Dear Expert,

I get one simple php script test and program on my Linux shell command line
like myuser@mydomain/public_html/php myprogram.php ,          and I got the fatal error
out of memory (allocated 8388608)(tried to allocated 71 byte) in /home/mydomain/public_html/myprogram.php
But interesting that is  if I run it in IE browser, it works succesfully

Running it in IE,  it will echo memory usage=8,588,338 when $c<50,000, so i means it run succesfully at http://mydomain.com/myprogram.php
Runing it in IE ,it will echo memory usage=41,000,000 when $c<200,000, so it means it run sucessfully at http://mydomain.com/myprogram.php

Running it in Linux command line, it won't echo memory usage, and it stdout the
Fatal error:out of memory (allocated 8388608)(tried to allocated 71 byte) in /home/mydomain/public_html/myprogram.php
on line 4.
so it  won't run correctly.

If it can run  in IE for the same script, it means the probelm is not  issue at memory_limt setting in php system and the script shoud cost less than
41Meg when $c<50,000. And running it in IE , it is no issue for 41Meg memory when $c <200,000
I talked to my share-server company support, they replied and confirmed and I checked my php memory limit is 128Meg already
The issue they reply that might be PHP version is not set correctly in my script, myprogram.php if running it at command line shell.
 Do you agree that ?
How can I set correct PHP version in php script ?  I think that  issue is not related to memory_limit setting and PHP version
setting, it might relate to they might limit my php script running at command line, but no limit when run it in IE broswer

I go to check it in Cpanel for php configurate, memory_limt is 128Meg already and
I go to check it in phpinfo() in Linux php  script, it also report 128meg already and
I go to check ,htaccess file, php_value memory_limit 128M is also set already

So the issue is related to what ? memory allocation issue at command line or others ?

Please advise

myprogram.php==========================<?phpini_set('memory_limit', '128M');for ($c=0 ;$c<50000;++$c) {$linerow[$c]="aaaaaaaaaaaaaaaaaaaaaaaaaa";}echo "memory  usage=".memory_get_usage(). "";?>

Also, nothing in '.htaccess' is used when you run from the command line.  '.htaccess' is only used by Apache.

First, PHP Only runs on the server, not in the browser.  But second, in current distributions of Linux, Apache2 usually has one copy of 'php.ini' that is used when PHP is run thru the server and there is a second copy somewhere in one of the PHP directories that is used when you run PHP from the command line.  They do not have to be the same.  Tell us what version of Linux you are running.

memory_limit can not be changed via ini_set (See ini-definition in the php manual)
Form the command line try:

php -d memory_limit.php /home/mydomain/public_html/myprogram.php

php on the command line uses another php.ini as you webserver. compare phpinifo from command line with that from your webserver
