私家调试函数求优化
私人调试函数求优化
1.可能有点异想天开,我希望获取调用这个函数的文件的文件名和行数,目前的死办法是外面传__FILE__和__LINE__
2.我想获取外面传的调试变量的名称,例如你有个变量叫 $abc = 'fdsafs'; 这样赋值了,然后 debug($abc); 我能在这个函数内部想办法知道这个变量的名称叫 abc
3.获取变量类型,类似别的语言的typeof,现在来一个变量,假设它是字符串,却没办法echo typeof($data) ,却要if(is_string($data))echo 'string';...
4.你能提出的更多优化建议,写一写你的改造结果~
====================
这个函数从当初最简单的
function debug($data, $die = false){
echo '
';<br> print_r($data);<br> echo '
if($die)die();
}
到今天如下面的代码,已经是一年多了~方便自己调试变量值.我也懒得学那些什么复杂的调试框架什么xDebug..其实我要调试的需求在上面说的和下面代码体现的都有了,没更多的要求.
大家有没有试过,在一个很大的程序体里,到处echo一些值,在调试完后修正代码后,运行时还发现有调试的echo值输出,却不记得这个echo放哪里了- - 所以我需要知道这个调用的文件位置和行号.包括其它更多的调试需求,其实也不是很多,知道变量内容,长度,类型,它变成这个内容的文件位置就行了.
上代码:
$a = 'xx';
$b = 45;
$c = true;
$d = false;
$e = null;
$f = new stdClass();
$g = array(
'a' => 'v1',
'b' => 'v2',
);
debug($a);
debug($b);
debug($c);
debug($d);
debug($d);
debug($e);
debug($f);
debug($g);
function debug($data, $die = false, $file = null, $line = null){
static $debugCount = 0; //调试计数器
echo '
================= 新的调试点: '.++$debugCount.'========================
';
if($file)echo "文件名: $file
\n";
if($line)echo "行数: $line
\n";
$len = strlen($data);
if($len)echo '内容长度:'.$len."
\n";
echo "变量名称: a
\n"; //有没有办法获取到外面传参时,debug($a);的变量名称 'a'?
echo "
\n";<br> print_r(var_export($data, true));<br> echo "
if($die){
exit('
返回');
}
else return $debugCount;
}
------解决方案--------------------
function debug()<br />{<br /> global $config;<br /> if(!$config['debug']) {<br /> return;<br /> }<br /><br /> echo '<pre class="brush:php;toolbar:false">';<br /> foreach(func_get_args() as $var)<br /> var_dump($var);<br /> echo '
}
function fdebug()
{
global $config;
if(!$config['debug']) {
return;
}
foreach(func_get_args() as $var) {
file_put_contents('./aaa_yii_debug.php', ''.PHP_EOL . PHP_EOL, FILE_APPEND);
