Html-when a large amount of data is submitted using textarea, the $ _ POST array cannot be read in the php background.

The first is a page form with only one input and textarea. When the input data in textarea is relatively small (for example, section 1000), I can use the php $ _ POST array to read data in the background, however, if the input data in textarea is large (such as 0.1 million bytes), I use php in the background... the first is a page form with only one input and textarea. When the input data in textarea is relatively small (for example, section 1000), I can use the php $ _ POST array to read data in the background, however, if the input data in textarea is large (for example, 0.1 million bytes), the $ _ POST array in php can only read the content in the input, but the content in textarea cannot be read.

Then I checked on the internet, saying that the server (I used the javaser integrated environment) configuration problem, need to modify php. in ini, The post_max_size parameter is changed to 20 mb and is passed through phpinfo. php printing check has indeed changed, but still cannot be obtained.

Hope Daniel can help, TKS.

Modify three parameters in php:
Upload_max_filesize
Post_max_size
Memory_limit

Modify one nginx parameter:
Client_max_body_size 35 m; # Set the size of the uploaded file on the client to 35 M.

This is not just a change here. It seems that the maximum upload value of Apache/Nginx needs to be changed.
