I have a some text saved in a MySql database that contains a mathematical symbol. When I read this from php code it become something like this α=?
and β=?
Text in database:
<p>A round balloon of radius r subtends an angle α at the eye of the observer, while the angle of elevation of the centre is β. The height of the centre of balloon is </p>
Text read from php:
<p>A round balloon of radius r subtends an angle ? at the eye of the observer, while the angle of elevation of the centre is ?. The height of the centre of balloon is </p>
How to solve this problem?
