PHP中Escape加密函数

function escape($str) {
    $sublen = strlen ( $str );
    $retrunString = "";
    for($i = 0; $i < $sublen; $i ++) {
        if (ord ( $str [$i] ) >= 127) {
            $tmpString = bin2hex ( iconv ( "gb2312", "ucs-2", substr ( $str, $i, 2 ) ) );
            $retrunString .= "%u" . $tmpString;
            $i ++;
        } else {
            $retrunString .= "%" . dechex ( ord ( $str [$i] ) );
        }
    }
    return $retrunString;
}

ASP中Escape加密函数

Function Escape(str) 
    dim i,s,c,a 
    s="" 
    For i=1 to Len(str) 
        c=Mid(str,i,1) 
        a=ASCW(c) 
        If (a>=48 and a<=57) or (a>=65 and a<=90) or (a>=97 and a<=122) Then 
            s = s & c 
        ElseIf InStr("@*_+-./",c)>0 Then 
            s = s & c 
        ElseIf a>0 and a<16 Then 
            s = s & "%0" & Hex(a) 
        ElseIf a>=16 and a<256 Then 
            s = s & "%" & Hex(a) 
        Else 
            s = s & "%u" & Hex(a) 
        End If 
    Next 
    Escape = s 
End Function
