[RESOVLED - OR CLOSE ENOUGH]Recompile PHP

[roopurt18]

I am needing to recompile PHP on my webhost, which happens to be Server Powered.  They can do it for me, but I'd rather not have to always bother them to enable a new option when compiling the PHP binary.  I have root access to my account so I can do this myself; however I only know enough about the linux OS to be dangerous but not efficient.

After logging in, I change to dir / and issue the commands:
[code]
> find . -name "*php*.tar*"
./usr/local/cpanel/src/3rdparty/gpl/phpPgAdmin-4.0.1.tar.gz
./usr/local/cpanel/src/3rdparty/other/php-4.4.2.tar.gz
./usr/local/src/php-4.4.4.tar.gz

> cd /usr/local/src
> ls -l

From this I'm gathering that if I need to edit install_php.sh to enable or disable my PHP installation.  If i then run install_php.sh, I assume it changes me into the php-4.4.4 directory and runs the configure program.

From then, what do I need to do to compile and install PHP?  There already is apache (1.3 I believe) and PHP set up and running.  I'd like to just recompile PHP and stick it in the same place where it currently resides.  Can I keep my old php.ini or will a new one be created?  The webhost installed a PEAR module for me, will that still be available?

I have a pretty good sense of what I'm doing up until the actual point of compiling PHP, replacing the old one, and making sure I don't lose any of the old settings.

If it helps, inside my httpd.conf for the Apache server is the following:
[code]
LoadModule php4_module        libexec/libphp4.so
AddModule mod_php4.c
[/code]

Thanks for any help!

I just did a search for libphp4.so and came up with:
[code]/usr/local/apache/libexec/libphp4.so
/usr/local/src/php-4.4.4/.libs/libphp4.so
/usr/local/src/php-4.4.4/libs/libphp4.so[/code]

Am I right to assume that when I do recompile PHP it will create a new libphp4.so in the /usr/local/src/php-4.4.4 area that I will need to copy over to /usr/local/apache/libexec ?

[roopurt18]

Ok, so I'm able to compile and install a new libphp4.so.  For thoroughness and anyone else in this situation in the future, here's what I did.

From /usr/local/src:
[code]
> bash install_php.sh
> cd php-4.4.4
> make
> cp /usr/local/src/php-4.4.4/libs/libphp4.so /usr/local/apache/libexec/libphp4.so
> /usr/sbin/apachectl restart
[/code]

Now loading a phpinfo() page displays the new command line options I specified.  However, it doesn't solve the original problem I had set out to solve.

One of my scripts was using memory_get_usage() which is disabled if PHP is not built with the --enable-memory-limit option.  I suppose this particular installation doesn't allow that flag to be set, so I'll have to use a workaround function.

I'll probably just adapt this code, posted by [i]e dot a dot schultz at gmail dot com[/i] at http://php.net/memory_get_usage:
[code]
<?php
if( !function_exists('memory_get_usage') )
{
  function memory_get_usage()
  {
      //If its Windows
      //Tested on Win XP Pro SP2. Should work on Win 2003 Server too
      //Doesn't work for 2000
      //If you need it to work for 2000 look at http://us2.php.net/manual/en/function.memory-get-usage.php#54642
      if ( substr(PHP_OS,0,3) == 'WIN')
      {
              if ( substr( PHP_OS, 0, 3 ) == 'WIN' ):
              $output = array();
              exec( 'tasklist /FI "PID eq ' . getmypid() . '" /FO LIST', $output );
     
              return preg_replace( '/[\D]/', '', $output[5] ) * 1024;           
      }else
      {
          //We now assume the OS is UNIX
          //Tested on Mac OS X 10.4.6 and Linux Red Hat Enterprise 4
          //This should work on most UNIX systems
          $pid = getmypid();
          exec("ps -eo%mem,rss,pid | grep $pid", $output);
          $output = explode("  ", $output[0]);
          //rss is given in 1024 byte units
          return $output[1] * 1024;
      }
  }
}
?>
