
{
@set_time_limit(300);
}

As there was no other way to avoid changing the core file, I removed it so as to allow configuration through php.ini, as well as give the infinite maximum execution time for a CLI request.

I recommend recording this change somewhere in the case of future CI version upgrades however.

If you are using WAMP Go to :

Increase the max_execution_time in php.ini then go to

C:\wamp\apps\phpmyadmin3.4.10.1\libraries (change path according to your installation)

open config.default.php and change value for $cfg['ExecTimeLimit'] to 0:

$cfg['ExecTimeLimit'] = 0;

This will resolve the issue for PhpMyAdmin imports.

This is the the right answer:

go to

c:\wamp\apps\phpmyadmin3.4.10.1\libraries\config.default.php

find and set

$cfg['ExecTimeLimit'] = 0;

restart all services and done.

WAMP USERS:

1) Go to C:\wamp\apps\phpmyadmin

2) Open config.inc

3) Add $cfg['ExecTimeLimit'] = ’3600′; to the file.

4) Save the file and restart the server.

This file overwrites the php.ini and will work for you!

Xampp Users

1. Go to xampp\phpMyAdmin\
2. Open config.inc.php
3. Search for $cfg['ExecTimeLimit'] = 300;
4. Set a larger value or change to 0 for unlimited
5. If not found add $cfg['ExecTimeLimit'] = 900; (or 0 for unlimited)
6. Save the file and restart the server

Important: setting the execution time limit to unlimited is not recommended.

In my case, when I faced that error in Phpmyadmin, I tried MySQL-Front and import my DB successfully.

Note: You can still use the provided solutions under this question to solve your problem in Phpmyadmin.

If above answers will not work, try to check your code,,In my experience,having an infinite loop will also cause that problem.Check your else if statement.

You can set time limit:

ini_set('max_execution_time', 1000000000000000);

In Codeignitor version 3.0.x the system/core/Codeigniter.php do not contain the time constraint as well as inserting

ini_set('MAX_EXECUTION_TIME', -1);

will not work since codeignitor will override that with its own function set_time_limit() . So either you have to delete that function from codeignitor or simply you can insert

set_time_limit('1000');

in the beginning of the php file if you wanna change that to 1000 seconds. Set the time to 0 (zero) if you want to run it as long as it want.

On Xampp, in php.ini you must check mysql.connect_timeout either. So, for example, change it to:

mysql.connect_timeout = 3600

That time will be always counted in seconds (so 1 hour in my example)

MAMP USERS editing php.ini solves this - there is a line:

max_execution_time = 30 ; Maximum execution time of each script, in seconds

setting this to a higher value worked.

the file is in php/php5.6.25/conf/php.ini (obviousl you need to wet the file for the php version you are using - you can find this out from the MAMP preferences.

go to the xampp/phpmyadmin/libraries/config.default.php

and make the following changes

from  $cfg['ExecTimeLimit'] = ’300′;
to  $cfg['ExecTimeLimit'] = ’0′;

For Local AppServ

Go to C:\AppServ\www\phpMyAdmin\libraries\config.default.php

Find $cfg['ExecTimeLimit'] and set value to 0.

So it'll look like

$cfg['ExecTimeLimit'] = 0;

For Xampp Users

1. Go to C:\xampp\phpMyAdmin\libraries
2. Open config.default.php
3. Search for $cfg['ExecTimeLimit'] = 300;
4. Change to the Value 300 to 0 or set a larger value
5. Save the file and restart the server
6. OR Set the ini_set('MAX_EXECUTION_TIME', '-1'); at the beginning of your script you can add.

If you are on xampp and using phpMyadmin to import large sql files and you have increased max_execution time, max file upload limit and everything needed And If none of the above answers work for you come here

Go to your xampp folder, in my case here is the relative path to the file that I need to modify: C:\xampp\phpMyAdmin\libraries\config.default.php

* maximum execution time in seconds (0 for no limit) * * @global integer $cfg['ExecTimeLimit'] * by defautlt 300 is the value * change it to 0 for unlimited * time is seconds * Line 709 for me */ $cfg['ExecTimeLimit'] = 0;

On wamp in my configuration where I have multiple phpmyadmins, the values in config files were overwritten in wamp/alias/phpmyadmin.conf. I set up two lines there:

1. php_admin_value max_execution_time 3600

2. php_admin_value max_input_time 3600

... it finally worked!

If xampp in localserver Goto C:\xampp\phpMyAdmin\libraries\config.default.php

//find $cfg['ExecTimeLimit']= 300;
//increase this value
$cfg['ExecTimeLimit'] = 3000;

For OpenServer

modules\system\html\openserver\phpmyadmin\libraries\config.default.php

change

$cfg[‘ExecTimeLimit’] = 600

So, after spending hours, this works for me (JUNE 2022)

1. adding $cfg['ExecTimeLimit'] = 6000; into xampp/phpMyAdmin/config.inc.php

2. also I change $cfg['ExecTimeLimit'] = 6000; in xampp/phpMyAdmin/libraries/configdefault.php
