[Php-debug] using php-l debug PHP error encountered pit

Sometimes, because of the increase in system code, causing many files to be interrelated, or some third interface (etc.), you have to debug online.

On-line environment, we are all set "Ini_set (' display_errors ', false)" in order to prevent errors from being exposed online, to avoid increasing the risk of code exposure, and to see a more user-friendly experience.

So, I developed a habit of directly on the Linux server, using Php-l to check the running files, and always thought that the command will also check the "Call undefined function" errors and so on.

It was only today that php-l only checked the simple syntax specification and did not check for other errors, such as: variable undefined, whether the called function exists, and so on.

In other words, php-l just checks the file's syntax and does not check the file for errors at all.

// # php-l application/controller/openplatform.php//no syntax errors detected in application/controller/ openplatform.php//called a nonexistent function--urlecode (), the error php-l is not checked out $weixin _register_url = "https:// Open.weixin.qq.com/connect/oauth2/authorize?appid=wxa5a632d87776f994&redirect_uri= ". Urlecode ($weixin _ Redirect_uri). ' =&response_type=code&scope=snsapi_userinfo&state=1#wechat_redirect ';
