====== php information ======

The command  php --ini  returns this result:

<code>
Configuration File (php.ini) Path: /etc
Loaded Configuration File:         /etc/php.ini

Scan for additional .ini files in: /etc/php.d

Additional .ini files parsed:      /etc/php.d/dbase.ini,
/etc/php.d/json.ini,
/etc/php.d/mysql.ini,
/etc/php.d/mysqli.ini,
/etc/php.d/pdo.ini,
/etc/php.d/pdo_mysql.ini,
/etc/php.d/pdo_sqlite.ini,
/etc/php.d/zip.ini
</code>

====== configure PHP ======

This is a very special instruction for configuring our own special edition of PHP.  The steps are configure, make, make install.

Upload tar to: /usr/local/src

tar xjvf tarball.tar.bz2

cd to the new folder created by untarring the tarball.

====== APC PHP cache ======
[[http://www.howtoforge.com/apc-php5-apache2-fedora8]]

Next time I have to remake PHP:

  * configuration option "php_ini" is not set to php.ini location
  * add "extension=apc.so" to php.ini?

Specifying the location of the module helped:
<code>
;MXM Add APC cache
extension=/opt/php5/include/php/ext/apc/apc.so
apc.enabled=1
apc.shm_size = 48
</code>

====== Exclude PHP & sendmail from yum update ======

[[http://www.cyberciti.biz/faq/redhat-centos-linux-yum-update-exclude-packages/]]

Added:

''exclude=php* sendmail*''

in /etc/yum.conf

If I let yum update PHP, it changes my active php.ini file AND it does not include all of the bells and whistles that phpMyAdmin needs.

sendmail updates are [[http://qmail.jms1.net/fake-smtp.shtml|liable to break the link to qmail's sendmail function]].
