Strip Function Not Working Correctly?

[adamjblakey]

Hi,

 

I have the following function which does not strip everything i need.

 

function StripAll($value) {

    $value = preg_replace('/[\r\n\t]+/', '', $value);
    $value = preg_replace("/[rn]+[st]*[rn]+/","n",$value);
    $value = stripslashes($value);
    $value = mysql_real_escape_string($value);
    $value = trim($value);
    $value = strip_tags($value);
    $value = str_replace(",", "", $value);
    $value = str_replace("'", "", $value);
    $value = str_replace(";", "", $value);
    $value = str_replace("&", " ", $value);
    $value = str_replace("(", " ", $value);
    $value = str_replace(")", " ", $value);

    return $value;

}

 

This still leaves in rn , full stops and brackets any ideas what is wrong with the function?

 

Cheers,

Adam

When using escape characters such as newlines (\r or \n) you should use double quotes. PHP will treat characters in single quotes as is.

 

Following line

$value = preg_replace('/[\r\n\t]+/', '', $value);

should be:

$value = preg_replace("/[\r\n\t]+/", '', $value);
