PHP coding standards for user entered data
<p>Recently we are facing lot of problems with user entered data</p>

<p>like</p>

<ol>
<li>They are using different languages</li>
<li>entering special characters like " ' </li>
</ol>

<p>How to deal with all these, after one problem..we are facing another.</p>

<p>OR, are there any coding standard or advanced tutorials available?</p>

<p>Thanks</p>
