php的dl函数

http://www.php.net/manual/en/function.dl.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);

}

?>

dl("memcache.so");

这样只要php.ini中配置好就可以不要再引用so文件不然会说多处引用

extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/"

;extension=memcache.so
