php的dl函数用法实例,dl函数实例
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:
http://www.php.net/manual/en/function.dl.php
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。
dl() is not supported in multithreaded Web servers.
貌似,是不支持多线程。。
1.需要加载php扩展
dl("php_w32api.dll");
2.从你的dll里面导出函数,假定该函数在dll里面被声明为FuncDll,并且返回值是int类型
w32api_register_function("函数所在的dll",
"FuncDll",
"int");
3.好了,现在你可以调用它了
$result = FuncDll();

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
