===PHP===
php is a web scripting language from the last generation. It's fast to write but hard to maintain. Anyone who has studied software engineering will find this "language" a nightmare.

===php5 typical source configure options (64bit redhat)===
In any case, you will need libtool-ltdl-devel to the least
%%
./configure --with-libdir=lib64 --libdir=/usr/lib64 --with-apxs2=/usr/local/apache2/bin/apxs \
--sysconfdir=/etc --with-config-file-path=/etc --with-config-file-scan-dir=/etc/php.d --with-bz2 \
--with-curl --with-freetype-dir=/usr --with-png-dir=/usr --with-gd=shared --enable-gd-native-ttf \
--without-gdbm --with-gettext --with-iconv --with-jpeg-dir=/usr \
--with-openssl --with-pspell --with-xmlrpc=shared --with-regex=php --with-zlib \
--with-layout=GNU --enable-bcmath --enable-exif --enable-ftp --enable-magic-quotes \
--enable-sockets --with-mysql=shared,/usr --with-mysqli --enable-shmop \
--enable-calendar --enable-mbstring=shared --enable-mbregex \
--enable-pcntl --enable-wddx --with-libxml-dir=/usr --with-mcrypt=/usr
%%
If you do not need so much crap, here is a minimal install
%%
./configure --with-config-file-path=/etc --with-config-file-scan-dir=/etc/php.d \
--prefix=/usr --with-mysql=shared,/usr --with-mysqli=shared,/usr/bin/mysql_config \
--enable-mbstring --with-apxs2=/usr/sbin/apxs
%%
=== Compiling PHP5 /w mysql5 & GD & Apache2 & Mysqli support ===
The following is tested on FreeBSD6.2.
//Note: There seems to be a problem compiling the following plus MagickWand. If MagickWand is compiled at the same time, it will stop at mysql_error.//
Install first from source
~zlib-1.2.3
~gd-2.0.43
~autoconf (ports)
~autoheader (ports)
~unixODBC (ports)
~"patch" php source with magickwand
~MySQL-5.0.37 binary in /usr/local/mysql
%%(bash)
./configure \
--host=i386-FreeBSD-6.2 \
--build=i386-FreeBSD-6.2 \
--target=i386-FreeBSD-6.2 \
--with-apxs2=/usr/local/sbin/apxs \
--with-mysql=/usr/local/mysql \
--with-zlib=/usr/local \
--enable-ftp \
--enable-versioning \
--with-gd=/usr/local \
--with-unixODBC=/usr/local \
--with-mysqli=/path_to/mysql_config
# seems not working --with-mysql=shared,/usr/local/mysql
# will not compile with --with-magickwand=/usr/local
%%
To test php & mysql, write a simple php page to fetch records. First, create a table on the test database:
%%(sql)
create table first_table(name varchar(20), id integer);
insert into first_table (name) values ('name1');
insert into first_table (name) values ('name2');
commit;
%%
Then retrieve these records from php:
%%(php;sqltest.php)
<?php
$link = mysql_connect('127.0.0.1','root','')
or die('Cannot connect:' . mysql_error());
echo 'Connected successfully.';
mysql_select_db('test') or die('Could not select database test');
// Perform sql query
$query = 'SELECT * from first_table';
$result = mysql_query($query) or die('Query failed:' . mysql_error());
// Print result in HTML
echo "<table>\n";
while ($line = mysql_fetch_array($result, MYSQL_ASSOC)) {
echo "\t<tr>\n";
foreach ($line as $col_value) {
echo "\t\t<td>$col_value</td>\n";
}
echo "</tr>\n";
}
echo "</table>\n";
// Free resultset
mysql_free_result($result);
//Closing connection
mysql_close($link);
?>
%%
=== Compiling PHP on system with pre-installed PHP ===
Obtain existing configure options by
%%(bash)
php -i | grep configure
# pipe configure command to a file
php -i | grep configure | sed s/#039//g | sed s/\&\;//g | cut -d\> -f5 | cut -d\< -f1 > phpconf
%%
Obtain php source code and use the same configure options to compile php
=== Compiling PHP with imap-2006 source===
This is one of those things...
