how to use char(xx) with ereg?

[Anon]

hello!
i am a total newbie, and would appreciate some help with this:

i want to search a string, $string for some chars. for example i want to know if "x" is in the string, but i want to use the charcode to do this.. char(xx) format.

like ereg ('char(xy)', $string); but the format is incorrect, how do i do this?

thanks

ech...
WHY!?!?!?!

but since you asked...
<?

//parse the string into ords...
for($i=0;$i<strlen($string);$i++) {
$ordinal .= ord(substr($string,$i,1);
}

if (ereg("'" . ord(x) . "|" . ord(y) . "'",$ordinal)) {
//do something...
}

?>

thanks for the reply 🙂

the purpose was actually to find if there are some "strange" chars in a string (POST string). Examples on http://hotwired.lycos.com/webmonkey/reference/special_characters/
I thought of doing a search in the string from char(195) - char(255) and if that happens, i replace some of those with the html code. Since that seldom happen, i don't want to run the code every time and skip it if it doesn't. Somehow i need to sort out if it includes those chars.

if there is any better way to do this, i would like to know. (like i said, i am a newbie =/..)

Ya, there's a function already made to handle that for you...

yeah🙂 thanks!

that solves almost all, only need to do two or three str_replace and everything is ok.

and, thanks for not pointing out a RTFM 😉
