in [General]
|
From: "fyang" on 20 Jul 2010 20:34 Dear all, I have a simple test code in different OS ,but it give me a different result. the code as follows: <?php $n= 50000; for($i=0;$i<$n;$i++) { $data[]=array("",$i,$i/1000); echo $i," ",$data[$i][1],"<br>"; } echo "count:",count($data); ?> OS1: Red Hat Enterprise Linux Server release 5.1 Linux 2.6.18-53.el5xen i686 i686 i386 GNU/Linux test result: the result is correct,it can display 50000 data and count:50000. OS2: CentOS release 5.4 Linux 2.6.18-164.el5 x86_64 x86_64 x86_64 GNU/Linux test result: the result is wrong,it can only display 31148 data and it can not display count value. I'm not sure the result relate to array capacity in different OS. Please give me some tips,thanks in advance. good luck, Yang Fei 2010-7-20

Did you really have to post the same message eight times? CentOS is Red Hat minus the proprietary elements, so you actually have two releases of the same OS here. The bigger question is what version of PHP are you running on each of them and how are they configured? Bob McConnell
From: "fyang" on 21 Jul 2010 22:34 Dear Bob McConnell, Thank you for your reply. I really post the same message eight times because of the first e-mail authentication.please remove the extra e-mail in your free time. There are two servers ,the first installation of 32-bit linux(RHEL),the second installlation 64-bit linux(CENTOS). PHP version on 32-bit linux(RHEL):5.2.7 PHP version on 64-bit linux(CENTOS):5.2.13 I found this problem,because the software transplantation.In the 64-bit systems,the array seems to always have limited capacity. I'm not sure that is php version problem or need other configurations. Please give further guidance, thank you very much! best wishs, Yang Fei 2010-7-22 ·¢¼þÈË£º Bob McConnell ·¢ËÍʱ¼ä£º 2010-07-21 20:06:36 ÊÕ¼þÈË£º fyang; php-general(a)lists.php.net ³ËÍ£º Ö÷Ì⣺ RE: [PHP] php array in different OS From: fyang > I have a simple test code in different OS ,but it give me a different > result. > the code as follows: > <?php > $n= 50000; > for($i=0;$i <$n;$i++) > { > $data[]=array("",$i,$i/1000); > echo $i," ",$data[$i][1]," <br >"; > } > echo "count:",count($data); > ? > > OS1: Red Hat Enterprise Linux Server release 5.1 > Linux 2.6.18-53.el5xen i686 i686 i386 GNU/Linux > test result: the result is correct,it can display 50000 data and > count:50000. > > OS2: CentOS release 5.4 > Linux 2.6.18-164.el5 x86_64 x86_64 x86_64 GNU/Linux > test result: the result is wrong,it can only display 31148 data and it > can not display count value. > I'm not sure the result relate to array capacity in different OS. > Please give me some tips,thanks in advance.

I'm not sure that is php version problem or need other configurations. I suspect it's just different configuration. That said, I've generally found that 64bit versions of PHP need more memory than their 32bit equivs, so perhaps all you need to do is something like: ini_set('memory_limit', '50M'); and you'll be fine.
