How to quickly carry out PHP debugging, I believe that many inexperienced people do not know what to do, so this paper summarizes the causes of the problem and solutions, through this article I hope you can solve this problem.

PHP debugging

In the development machine environment, you can only use VIM and Emacs (I use Emacs). There are no comparative tools for debugging PHP. Here is a function I often use:

File_put_contents ('/ tmp/my.log', print_r (array (date ('Y-m-d Hlav iarray'), _ _ LINE__, _ _ METHOD__,), TRUE)

This function can output a log to the / tmp/my.log file, including the date on which the function was executed, on which line, and by which method. After _ _ METHOD__, you can add the variable we want to print, such as $a, and then look like this:

File_put_contents ('/ tmp/my.log', print_r (array (date ('Y-m-d Hlav iarray'), _ _ LINE__, _ METHOD__, $a), TRUE), FILE_APPEND | LOCK_EX)

Then we rerun the code and open a new window to monitor the log changes:

$tailf / tmp/my.log

So we can print out the $a variable.

After reading the above, have you mastered how to debug PHP quickly? If you want to learn more skills or want to know more about it, you are welcome to follow the industry information channel, thank you for reading!
