Question

I need to display mathematical function formulas.
For this, how can i echo those mathematical symbols using php?

Suppose i have a textbox on webpage, if someone types something there, then the special unicode characters like alpha, beta, summation or my local language characters will be typed there, can i do something with php to do this?

Answer 1

You can use html entity codes to show these symbols.
eg:

<div>
    &#931;
    &#945;
</div>

However, to show complex formulae,tis is not as easy as putting HTML entities to show mathematical symbols.
