ob_end_clean 出错了,求教!

Jun 23, 2016 pm 02:05 PM

我想用set_error_handler来统一收集错误,在打印自定义错误提示前,我用了ob_end_clean();但是报错了

PS:我开启了gzip

测试代码:

error_reporting(E_ALL);set_error_handler(array('test', 'handle_error'));if(function_exists('ob_gzhandler')) {    ob_start('ob_gzhandler');} else {    ob_start();}class test {        public static function handle_error($errno, $errstr, $errfile, $errline) {        if($errno) {             debug::system_error($errstr);        }    }}class debug {        public static function system_error($message) {        ob_end_clean();                echo $message;                exit;    }}echo '错误前信息<br/>';trigger_error('错误内容');
Copy after login


上述代码测试,就报错了。。。ob_end_clean()注释掉就没关系。。。

我对ob_start理解不深,求赐教!

顺便贴一下错误:
chrome浏览器下
错误 330 (net::ERR_CONTENT_DECODING_FAILED):未知错误

error_reporting(E_ALL);set_error_handler(array('test', 'handle_error'));if(function_exists('ob_gzhandler')) {    ob_start('my_ob_gzhandler');} else {    ob_start();}class test {    public static function handle_error($errno, $errstr, $errfile, $errline) {        if($errno) {            debug::system_error($errstr);        }    }}class debug {    public static function system_error($message) {        ob_clean();        echo $message;        exit;    }}echo '错误前信息<br/>';trigger_error('ddddddddddddddddddddddddd误内容');function my_ob_gzhandler($buffer,$mod){    header("Content-Encoding: gzip");    return gzencode($buffer, 9, FORCE_GZIP);}
Copy after login

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

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,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
