I have run a query direct in phpmyadmin only 5 sec time taken but when load in php query than i face this error Query execution was interrupted
max_statement_time exceeded
i check the phpmyadmin and have a wrapper inside Util.php ...function .....#set_time_limit((int) $GLOBALS['cfg']['ExecTimeLimit']); ... and lead to config.values.php 'ExecTimeLimit' => 'validateNonNegativeNumber', or just in case to config.inc.php ( could be like this https://stackoverflow.com/a/13858161/5781320 ) : in my case isn't a value set you may check if in your case is!
if you do not find anything you should check php.ini "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 " -> https://www.php.net/manual/ro/function.set-time-limit.php

The weirdest thing happened today. When I run this query:
DELETE FROM some_table WHERE id IN(5)
I get a 30 second timeout error in PHP. The same query runs without issues on my local development server, but when I move it to the production server, I get the timeout.
No sqlite error or anything like that, just "Fatal error: Maximum execution time of 30 seconds exceeded " :|
What could be the problem? Is there any way I could debug this at least?
In top of all my new codes I put this function
ini_set('max_execution_time',60);
reference .
to debug my script execute time I use this
$start = microtime(true);
function execute(){global $start;$end = microtime(true);$time=number_format(($end - $start), 5);return$time;}
//..... your code here
echo '<br><b>.'Page Loaded In 'execute().' Seconds<b/>';
I am facing this problem, firstly I would like to say that I am very new to PHP and MySQL.
Fatal error: Maximum execution time of 30 seconds exceeded in
.........................\cdn\wished.php on line 3
I don't know what is wrong in line 3, its giving error only sometimes. Here's my code:
<?php
//wished.php
$CheckQuery = mysql_query("SELECT * FROM users WHERE ownerid='$user->id'");
$wished = 0;
while($row = mysql_fetch_assoc($CheckQuery))
{
// echo $row['fname']."<br/>";
$wished++;
}
echo $wished;
?>
It was perfect when I run this in localhost with XAMPP. As soon as I hosted my app on my domain and used their database, it start getting error.
thanks every one :)
The issue is that the SQL query is taking too long, and your production PHP configuration has the PHP script time limit set too low.
At the beginning of the script you can add more time to the PHP time limit:
http://php.net/manual/en/function.set-time-limit.php
set_time_limit(60);
for example to add 30 more seconds (or use 0 to let the PHP script continue running).
If your production database is different than your development DB (and I'm assuming production has way more data) then it might be a really expensive call to get everything from the user table.
I use joomla connect to postgresql:
$db = JFactory::getDBO();
$db->setQuery($query);
$db->query();
$object = $db->loadAssocList();
Default timeout=30s. I want set timeout =120.
How set timeout of query? Thanks.
set_time_limit
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.
When called, set_time_limit() restarts the timeout counter from zero. In other words, if the timeout is the default 30 seconds, and 25 seconds into script execution a call such as set_time_limit(20) is made, the script will run for a total of 45 seconds before timing out.
you need to use the standard php function
set_time_limit(120);
Is it possible to get Max Execution timeout notification so that i can use code clean up operations before the php script stops running?
Basically, i am trying to create a script that can do some changes/modifications to my database which has huge data pile. Also, this php script execution can be paused/resumed using a filelock.
You can either use set_error_handler() or register_shutdown_function().
Edit: See also: max execution time error handling
If you set 0 to set_time_limit, it will never stop :)
You can increase the limit time inside your code using:
set_time_limit(300); //time in seconds
ini_set('max_execution_time', 300); //300 seconds = 5 minutes
or
changing the max_execution_time parameter inside your php.ini.
The default time is 30 seconds.
I have a weird problem with mysqli timeout options, here you go:
I am using mysqli_init() and real_connect() in order to set MYSQLI_OPT_CONNECT_TIMEOUT
$this->__mysqli = mysqli_init();
if(!$this->__mysqli->options(MYSQLI_OPT_CONNECT_TIMEOUT,1))
throw new Exception('Timeout settings failed')
$this->__mysqli->real_connect(host,user,pass,db);
....
Then I am initiating query on locked table (LOCKE TABLE users WRITE) and its just hanging, ignoring all my settings even:
set_time_limit(1);
ini_set('max_execution_time',1);
ini_set('default_socket_timeout',1);
ini_set('mysql.connect_timeout',1);
I understand why set_time_limit(1) and max_execution_time is ignored but why other timeouts and especially MYSQLI_OPT_CONNECT_TIMEOUT are ignored and how to solve it.
I am using PHP 5.3.1 on Windows and Linux boxes, please help.
MYSQLI_OPT_CONNECT_TIMEOUT seems to configure the timeout at connect-time :
connection timeout in seconds
(supported on Windows with TCP/IP
since PHP 5.3.1)
Here, you are trying to execute a query on a locked table... Which means you have a query that takes a lot of time (like forever) ; but you are already connected to the database.
So, what should be configured is not the connection timeout ; but some "query timeout".
Not sure how to set that "query timeout", though...
Maybe the MYSQLI_CLIENT_INTERACTIVE flag for mysql_real_connect could help, in a way or another ?
There's innodb_lock_wait_timeout. But as the name suggests it's only for InnoDB tables.
The timeout in seconds an InnoDB transaction may wait for a row lock before giving up. The default value is 50 seconds. A transaction that tries to access a row that is locked by another InnoDB transaction will hang for at most this many seconds before issuing the following error:
ERROR 1205 (HY000): Lock wait timeout exceeded; try restarting transaction
In addition to Pascal MARTIN's answer:
PHP is sleeping until the query completes - so anything you've configured for PHP is ignored. If the query ever does return, then PHP will wake up and continue processing - at which point it will realise it has run out execution time and end abruptly - will it release the locks it has acquired? Maybe.
One solution would be to implement your own locking schema, e.g.
$qry="UPDATE mydb.mylocks SET user='$pid' WHERE tablename='$table_to_lock' AND user IS NULL";
$basetime=time();
$nottimedout=5;
do {
mysql_query($qry);
$locked=mysql_affected_rows();
if (!$locked && $nottimedout--) sleep(1);
} while (!$locked && $nottimedout);
if ($nottimedout) {
// do stuff here
}
mysql_qry("UPDATE mydb.mylocks SET user=NULL WHERE tablename='$table_to_lock' AND user='$pid'";
I guess a neater solution would be to implement this as a trigger on the table - but my MySQL PL/SQL is a bit ropey.
