Instalação e Configuração
On my Debian system I wrestled with something similar after apt-get ting updates for PHP and MYSQL, turns out the apt-get install worked great but broke my libphp module under apache. Once this module was deleted, I was able to rebuild it under PHP using ./configure
All works well now.

O arquivo de configuração
O arquivo de configuração (php.ini) é lido quando o PHP inicia. Para as versões de módulo de servidor, isso acontece apenas quando o servidor web for inicializado. Para as versões CGI e CLI, isso acontece à cada invocação.
php.ini é procurado nesses lugares (na ordem):
-
Local específico do módulo SAPI (diretiva PHPIniDir no Apache 2, -c opção de linha de comando quando CGI e CLI, parâmetro php_ini no NSAPI, variável de ambiente PHP_INI_PATH no THTTPD)
-
A variável de ambiênte PHPRC. Antes do PHP 5.2.0 isto era conferido depois da chave de registro mencionada abaixo.
-
A partir do PHP 5.2.0, os seguintes locais do registro são procurados em ordem: HKEY_LOCAL_MACHINE\SOFTWARE\PHP\x.y.z\IniFilePath, HKEY_LOCAL_MACHINE\SOFTWARE\PHP\x.y\IniFilePath and HKEY_LOCAL_MACHINE\SOFTWARE\PHP\x\IniFilePath, where x, y e z significam as versôes do PHP maior, menor e release.
-
HKEY_LOCAL_MACHINE\SOFTWARE\PHP\IniFilePath (Local no registro do Windows)
-
Diretório de trabalho atual (exceto CLI)
-
O diretório do servidor web (para módulo SAPI), ou diretório do PHP (caso contrário, no Windows)
-
Diretório do Windows (C:\windows ou C:\winnt) (para o Windows), ou ou a opção de tempo de compilação --with-config-file-path
Se php-SAPI.ini existe (onde SAPI é o SAPI usado, então o nome de arquivo é, por exemplo, php-cli.ini ou php-apache.ini), é usado ao invés do arquivo php.ini. nome SAPI pode ser determinado pela função php_sapi_name().
Nota: O servidor web Apache muda o diretório para raiz durante a inicialização, causando com que o PHP tente ler o arquivo php.ini da raiz do arquivo de sistema, se ele existir.
As diretivas do arquivo php.ini tratadas por extensões são documentadas respectivamente nas páginas das próprias extensões. A lista de diretivas principais está disponível no apêdice. No entanto, provavelmente nem todas as diretivas do PHP estão documentadas no manual. Para uma lista completa das diretivas disponíveis na sua versão do PHP, por favor leia seu arquivo php.ini. Também há alternativa de baixar a » última versão do arquivo php.ini dos repositórios do CVS, que pode ser de ajuda também.
Exemplo #1 php.ini example
; any text on a line after an unquoted semicolon (;) is ignored
[php] ; section markers (text within square brackets) are also ignored
; Boolean values can be set to either:
; true, on, yes
; or false, off, no, none
register_globals = off
track_errors = yes
; you can enclose strings in double-quotes
include_path = ".:/usr/local/lib/php"
; backslashes are treated the same as any other character
include_path = ".;c:\php\lib"
A partir do PHP 5.1.0, é possível acessar as variáveis .ini dentro dos arquivos .ini. Exemplo:open_basedir = ${open_basedir} ":/new/dir".

Hello,
Having tried EVERYTHING on every php / mysql site to get php5.2.5 to talk to mysql server 5.0 (including all php.ini settings, all dlls, and many more ...)
Please try this: set Apache2.2 service Startup Type to MANUAL. If not, it does not see to reload php.ini, no matter how many times you stop and start.
After 2 days, I finally see mysql info for <?php phpinfo(); ?>
Hope this helps!!

Be sure to use double quotes in the php.ini file. For instance:
(lines broken for readability)
this will work:
# xdebug debugging
zend_extension="/usr/local/php5/lib/php/extensions
/no-debug-non-zts-20060613/xdebug.so"
this won't:
# xdebug debugging
zend_extension='/usr/local/php5/lib/php/extensions
/no-debug-non-zts-20060613/xdebug.so'
You'll get this error:
Failed loading '/usr/local/php5/lib/php/extensions/
no-debug-non-zts-20060613/xdebug.so': (null)
So... double quotes are the way! I know this is obvious, but it's a good thing to remember for the php.ini file.

