I have a table that acts as a dropbox for files that get automatically queued. I have a form that is automatically queued as a dropbox file. I order the priority of files based on two things, the date and time, and if it has been verified or not. I prioritize files based on two things, the date and time, and whether or not it was validated. Here is my query: This is my query: $dropcount = mysql_query(“SELECT COUNT(*) FROM queue WHERE status=2 OR status=3 OR status=4 ORDER BY authorized DESC, timestamp DESC;”); What I need to do is count how many rows are ahead of the users current file because this will count every row, including the files behind the current users as well. What I need to do is count how many lines are ahead of the user’s current file, as this will count every line, including files after the current user. Thank you. Thank you!

In PHP, the operator problem $a+$a++ and $a+$a+$a++ are both equal to 3?
$a = 1; why $a + $a++ and $a + $a + $a++ Are both equal to 3? picture: Response content: $a = 1; why $a + $a++ and $a + $a + $a++ Are both equal to 3? picture: Another problem with PHP operator precedence For details, please refer to: operator precedence First case: $a = 1; var_dump($a + $a++); At this time, $a++ is operated first; $a + $a++ is equivalent to: 2 + 1, so the result is 3; The second case: $a = 1; var_dump($a + $a + $a++); At this time, it is operated from left to right, $a + $a is operated first, and the result is: 2, and the result is saved. Then calculate $a++ (the previously calculated value of $a+$a=2 will not be affected), the above is equivalent to: 2 + 1 and the result is still 3 Finally, where do so many boring, cheating questions come from? The last PHP operator priority level is really a pain in the ass! ! !
In PHP, in a project with complex logic, how to check the complete execution process?
Requirements:Because the project is already relatively complicated, sometimes it is necessary to monitor the stacking and popping of specific functions, call, and the program calls the cache and db server. I need a program to monitor my code. Is there anything you can recommend? I checked a lot of information, trace, xdebug, xhprof, etc. I am dazzled and I don’t know which one can be used. Is there any useful open source class library, can you recommend it for expansion?
