Dealing with special charters inputed 3

[pugs421]

When my friend enters his screen name &quot;D<O>A&quot; it is outputted on the results page as &quot;DA&quot;. What is the way around this problem?

in straight HTML you woul do...
D>O<A

in PHP you can use the htmlspecialchars() function to do this for you.

Would the new code be put in when the information is displayed, or when it is entered

That is nearly impossible to say. How are you going to use that value?

Hi,

You could do this too:

$var = &quot;D<O>A&quot;;

$search = array (&quot;'<'&quot;, &quot;'>'&quot;
$replace = array (&quot;&amp;lt;&quot;, &quot;&amp;gt;&quot;

$result = preg_replace ($search, $replace, $var);

Hope this helps!

spyderix is absolutely right that one should use the HTML entities that correspond to the symbols that are reserved HTML characters.
It is easy to get a list of HTML entities.

I'd still say it's easier to use htmlspecialchars() and let the PHP guys maintain the list of reserved HTML characters for you, and worry about all the optimizations and whatnot.


(And sorry about my first post, it told me in preview that & l t ; was properly encoded to show up but then turned it into a less than anyway.)

skiflyer,

There seems to be a problem with Tek-Tips regarding that. The preview shows it correctly but then when you submit from the preview it screws up.

To properly show that on here you have to type &amp;amp;lt;

&quot;Unknown has caused an unknown error in unknown, unknown will now unknown.&quot;
