A listing of available PHP configuration options

Question

Having browsed the net for a while, I've found that searching for a list of all the params available to add in the ./configure directive set when you make (compile) PHP is very hard to find since it will get you a lot of answers on how to use ini_set() and how to manipulate the php.ini file.

What I'm after - and it's probably available on the php.net site (which btw is one of the hardest sites to wrap your head around, navigation wise) - is a list / overview of what params are available and what they mean / do.

Just to avoid ambiguity, the params I mean are the ones used in a "configure" statement like so: (in PHP source folder) ./configure --enable-fpm --with-mysql --with-mysqli --with-gd etc etc etc.

Thanks.

I haven't compiled PHP in awhile, but I thought there was either a -h argument or a README provided with the PHP source that listed and explained the available arguments for configure.

Edit:
This should get you a complete list of the available arguments

./configure --help

Answer 2

Any configure script will print out its options when called with the --help parameter:

panther-g php-5.2.11 # ./configure --help

`configure' configures this package to adapt to many kinds of systems.

Usage: ./configure [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...),
specify them as VAR=VALUE. See below for descriptions of
some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
-h, --help              display this help and exit
--help=short            display options specific to this package ...  
--enable-sysvsem        Enable System V semaphore support  
--enable-sysvshm        Enable the System V shared memory support  
 --disable-tokenizer    Disable tokenizer support  
--enable-wddx           Enable WDDX support
--disable-xml           Disable XML support  
--disable-xmlreader     Disable XMLReader support  
--disable-xmlwriter     Disable XMLWriter support
...
--with-qdbm=DIR         DBA: QDBM support
--with-gdbm=DIR         DBA: GDBM support
--with-ndbm=DIR         DBA: NDBM support
--with-db4=DIR          DBA: Berkeley DB4 support  
--with-db3=DIR          DBA: Berkeley DB3 support
--with-db2=DIR          DBA: Berkeley DB2 support  
--with-db1=DIR          DBA: Berkeley DB1 support/emulation  
--with-dbm=DIR          DBA: DBM support
...

If you need specific extensions (like gd, for example), just look at the extension's documentation.
