MySQL 3.23.52
Configuration and Compilation
--prefix=/demo/mysql
MySQL's tree top
--with-unix-socket-
path=/demo/tmp/mysql.sock
Needed with multiple MySQL instances per box
--with-mysqld-user=praxis
MySQL will completely drop root and run as this
user
MySQL offers many other configuration
options:
DB handlers (InnoDB) provide transactions etc.
Compilation tweaks for improved performance
MySQL AB binaries are recommended for
production systems (notably on Linux)

Maintainable configuration for future PHP versions
Ensure proper httpd.conf directives:
LoadModule php4_module libexec/libphp4.so
Load PHP DSO
AddType application/x-httpd-php .php
Pass .php files to PHP
AddType application/x-httpd-php-source .phps
Pass .phps (source) files to PHP for syntax highlighting

Getting AMP Online
The data layer (MySQL) is already started
Fire up the interface layer:
/demo/apache/bin/apachectl start
http://demo.nyphp.org:8000/sql/
phpMyAdmin is a good test to ensure everything is
properly loaded and configured

Putting AMP to Work
initial.phps
http://demo.nyphp.org:8000/code/initial.phps
View source with PHP's built-in
highlighting
GET method checking as a failsafe
Override php.ini setting
Show errors in browser (stdout)
Get MySQL connection online
localhost connections use UNIX domain sockets
Create array of queries
PHP forms a sequential integer-indexed array

Putting AMP to Work...
initial.phps
Loop through queries, processing and error
checking
Reconnect to MySQL with the same DB
resource
Different username/password implies new
connection
Old resource is dereferenced and freed by garbage
collector
Create nested arrays for member
information
Automatic sequential integer-indexed array
Each element contains a user-defined associative
array
Loop through members, forming proper
query
INSERT will generate non-zero ID
(auto_increment)
