How to remove special character?

[medica]

I want to remove special charcters, say ' ( ) : ?

only remain letters, numbers, and blank space

[kdd]

What language? I'm assuming PHP, then:



$arr = array ( "'" , "(" , ")" , ":" , "?" );
$newStr = str_replace ( $arr , "" , $oldStr );
But can anyone else do this same thing using trim, ltrim, and rtrim functions. I'd like to see that. Thanks! :)


PHP's array and string libraries are so huge, it's hard to remember all this stuff. It's like you have to keep one window open just for that!

use regex instead, it's more effective since you're providing a white list as opposed to a black list


ereg_replace('[^A-Za-z0-9 ]','',$str);


example


<?php
$str = '()-abc123 d 35#$#%^^&';
$str = ereg_replace('[^A-Za-z0-9 ]','',$str);
echo $str;
?>


output


abc123 d 35
