php的dl函數使用基礎教程

<?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");

這樣只要php.ini中配置好就可以不要再引用so文件不然會說多處引用

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

;extension=memcache.so
