1、PHP自己的框架实现错误显示和记录日志
2、运行时错误set_error_handler和致命错误register_shutdown_function KJ.php
public static function run(){
//定义常量
self::_set_const();
//创建模块目录
self::_mk_module();
//加载文件
self::_import_file();
self::_set_system();
set_error_handler(array(__CLASS__,'error'));//运行时错误
register_shutdown_function(array(__CLASS__,'fatal_error'));//致命错误
//类自动加载
spl_autoload_register(array(__CLASS__,'_autoload'));
//运行框架
self::_run();
}3、错误信息处理KJ.php
public static function fatal_error(){
if ($e = error_get_last()) {;
self::error($e['type'],$e['message'],$e['file'],$e['line']);
}
}
public static function error($errno, $error, $file, $line){
$err_code="";
switch ($errno) {
case E_ERROR:
case E_PARSE:
case E_CORE_ERROR:
case E_COMPILE_ERROR:
case E_USER_ERROR:
$msg=$error.$file."第{$line}行";
errHalt($msg);exit;
case E_STRICT:
case E_USER_WARNING:
case E_USER_NOTICE:
default:
if(config('DEBUG')){
$msg=$error.$file."第{$line}行";
errLog($msg);
include KJ_CORE.'/tpl/notice.tpl';exit;
}
}
}
4、记录处理日志方法function.php
function errHalt($error,$level='ERROR',$type=3,$dest=NULL){
if(is_array($error)){
errLog($error['message'],$level,$type,$dest);
}else{
errLog($error,$level,$type,$dest);
}
$e=array();
;
if(config('DEBUG')){
if(!is_array($error)){
$trace=debug_backtrace();
$e['message']=$error;
$e['file']=$trace[0]['file'];
$e['line']=$trace[0]['line'];
$e['class']=isset($trace[0]['class'])?$trace[0]['class']:"未知";
$e['function']=isset($trace[0]['function'])?$trace[0]['function']:"未知";
ob_start();
debug_print_backtrace();
$e['trace']=htmlspecialchars(ob_get_clean());
}else{
$e=$error;
}
}else{
$e['message']='系统错误';
}
include KJ_CORE.'/tpl/halt.tpl';
die();
}
function errLog($msg,$level="ERROR",$type=3,$dest=NULL){
if(is_null($dest)){
$dest=CACHE.'/errLog/'.date("Ymd").".log";
}
if(!is_dir(CACHE.'/errLog')){
mkdir(CACHE.'/errLog', 777);
}
error_log("time:".date("Y-m-d H:i:s").
"{$level}:{$msg}\r\n",$type,$dest);
}5、错误显示模板
1、halt.tpl

6、错误演示indexCrl.php
1、运行时错误
<?php
class indexCrl extends CrlBase {
public function index(){
$add;
var_dump($add);exit;
}
}2、致命错误
<?php
class indexCrl extends CrlBase {
public function index(){
$add
var_dump($add);exit;
}
}
