    Hello

    I am using following code to allow characters like A to Z and numeric values like 0 to 9.

    $result = preg_replace('/[^a-zA-Z0-9_]/', '', $result);

    In case allow only numeric values I use

    $result = preg_replace("[^0-9]","", $string);

    Actually I need preg_replace to allow A-Z plus 0-9 and some special characters like < > / @ & and white spaces.

    Is there any way in preg_replace to do so?

    Any help please? Thanks!

    Perhaps it´s easier than you think:
    
$result = preg_replace("/[^!<>@&\/\sA-Za-z0-9_]/","", $string);
    PHP:
    just put the chars you want to not remove in the [] and you be fine. You have to escape the / with \/ otherwise it will change the regex.
