Remove unknown characters

[The Little Guy]

I am building a xml file via php, and I am having a problem once in a while.

 

sometimes I get weird characters in the results, for example:

<title>Gimme What Ya Got (feat. Lil Wayne)�</title>

 

That little square before </title> is making the xml file fail.

 

the xml file error:

error on line 38 at column 45: Char 0x0 out of allowed range

 

So my question...

 

I can I remove all invalid characters before I insert them into my database?

well, lets see if this helps you out..

using eregi we can remove anything thats not a number or letter

 

here is an example of the code below: http://ju.nu/test/eregi.php

 

<?php

$string = "<title>Gimme What Ya Got (feat. Lil Wayne)?</title>";
$cleansedstring = ereg_replace("[^A-Za-z0-9]", "", $string );
echo $cleansedstring;

?>

 

hope this helps

I need all the characters though, I just don't want them to be formatted, where \0 = null I want \0 = \0

 

if that makes sense...

You shouldn't use ereg_replace as it's depreciated and removed as of PHP 6.0.0, instead use preg_replace().

its just so many years of the ereg_replace

 

i'll be sure to note.
