这篇文章主要介绍了php的dl函数用法,以实例形式讲述了利用dl函数突破PHP设置上的限制,是非常实用的技巧,需要的朋友可以参考下

本文实例讲述了php的dl函数用法。分享给大家供大家参考。具体如下:


PHP的dl函数官网说明如下:

具体用法示例如下:

复制代码 代码如下:

// 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

复制代码 代码如下:

extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/"
;extension=memcache.so

希望本文所述对大家的PHP程序设计有所帮助。
