WEB 5 PLAN ,
WEB 6 PLAN .
At Alden Hosting we eat and breathe Java! We are the industry leader in providing
affordable, quality and efficient Java web hosting in the shared hosting marketplace.
All our sites run on our Java hosing platform configured for
optimum performance using Java 1.6, Tomcat 6.0.X, MySQL 5.0.x, Apache 2.2.xx and web
application frameworks such as Struts, Hibernate, Cocoon, Ant, etc.
We offer only one type of Java hosting - Private Tomcat. Hosting accounts on the Private
Tomcat environment get their very own Tomcat server. You can start and re-start
your entire Tomcat server yourself.
Loads the PHP extension given by the parameter
library.
Use extension_loaded() to test whether a given
extension is already available or not. This works on both built-in
extensions and dynamically loaded ones (either through php.ini or
dl()).
Parameters
library
This parameter is only the filename of the
extension to load which also depends on your platform. For example,
the sockets extension (if compiled
as a shared module, not the default!) would be called
sockets.so on Unix platforms whereas it is called
php_sockets.dll on the Windows platform.
The directory where the extension is loaded from depends on your
platform:
Windows - If not explicitly set in the php.ini, the extension is
loaded from c:\php4\extensions\ by default.
Unix - If not explicitly set in the php.ini, the default extension
directory depends on
whether PHP has been built with --enable-debug
or not
whether PHP has been built with (experimental) ZTS (Zend Thread Safety)
support or not
the current internal ZEND_MODULE_API_NO (Zend
internal module API number, which is basically the date on which a
major module API change happened, e.g. 20010901)
Taking into account the above, the directory then defaults to
<install-dir>/lib/php/extensions/ <debug-or-not>-<zts-or-not>-ZEND_MODULE_API_NO,
e.g.
/usr/local/php/lib/php/extensions/debug-non-zts-20010901
or
/usr/local/php/lib/php/extensions/no-debug-zts-20010901.
Return Values
Returns TRUE on success or FALSE on failure. If the functionality of loading modules is not available
(see Note) or has been disabled (either by turning it off
enable_dl or by enabling safe mode
in php.ini) an E_ERROR is emitted
and execution is stopped. If dl() fails because the
specified library couldn't be loaded, in addition to FALSE an
E_WARNING message is emitted.
Examples
Example 1. dl() examples
<?php // Example loading an extension based on OS if (!extension_loaded('sqlite')) { if (strtoupper(substr(PHP_OS, 0, 3)) === 'WIN') { dl('php_sqlite.dll'); } else { dl('sqlite.so'); } }
// Or, the PHP_SHLIB_SUFFIX constant is available as of PHP 4.3.0 if (!extension_loaded('sqlite')) { $prefix = (PHP_SHLIB_SUFFIX === 'dll') ? 'php_' : ''; dl($prefix . 'sqlite.' . PHP_SHLIB_SUFFIX); } ?>
Notes
Note: dl() is not supported in
multithreaded Web servers. Use the extensions
statement in your php.ini when operating under such
an environment. However, the CGI and
CLI build are not
affected !
Note:
As of PHP 5, the dl() function is deprecated in every
SAPI except CLI.
Use Extension Loading Directives
method instead.
Note:
Since PHP 6 this function is disabled in all SAPIs, except CLI, CGI and
embed.
