"[" and "]" character on CDATA

[Joel Pablo]

hi,

im doing a shoutbox on flash and php .. everything is cool but when the user input has "[" or "]" character in it... the xml structure freaks out because of these character inside the CDATA tag.E:

<xmlElement>
   <![CDATA[
   <br> Hey paw! you are cool! [kewl]    ]]>
</xmlElement>


.. see the kewl word was inside the bracket, and that were my problem occur .. iwant to avoid that  error.

FYI im using php to write to the xml file ... and then output the xml values in flash .. is there a way php cud overide this

thanks in advanced!

You can replace the [] with another characters or simply by empty spaces using ereg_replace, (that use regexps) I.e

$text = ereg_replace"\[*(\]|\[)", " ", $xmlstring)

In this example, you replace any "[]" in $xmlstring with an empty space

To replace special HTML characters you can use the htmlspecialchars() function, that take a string and return a string with the doble quote, "&", "<" and ">" replaced with the correspond HTML entity
