Topic:
PHP Scripting Language;;Linux
System already set memory_limit=128M in php.ini and .htaccess
and we conclude the setting in php.ini and .htacess for Aapache only and not work for command line
we could not find out where the other php.ini is for command line and start a test to solve the issue as follow
and myprogram.php script requires only 42Meg to complete
Testing:
================
Test-1
php -f myprogram.php
Fatal Error: out of memory (allocated 8,388,608)(tried to allocated 71 byte) in /home/mydomain/public_html/myprogram.php
Test-2
php -n -d memory_limt=128Meg -f myprogram.php / /where -n "No php.ini file can be used"
Fatal Error: out of memory (allocated 27,262,000)(tried to allocated 71 byte) in /home/mydomain/public_html/myprogrm.php
Test-3
php -n d memory_limited=1Meg -f myprogram.php //for tesitng 1Meg setting
Fatal Error: Allowed memory size of 1Meg is exahusted
You can see only Test-3 is related to memory limit issue if you read the error message in which you can find the word of "exhausted"
In test-1 and test-2, they might not be related to memory_limit, it might be caused by other setting in ulimit -a command setting
Please advise why even we use -n option but we can NOT allocated more than 27.3Meg memory with memory_limit=128M set at command line ?

can use it on SSH but memory control by host , I can run it on IE
or by Lynx
Anyway, thanks a lot

Ah that's strange, because in the end doesn't the cron-job run from the shell too and also under the same user as you use on the ssh shell?
Also this is just my personal workstation, so it's not a hosted environment.

Is it your server VPS or share-server ? Which host company are you using ?
I want to collect your ulimit -a output to report to my host company for comparsion

Actually it's in kilobytes, so yes 32K.

my max locked memory is limited to 32M, that is 32K ? or 32M?

Ah sucks, sorry to hear about that, was hoping we could actually fix this.

Yep, seems like the same situation as yours. Can they raise the cpanel shell limitation?
Author: duncanb7 replied at 2024-05-21 04:14:48
Thanks for your reply and at
least finally get the answer even
it can not be solved.
Host says they don't change ulimit
setting for me for security reason

500 points EXCELLENT
Yeah what he says seems about right, because if you look at your ulimit output it says your max locked memory is limited to 32M.
My ulimit shows everything's unlimited:
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
file size (blocks, -f) unlimited
max locked memory (kbytes, -l) unlimited
max memory size (kbytes, -m) unlimited

stack size (kbytes, -s) 8192
cpu time (seconds, -t) unlimited
max user processes (-u) 266

Finally get the reply from host provider .
Hello Duncan,
It seems that the reason of the error occurs is not because of the PHP memory_limit usage of your script, but it is because the shell limitation. With cPanel shell, the problem could caused by the forkbomb setting of your cPanel limited the PHP memory.
Should you need more information, please don't hesitate to contact us.
Many Thanks,

They said it is 128Meg for php memory_limit and user can change any option in /usr/local/lib/php.ini
and also run it in my IE /FF broswer, it works and report out the memory usage=42M too in browsers.
But I don't know why it doesn't work at commnad line

Ah okay, if I run that I get:
Bender:~ ruben$ php -f test.php
memory usage=39526568
So approximately 39 mb.
I'm thinking that your hostingprovider capped the memory_limit. Possibly at 32mb. I think you should contact them to ask if it could be raised.

"If it works, why I go to switch to use

I don't know what you mean by that. I just said that ini_get('memory_limit') works just fine from cli too. It's not restricted to a web environment.

option -n, -c
-n "No php.ini file can be used"

php -f test.php
256Mmemory usage=10353720
And if I execute it without specifically setting the memory_limit:
<?phpecho ini_get('memory_limit');for ($c=0 ;$c<50000;++$c) {$linerow[$c]="aaaaaaaaaaaaaaaaaaaaaaaaaa";}echo "memory usage=".memory_get_usage(). ""; 1:2:3:4:5:6:7:
I get this:
php -f test.php
128Mmemory usage=10352968
So it never exceeds 10 mb of memory usage.
It seems like your settings are capped somewhere. Are you on a shared hosting environment?
Author: duncanb7 replied at 2024-05-21 02:37:31
it seems it is related to memory_limit because when I set
memory_limit, it report 8.3M allocated and if set memory_limit=1M
it report Allowed memory of 1M is exhausted. SO you can memory_limit
is reacting but can not let php allocate more memory than 42.M(my script requirement) or 128M
Is there for loop issue in my php script , too long of $c variable for ($c=0 ;$c<50000;++$c) {}
The pointer is too long to cause system error

ini_get('memory_limit') works from cli too, no problem.
Can you try it, cause I'm curious about the output.
Also make sure the user has read rights on the php.ini you're trying to use.

I try to copy system php.ini into my public_html directory and
try
php -c ./php.ini -f myprogram.php that get the same fatal error message
if editing and change memory_limit to 128M in my php.in at public_html , same error as test_1
if memory_limit=1M,same error as test-3
So it seems it realted to other setting for memory resource , How can use ulimit -a and set setting ?

init_get("memory_limit") is no use for command line, it won't read it,
That init_get() is for Apache only or running in IE/FF broswer only

Have you tried using the -c commandline switch to point specifically to the php.ini you want to use?
