Find the php. ini file in/etc/php5/apache2/and modify the following:
1. max_execution_time
The default value is 30 seconds. if it is set to 0, there is no limit. this parameter is mainly used to set the longest execution time of the php page. for example, the default value is 30 seconds, indicating that the script will stop execution if the execution is not completed 30 seconds later.
Of course, if special processing is required in special cases, call the method on the page:
Set_time_limit (max_time );
2. post_max_size
In php, this parameter is set to 2 M by default. if the size of POST data is greater than post_max_size, $ _ POST and $ _ FILES superglobals will be blank. this parameter also affects file upload.
3. upload_max_filesize
Many people have changed the parameters 1 and 2, but the maximum size of the file to be uploaded is still 8 M. because the default value of upload_max_filesize is 8 M, we should modify the value of this parameter.
In addition, post_max_size is better than upload_max_filesize.
