For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.

<h1>File upload in PHP - test script</h1>
This is a complete file upload demonstration in PHP, and it
is intended that you install a copy on your own server to
test uploads. <b>Please note that this demonstration
quarantines the uploaded file in a directory that's well away
from the document root, and only gives you minimal access to
look at the file - giving you timestamp and size data only.
These limits are applied to prevent the scripot being used as
a backdoor to introduce unwanted content to the web site that
you are testing.</b><hr>

<form enctype=multipart/form-data method=post>
<input type=hidden name=MAX_FILE_SIZE value=250000>

Many visitors to our web site come here because they have
found our <a href=xxx>PHP image upload - store in database
- retreive - display demonstration script</a>.  Although
that script is short, it uses a lot of elements one after
another and from "popping a picture in" at one
end to "pulling it out" at the other, a lot happens behind
the scenes.   This sample page / script if you look at the
source shows you how to test the first stage.<br><br>
The second test stage is to save the image into the database,
pull it back, and make sure it is still the same<br><br>
And the final test stage is to send it back as an http response.
