 Marc,
 I have prepared a function to erase syntax from a input type=text
 But it won't erase $ in its output when I echo. What am I doing wrong?

 A post-reply would be real handy,
 Thanks,

snip much, more of same

Since you ask...  

You can save yourself a lot of trouble and a ton of wasted function calls 
by checking out a POSIX (ereg_*) or PCRE (preg_*) syntax tutorial.  When 
you want to match space or punctuation characters, character classes are a 
Good Thing(TM).  That whole loong block of code could be rendered with 
a single good, concise regex.  With the bonus of a lot less escaping.
