Sharing of PHP debugging functions and logging functions, debugging logging

The development process of website programs often requires debugging, and operation logs also need to be recorded during the release phase to facilitate the discovery of problems and recovery of events. This requires debugging and logging capabilities.

The functions used for debugging and the functions used for recording errors are written below.

The method of use is very simple, and the log file is automatically generated based on the date:

Copy code The code is as follows:

//When debugging, multiple parameters are available:
sysdebug("hello");
sysdebug("hello", "tiger is coming now");

//The same is true for error records:
syserror("error");
syserror("error", "unfortunately tiger is dead ", "we are sad");

php debugging and logging functions, as follows:

Copy code The code is as follows:

/**
* Record debugging information
​*/
function sysdebug($msg) {
if (defined("DEBUG_MODE")) {
//TODO detects debugging switch and does not print when publishing
$params = func_get_args();
$traces = debug_backtrace();
$trace = array_pop($traces);
sysrecord($params, $trace, 'debug');
}
}

/**
* Record error message
​*/
function syserror($msg) {
$params = func_get_args();
$traces = debug_backtrace();
$trace = array_pop($traces);
sysrecord($params, $trace, 'error');
}

/**
* Write file
* @ignore
​*/
function sysfile($filename, $msg, $mode = null) {
$path = dirname($filename);
if (!file_exists($path)) {
mkdir($path, 0666, true);
}
$flag = LOCK_EX;
if ($mode) {
switch ($mode) {
case "add":
$flag = FILE_APPEND | LOCK_EX;
Break;
case "a":
$flag = FILE_APPEND | LOCK_EX;
Break;
         default:                                                                        break;
}  
}
file_put_contents($filename, $msg, $flag);
}

/**
* Record information
* @ignore
​*/
function sysrecord($params, $trace, $level) {
$path = dirname(__FILE__) . "/logs/";
//TODO log saving directory is best modified
 
$file = $trace['file'];
$func = $trace['function'];
if ($func == "sys$level") {
$func = '';
}
$filename = $path . "$level/" . date("Y-m-d") . '.log';
$msg = "[" . date("m-d H:i:s") . "] File:"" . basename($file) . "" Func:"" . $func . "" Msg:" . json_encode( $params) . "rn";
sysfile($filename, $msg, 'add');
}
