maximum size of uploads in php depend on number of settings. here they are, as put into apache virtual hosts file:
php_admin_flag file_uploads on php_admin_value memory_limit 560M php_admin_value post_max_size 530M php_admin_value upload_max_filesize 500M php_admin_value max_execution_time 0 php_admin_value max_input_time 0
please ignore the values above, but they enable me to allow uploads of around 150-200M. memory_limit, post_max_size and upload_max_filesize have some specific ratios between each other. i believe that
upload_max_filesize < post_max_size < memory_limit
however, i dont' know how to calculate exact sizes. for example what must be values of these settings in order to allow exactly 100M file upload? from what i gathered online, there is number of factors that determine these ratios, but i couldn't find any references what are these factors.
i'm using linux system.
