RE: [PHP] Unwanted Characters

use eregi_replace("[asutk]+", '', $string)

in this way there will be no such letters as a,s,u,t,k in $string

How do I remove unwanted/unprintable characters from a variable?

$sometext = "The car ran over my dog"
needs to be filtered and reprinted as:
"The car ran over my dog"




Thanks :-)

This doesn't seem to work, have I done something wrong?



$sometext = "The car ran over my dog\n";
   $thread =  ereg_replace("[^[:alnum:][:space:]]", "", $sometext);
   echo $thread;

still prints:
The car ran over my dog


Thanks,
Clayton

 ?php
 $sometext = "The car ran over my dog";
 $thread =  ereg_replace("[^[:alnum:][:space:]]", "", $sometext);
 echo $thread
 ?

 will print what you asked - of course you may not want numbers but you
 get the idea.
 I do this check on all my user inputs to php scripts- I choose what is
 allowed not what to deny which makes it easier.

Strip everything which isn't in the list of allowed characters:
eregi_replace("[^[:alpha:]]", "", $sometext)

Look at the chr() function - figure out what the character is (number wise) and
then do an ereg_replace(chr(),'',$string) (from the hip - you can do a replace
with chr() on one of the replaces, I've done it before)

And you might also want to look at strtr() 
http://php.net/manual/en/function.strtr.php.  You could, I suppose, use 
it to substitute some character that you know would never legitimately 
appear in $sometext, then do a straight str_replace() on the string for all 
occurences of that character.
