Memory_limit, as you can probably guess by
its name is the command that limits the
memory usage of PHP within WordPress.
The memory_limit value that you set must be
greater than the file that you are trying upload.
This is the amount of memory required to
upload files or run commands. The
recommended limit is 128 MB.
3. max_execution_time
This command defines the time it takes to
execute each script. This command tells the
server how long it takes to execute the
commands.
It will take longer if you upload large files to
the server. You can either increase or reduce
the execution time.
4. post_max_size
This command sets the maximum data that a
post can contain. This value can be changed
to zero to remove the restriction. You can call
the server post using the POST method.
5. upload_max_filesize
This command sets the maximum file that you
can upload to WordPress. You've probably
seen the WordPress gallery limit on the
number of files you can upload. This command
defines the limit.
You must either remove or increase the
memory limit exhaust error if it occurred.
6. maximum_input_time
This command specifies the time it takes to
analyze each data. Data such as POST and
GET.

The time ends when the command begins.
The default value for this parameter is 1. This
limitation can be eliminated by setting the
value to 0.

The default value is E_ALL & ~E_NOTICE, all
errors except notices. Development servers
should be set to at least the default; only
production servers should even consider a
lesser value
