Solution to php not displaying error messages: First open the "etc/php.ini" file in the php directory; then add the content as "error_reporting(E_ALL);ini_set('display_errors','On') ;";Finally save the file.
Recommended: "PHP Video Tutorial"
On some servers, when the PHP code execution error occurs, browse The programmer will only display 500 errors, which is not conducive for programmers to locate error codes.
There are 2 settings for turning on PHP error message display:
1: error_reporting = error reporting level (if it is development mode, please set it to: E_ALL)
2: display_errors = On
These two settings are indispensable. When display_errors=Off, no error information will be displayed no matter what level error_reporting is set to.
Setting method:
1: Modify the etc/php.ini file in the php directory
2: Add to the php code:
error_reporting(E_ALL); ini_set(‘display_errors’,’On’);
Attached error_reporting error level code:
值 常量 描述 1 E_ERROR 致命的运行错误。错误无法恢复,暂停执行脚本。 2 E_WARNING 运行时警告(非致命性错误)。非致命的运行错误,脚本执行不会停止。 4 E_PARSE 编译时解析错误。解析错误只由分析器产生。 8 E_NOTICE 运行时提醒(这些经常是你代码中的bug引起的,也可能是有意的行为造成的。) 16 E_CORE_ERROR PHP启动时初始化过程中的致命错误。 32 E_CORE_WARNING PHP启动时初始化过程中的警告(非致命性错)。 64 E_COMPILE_ERROR 编译时致命性错。这就像由Zend脚本引擎生成了一个E_ERROR。 128 E_COMPILE_WARNING 编译时警告(非致命性错)。这就像由Zend脚本引擎生成了一个E_WARNING警告。 256 E_USER_ERROR 用户自定义的错误消息。这就像由使用PHP函数trigger_error(程序员设置E_ERROR) 512 E_USER_WARNING 用户自定义的警告消息。这就像由使用PHP函数trigger_error(程序员设定的一个E_WARNING警告) 1024 E_USER_NOTICE 用户自定义的提醒消息。这就像一个由使用PHP函数trigger_error(程序员一个E_NOTICE集) 2048 E_STRICT 编码标准化警告。允许PHP建议如何修改代码以确保最佳的互操作性向前兼容性。 4096 E_RECOVERABLE_ERROR 开捕致命错误。这就像一个E_ERROR,但可以通过用户定义的处理捕获(又见set_error_handler()) 8191 E_ALL 所有的错误和警告(不包括 E_STRICT) (E_STRICT will be part of E_ALL as of PHP 6.0)
