Hello, I use this code:


$a = "&&&&&& a b c d e f g";
$b = ereg_replace ("&", "%26", $a);

echo $b;

to subtitute every "&" occurrence in $a.

What if I want to change other occurrences of other chars at the same
time?
Say, I want to substitute "?", "*" and "°"...

How can I do?

Maybe you should look up the built in function urlencode

http://uk.php.net/manual/en/function.urlencode.php

Sorry for my example... but I need exactly what I asked, not url-
encoding :-)

hi

it's not clear from your post what exactly you're after

maybe strtr function s you

$trans = array(
'&' => "%26",
'?' => "%3F",
'%' => "%25",
);

echo strtr("a & b ? c % d", $trans);

No regex needed -- just good old str_replace():

$b = str_replace(array('&', '?', '*'), '%26', $a);

Thank you all!