About Apache 2.0 module:
For whatever reason, the Windows installer for PHP/5.2.3 tries to set the PHPIniDir directive using "\\" as directory separator:
PHPIniDir "C:\\Archivos de programa\\PHP\\"
It didn't work for me until I edited httpd.conf and replaced it with "/":
PHPIniDir "C:/Archivos de programa/PHP/"

In order to get PHP 5.2 stable running on Windows Server 2003 x64 (IIS 6.0), I discovered three things (in addition to the other comments above):
* Some PHP web applications make use of the SCRIPT_NAME server variable which is not available under CGI. You have to use php5isapi.dll, which is a 32 bit dll, so you have to run IIS in 32 bit mode. Confer http://support.microsoft.com/kb/894435. This applies to all ISAPI extensions and not just ASP.NET.
* It appears you must leave the doc_root entry in php.ini blank. At least, that is what finally made my installation work. (Note that others have suggested to set it to e.g. C:\inetpub\wwwroot or equivalent. That won't work if your server hosts more than one domain, each placed in a separate directory.)
* If you are e.g. using MySQL you will have to edit php.ini. In order for it to be found, you must set the PHPRC system environment variable or the registry entry. Note that if you edit the registry using regedit.exe, the PHP key should be placed under the [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node] key. This happens automatically if you set it using a 32 bit legacy application.

Run php 4 and php 5.2.x on the same machine with IIS 6.0 as ISAPI.
1. Extract the ZIP packages of both php 4 & php 5 (not the Windows Installer) to c:\php4 & c:\php5 respectively
2. Setup the corresponding php.ini files in c:\php4 and c:\php5
3. Add the Web Service Extensions for php4 and php5. For php4 use c:\php4\sapi\php4isapi.dll, php5 use c:\php5\php5isapi.dll
4. Add the following registry keys:
HKEY_LOCAL_MACHINE\SOFTWARE\PHP\5\IniFilePath -> c:\php5
HKEY_LOCAL_MACHINE\SOFTWARE\PHP\IniFilePath -> c:\php4
5. Add c:\php4 to the PATH environment variable.
6. Associate each web site in IIS with the corresponding php version.
7. Reboot
Note: That should work, test with phpinfo() in each site. You may need to refer to the php documentation if we missed any other settings.

[ When php run as Apache Module ]
DOCUMENT_ROOT .htaccess
+======================================+
SetEnv PHPRC /home/user/dir-containing-phpinifile
+======================================+
[ When php run as CGI ]
Place your php.ini file in the dir of your cgi'd php binary, in this case /cgi-bin/
DOCUMENT_ROOT .htaccess
+======================================+
AddHandler php-cgi .php .htm
Action php-cgi /cgi-bin/php5.cgi
+======================================+
[ PHP run as cgi with wrapper (for FastCGI) ]
Your wrapper script should look something like:
+======================================+
#!/bin/sh
export PHP_FCGI_CHILDREN=3
exec /user/htdocs/cgi-bin/php.cgi -c /home/user/php.ini
+======================================+

Setting php.ini location for PHP working as Apache module (without use SetEnv directive in httpd.conf):
Before start Apache, set the PHPRC environment variable to the path where php.ini should be loaded, for example:
PHPRC=/etc/php4/apache-another-path
export PHPRC
In Debian we can do this way:
In /etc/init.d/apache (the script that loads apache web server) we have this line:
ENV="env -i LANG=C PATH=/bin:/usr/bin:/usr/local/bin"
Set to this:
ENV="env -i LANG=C PATH=/bin:/usr/bin:/usr/local/bin PHPRC=/etc/php4/apache-another-path"
Then wen you reload apache the php.ini will be loaded in the directory configured in PHPRC environment variable.

You can use also use the predefined PHP_SAPI constant instead of php_sapi_name().

For those people who want to use the PHPRC environment variable:
You have to specify the path to the directory containing your php.ini, not the direct path to the php.ini.
Example (php.ini resides in /your/path/php.ini):
right:
export PHPRC=/your/path
wrong:
export PHPRC=/your/path/php.ini

Please note that the SetEnv PHPRC "directory/to/phpini/" only works when using PHP as CGI, but _not_ when you use the PHP Apache Module!

For IIS users: If you experience high parsetimes, try to set output_buffering to On. IIS has problems with scripts outputting many small pieces of text, and with output_buffering = On, PHP sends the whole page to IIS in one piece.
