Below is a partial list of configure options used by the PHP configure scripts when compiling in Unix-like environments. Most configure options are listed in their appropriate locations on the extension reference pages and not here. For a complete up-to-date list of configure options, run ./configure --help in your PHP source directory after running autoconf (see also the Installation chapter). You may also be interested in reading the GNU configure documentation for information on additional configure options such as --prefix=PREFIX.
Note: These are only used at compile time. If you want to alter PHP's runtime configuration, please see the chapter on Runtime Configuration.
Note: These options are only used in PHP 4 as of PHP 4.1.0. Some are available in older versions of PHP 4, some even in PHP 3, some only in PHP 4.1.0. If you want to compile an older version, some options will probably not be available.

--with-phttpd=DIRNo information yet.
--with-pi3web=DIRBuild PHP as a module for use with Pi3Web.

--enable-roxen-ztsBuild the Roxen module using Zend Thread Safety.
--with-servlet[=DIR]Include servlet support. DIR is the base install directory for the JSDK. This SAPI requires the java extension must be built as a shared dl.

--with-webjames=SRCDIRBuild PHP as a WebJames module (RISC OS only)
--disable-cgiDisable building CGI version of PHP. Available with PHP 4.3.0.
--enable-force-cgi-redirectEnable the security check for internal server redirects. You should use this if you are running the CGI version with Apache.
