 Posted: Mon Nov 17, 2003 2:20 pm Post subject: Safely testing PHP5 |
 |
|
Is is possible to test PHP5 together with PHP4? (Like with PHP 3 and 4 that only files with .php5 extentions will be parsed by php5?)
I have only a (production) server to test PHP5 on at this moment. I don't want to upgrade PHP4 now, but maybe I can run both versions?
Is the above possible? Or do I have to jump some other loops? (Please tell me which loops.  ) |

Edit: lol, I just realized that this is a really old thread. When I read it before I thought it said June 17 2004 for some reason. I probably should have written this reply in a newer thread, but oh well, it's too late now.
I was wondering the same thing. I configured Apache in a way that should theoretically execute all *.php5 files with PHP5 and the rest with PHP4 if you supply both -D PHP4 and -D PHP5. With that setup I could use either PHP4 or PHP5, but if I tried to use both all the PHP scripts would cause a segfault whether they were PHP4 or PHP5 files:
| Code: | [Wed Jun 16 17:44:56 2004] [notice] child pid 12121 exit signal Segmentation fault (11)
[Wed Jun 16 17:45:18 2004] [notice] child pid 12122 exit signal Segmentation fault (11)
[Wed Jun 16 17:45:24 2004] [notice] child pid 12123 exit signal Segmentation fault (11)
[Wed Jun 16 17:45:29 2004] [notice] child pid 12124 exit signal Segmentation fault (11) |
So I posted a question about this on #php and a guy there told me that PHP4 and PHP5 use the same memory space, so trying to run them at the same time is impossible (explains the segfaults). But that's okay, I can switch between -D PHP4 and -D PHP5 pretty easily, and PHP5 will still run PHP4 code just fine. Just download the PHP5 source code from http://www.php.net/downloads.php, extract it, cd, ./configure, make, and cp libs/libphp5.so to /usr/lib/apache2/extramodules, and add this to your /etc/apache2/conf/modules.d/70_mod_php.conf:
| Code: | <IfDefine PHP5>
<IfDefine !PHP4>
<IfModule !mod_php5.c>
LoadModule php5_module extramodules/libphp5.so
</IfModule>
<IfModule mod_mime.c>
AddType application/x-httpd-php .php
AddType application/x-httpd-php .phtml
AddType application/x-httpd-php .php3
AddType application/x-httpd-php .php4
AddType application/x-httpd-php-source .phps
AddType application/x-httpd-php .php5
</IfModule>
<Files *.php>
LimitRequestBody 524288
RequestHeader unset If-Modified-Since
</Files>
<Files *.php3>
LimitRequestBody 524288
RequestHeader unset If-Modified-Since
</Files>
<Files *.php4>
LimitRequestBody 524288
RequestHeader unset If-Modified-Since
</Files>
<Files *.php5>
LimitRequestBody 524288
RequestHeader unset If-Modified-Since
</Files>
<Files *.phps>
LimitRequestBody 524288
RequestHeader unset If-Modified-Since
</Files>
<Files *.phtml>
LimitRequestBody 524288
RequestHeader unset If-Modified-Since
</Files>
</IfDefine>
</IfDefine> |
Then in /etc/conf.d/apache2, make sure you have either '-D PHP4' or '-D PHP5' but not both. |

A very good (though no ultimately easy  ) way to solve this problem (and run PHP4 AND 5 together) is running a front-end proxy that forwards to a PHP4 or a PHP5 backend. The differentiation can easily be made on file extension, but other rules can also be used. This if ofcourse also for mixing different server-software (mix Apache 2 with apache1/zeus or a port of a webserver on a FreeBSD box)
(We use front-end proxies anyway, so it's not really a problem, but I can imagine its too much trouble to go through, though.)
