psSanitizePath()
Sanitize a string used for file/paths names

Description:

This removes all chrs that can be used by a hacker to obtain a file
from your server by providing a bad parameter in a file request in a url parameter

Note: this always pulls off leading "/"

Usage:

$str = psSanitizePath($strPath,{$pre});
set $pre to true allow starting with /

Example:


	$str = psStrNumOnly("../../../../etc/passwd"); // returns "etc/passwd"

Code:

function psSanitizePath($str,$pre=false)
{
	$str = str_replace("\"","",$str);
	$str = str_replace("`","",$str);
	$str = str_replace("..","",$str);
	$str = str_replace("./","",$str);
	$str = str_replace(":","",$str);
	if (substr($str,0,1) == "/" && $pre == false) { $str = substr($str,1); }
	return $str;
}

Changlelog:

03/09/2016 Allow use of preceeding '/' by passing $pre = true
