I have a PHP web app running on a shared Ubuntu server that uploads images to Amazon S3 storage. On a mobile phone the camera can be used to upload a photo directly.
All worked fine until someone upgraded the version of PHP and the uploads stop working.
It turns out that this had reset the PHP file upload settings to their defaults, giving a max upload size of 2Mb which was too small for photos taken on the mobile phone.
The fix, with some help from ChatGTP , was to update the following php.ini file settings
; Maximum allowed size for uploaded files.
; http://php.net/upload-max-filesize
upload_max_filesize = 256M
; Maximum size of POST data (must be equal or larger than upload_max_filesize)
; http://php.net/post-max-size
post_max_size = 280M
; Max execution time for scripts (seconds)
; http://php.net/max-execution-time
max_execution_time = 90
; Optional: Max input time for parsing data (seconds)
max_input_time = 60
and also update the Apache config (i.e. /etc/apache2/sites-available/000-default.conf), setting LimitRequestBody in the <Directory> block to an appropriate size for the bytes allowed in the request body.
<Directory /var/www/xxx>
...
LimitRequestBody 268435456
</Directory>An apache restart got the uploads working again
sudo systemctl restart apache2Being on a shared server I also updated the .htaccess file just in case there was a later need for the server settings to be changed.
php_value upload_max_filesize 256M
php_value post_max_size 272M
php_value max_execution_time 90
php_value max_input_time 90
php_value memory_limit 384MThe settings in the .htaccess file override the php.ini settings when using Apache + mod_php.