1. Download imap source from http://www.washington.edu/imap/
2. Extract to /usr/local/imap-2006k
3. **make IP6=4 lrh**
4. mkdir /usr/local/imap-2006k/lib
5. mkdir /usr/local/imap-2006k/include
6. cp /usr/local/imap-2006k/c-client/*.h /usr/local/imap-2006k/include/
7. cp /usr/local/imap-2006k/c-client/*.c /usr/local/imap-2006k/lib/
8. cp /usr/local/imap-2006k/c-client/c-client.a /usr/local/imap-2006k/lib/libc-client.a
9. configure php with these options: **--with-imap=/usr/local/imap-2006k --with-imap-ssl=/usr/loca./imap-2006k**
=== Compiling PHP with ImageMagick and MagickWand support ===
Assuming php is already installed on RHEL4 in form of rpm and I want to add additional modules to php. BTW, RHEL is crap. Go for CentOS with yum if you absolutely need redhat compability.
The dependencies are horrible. I have no idea why php get so popular.
== Obtain the followings ==

>>
**x86_64 workaround**
The new way:
--with-libdir=lib64 --libdir=/usr/lib64
The old way:
# ln -s /usr/include /opt/include
# ln -s /usr/lib64 /opt/lib
set these in your ./configure and it should compile
--with-jpeg-dir=/opt --with-png-dir=/opt --with-mysql=/opt --with-imap=shared,/opt
# Then if you see an error with make, try
EXTRA_CFLAGS=-fPIC make
>>
== Install ImageMagick (make will take some time...) ==
%%(bash)
./configure
make && make install
# verify
/usr/local/bin/convert logo: logo.gif
%%
== Install MagickWand to php source ==
Extract MagickWand source to php's source under the ext folder. Rename MagickWand's folder to magickwand. Go in the magickwand directory and run the following.
%%(bash)
# phpize
Configuring for:
PHP Api Version: 20020918
Zend Module Api No: 20020429
Zend Extension Api No: 20021010
%%
In php source directory
%%(bash)
rm ./configure
./buildconf --force
%%
Compile php by appending the followings to the existing configure option. To obtain existing configure options, issue php -i | grep configure
%%
--with-magickwand=IMG_MGCK_DIR(/usr/local) --with-apxs2=/usr/sbin/apxs
make
%%
== Replace existing php binary and libphp4.so ==
backup /usr/bin/php and /etc/httpd/modules/libphp4.so
do a make install in php source
== Configure Apache ==
If apache is not configured previously, add the following line to make apache recognize php files:
%%
AddType application/x-httpd-php .php
%%
== Testing ==
Write a simple php page with phpinfo() inside. The resulting web page should contain a section of magickwand.
%%(php;phpinfo.php)
<?php
phpinfo();
phpinfo(INFO_MODULES);
?>
%%
==Sample php.ini to start with==
%%(text;php.ini)
[PHP]
extension_dir = "/usr/lib/20060613"
extension = mysql.so
extension = gd.so
extension = imap.so
%%
== MBString==
In addition, if MBString is necessary, it can be compiled in easily. Simply compile php **--with-mbstirng=all** and then add the followings to php.ini
%%
; Set default language
mbstring.language = Neutral; Set default language to Neutral(UTF-8) (default)
mbstring.language = English; Set default language to English
mbstring.language = Japanese; Set default language to Japanese
;; Set default internal encoding
;; Note: Make sure to use character encoding works with PHP
mbstring.internal_encoding = UTF-8 ; Set internal encoding to UTF-8
;; HTTP input encoding translation is enabled.
mbstring.encoding_translation = On
;; Set default HTTP input character encoding
;; Note: Script cannot change http_input setting.
mbstring.http_input = pass ; No conversion.
mbstring.http_input = auto ; Set HTTP input to auto
; "auto" is expanded to "ASCII,JIS,UTF-8,EUC-JP,SJIS"
mbstring.http_input = SJIS ; Set HTTP2 input to SJIS
mbstring.http_input = UTF-8,SJIS,EUC-JP ; Specify order
;; Set default HTTP output character encoding
mbstring.http_output = pass ; No conversion
mbstring.http_output = UTF-8 ; Set HTTP output encoding to UTF-8
;; Set default character encoding detection order
mbstring.detect_order = auto ; Set detect order to auto
mbstring.detect_order = ASCII,JIS,UTF-8,SJIS,EUC-JP ; Specify order
;; Set default substitute character
mbstring.substitute_character = 12307 ; Specify Unicode value
mbstring.substitute_character = none ; Do not print character
mbstring.substitute_character = long ; Long Example: U+3000,JIS+7E7E
