新人问老问题:PHP的代码用什么来调试?
PHP代码用什么工具来调试?网上有说var_dump ,但我没明白是怎么用的,还有其他什么更简单的方法吗?
我是新手,回答时还请一定详细些。非常感谢。
------解决方案--------------------
1、看错误日志,也最直接的
2、脚本中间强制截取 var_dump();exit;
3、php debug
------解决方案--------------------
echo / print_r/ var_dump() 常用的就这几个。
然后再打开php的错误提示功能
------解决方案--------------------
一直用
echo '
';<br> print_r($var);<br> 怎么破?<br><font color="#FF8000">------解决方案--------------------</font><br>调试??不知道你用的开发工具是什么 初学者用记事本,将写出来的网页运行,若不是自己想要的结果,可以进行 echo 一下 最简单!并且一般情况下,sql语句会写错 ,那你echo 一下该sql 将结果放到数据库中运行,看看哪里有错 <div class="clear"> </div>
