PHP Warning之max_input_vars

The following is the error message

PHP Warning: Unknown: Input variables exceeded 4000. To increase the limit change max_input_vars in php.ini. in Unknown on line 0

A php background management system in the company, which was previously running on apache. Later, after I switched to nginx+php, other functions ran normally. There was a modification function that failed to submit the form after submitting the form. I checked the code and found no problem. Then I looked at the PHP error log and found no clues. Print After the post request, I also found that the number of submitted forms and the number of forms being processed did not match (at that time, I wondered whether a certain plug-in was not installed and whether the character sets were correct). I looked at the logs of php-fpm again and found that it was a bit confusing. The information is available for reference.

To increase the limit change max_input_vars in php.ini. in Unknown on line 0" , it is recommended to modify max_input_vars in the php.ini file. PHP has added a variable max_input_vars starting from 5.3.9 to limit the number of submitted forms. Damn, my function (similar to the phpmysqladmin function, which reads the database table and then writes and edits it, and there are 128 database fields, and then each field has 11 input boxes) has about 1,400 inputs, ( What a painful realization, why am I so worried about developing a table with so many fields),

Reading logs is very important The above introduces the max_input_vars of PHP Warning, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
