php fatal error out of memory
PHP Fatal error Out of memory
I am calling the below two function inside a function called RebuildSummary()
1. create_summary function
create_summary function fetches activity data from database and loop through activities using for each loop, and insert data into the below text file like below:
zfilename71801404123.txt
2. insertdatafromfile function
insertdatafromfile function will read the contents of the same text file[zfilename71801404123.txt] and insert them into the summary table using the command LOAD DATA.
System Configuration:
PHPINFO
My Question:
I am getting the below error while calling the RebuildSummary function.
I have enough memory on server side, still how the system display this error «Out of memory»

= 1.4G so you’re hitting a barrier around there
The first thing you should look at is you’re setting memory_limit: 20000M which is 20G. You’ve only 6G on your system. PHP may be confused and defaulting to a lower limit or there may be a hard limit for your version of php running on windows 7.
OR you could be running 32 bit Apache/PHP processes, which have hard limits around 2G see this: Upper memory limit for PHP/Apache
if you’re going through a tonne of data, do not use fetch_all() which is what I’m assuming you are using within your database class.
you should fetch each record individually, e.g.:
here is a simple benchmark someone did before to illustrate the difference in memory usage: https://stackoverflow.com/a/2771563/520857
spoiler: 100Mb vs 400bytes
Doesn’t matter how much ram you allow for PHP. If it’s a 32bit-compile, it could never use more than 4gig utter max, and practical

выделено 182 мб. этого ведь более чем достаточно?
подскажите, кто прав? я в том, что утверждаю, что ошибку (судя по логу) вызывают все скрипты не зависимо от требуемого объема памяти (от 1 до 8 мб при выделенных 128. ), к тому же, не совсем понятно, как нормально работающий и оптимизированный сайт без внесения каких-либо изменений в его код вдруг стал создавать ошибки? потом снова работает нормально? складывается впечатление, что с нагрузкой не справляется именно сервер?
или прав хостер, утверждая, что скрипты сайта работаю не нормально и потребляют слишком много памяти?
растолкуйте, я в ступоре. что делать?

PHP Fatal error: Out of memory (allocated 476053504) on Windows running php through cygwin #3983

I use phan from within cygwin and it was working fine in my setup, but apparently the ‘intl’ plugin was missing to enable correct verification of its usage.
Whatever I try, the program always fails at about 454MB. I did the following:
Line 156 corresponds to the following piece of code:
which is an ast operation.
Apparently there is a different memory limit for ast than there is for php because changing the memory limit has no effect even when setting a lower value.
I tried to find a memory option for AST to no avail.
The text was updated successfully, but these errors were encountered:

I’d recommend installing php from https://windows.php.net/ and using that instead of php installed through cygwin. Whatever php build emulating a build for linux isn’t supported by php’s maintainers and may have more edge cases like this.
If you wanted to enable it, it’s bundled with php’s zip in php_intl.dll
How much total memory does your computer have (in resource monitor)? How much of it is in use before running Phan?
[How to] Fix – PHP Fatal Error: Out Of Memory
Last night when I was moderating some comments on TechPP, I was shocked to see an error page instead of the admin panel dashboard. The error read something like this –
PHP Fatal error: Out of memory (allocated 49545216) (tried to allocate 77824 bytes) in /home/xxxxx/public_html/xyz/admin.php(1758) on line 40
The first thing I could think of was to restart the Apache httpd service. This immediately solved the issue. but I knew this is not a permanent fix for the issue. When I researched further, I got to know that the error comes when certain PHP scripts require more memory than PHP was allowed by default.
So the solution is to increase the memory allocated for PHP. How to do that? There are 4 possible ways –
1. Try looking for the php.ini file. You might find some redundant php.ini files, so make sure you have got the one which is actually being read by PHP. o be sure, create a new php file in your root folder, say “check.php” and have phpInfo(); within the php open and close tags. Execute this file to get the information on where the php.ini is residing. Normally it will be in /usr/local/lib/php.ini
Open the php.ini file in a text editor like TextPad (not in Notepad) and change the values for memory_limit. By default you should see memory_limit = 8M. Try changing it to 12M. If it doesn’t work, increase it to 16M or even 24M and so on.
2. In case you can’t find the php.ini file or do not have access to it, then open up the file which was throwing the error (admin.php in my case) and add a line below just after ini_set(’memory_limit’, ‘12M’);
3. You can even consider adding a line in .htaccess file which will resolve the issue.
php_value memory_limit 32M
4. Or else, Try adding this line to your wp-config.php file:
Increasing memory allocated to PHP
define(‘WP_MEMORY_LIMIT’, ’32M’);
If none of the above things solve your issue, then talk to you host. If you have a host like Knownhost who is fast and knows what needs to be done, you do not have to worry much.
Note: I am now worrying on which PHP script required an increase in memory allocation. The analysis won’t be so easy though.
I got this error when running composer.phar update on my VM:
PHP Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 144115188075867549 bytes) in phar:///bin/composer.phar/src/Composer/Util/RemoteFilesystem.php on line 179
The VM just recently recovered from a bad disk sector problem, and the guy running the VM said that the VM has been moved to a new disk. There are only Java, PHP, httpd, postgre, rabbitmq and the website itself in my VM, and it already ran perfectly for about 4 months before this happened. I’m using PHP 5.6.11. Can anyone help please?

Check the Composer’s troubleshooting wiki, especially the memory limit errors section.
For instance, by running the composer like this:
I get no error anymore. So it is probably an insufficient memory issue that can be solved inline, without altering your default PHP configuration.
Please note that instead of `which composer` you should probably use the real path of your composer.phar PHP script. The which composer written inline (like in my example above) will be inline solved to your composer.phar full path (you may use whatever form you like).
Note: in case both the physical and virtual memory is exceeded the above solution might fail as well. If that is the case then the obvious solution would be to increase your system’s virtual memory then try again.
The only thing that solve my problem was doing this:
From my experience, memory errors from composer usually means it is spending too much memory looking for the right combinations of packages to install, especially the version constraints are not specific enough. For example, ^5.2.4 matches 5.3 to 5.3.29, 5.4 to 5.4.45, etc. For each specific version and permutation, composer has to get the package’s dependencies to check if all the constraints are met. This is usually when the memory consumption gets huge.
