Cant escape a string with addcslashes()

Question

I am trying ot learn how to escape simple characters. I print the ASCII of the character >. But when I print it after using the function addcslashes..nothing is escaped. Why is that?

     $da=ord('>'); 
     echo $da."<br/>";
     $not_escaped="><?";
      $escaped = addcslashes($not_escaped, "\61...\64");
      echo  $escaped;

I followed their documentations..but my example above doesnt work. Thye also use 2 seperators !@ between the range of ASCII number range..what does it mean?

$escaped = addcslashes($not_escaped, "\0..\37!@\177..\377");

The ASCII codes in the $charlist are octal, not decimal. So to escape ">" (decimal: 62, octal: 76), use this code:

$escaped = addcslashes($not_escaped, "\76");

For a range, use two dots and not three ('a..z', not 'a...z').

Multiple ranges: `$escaped = addcslashes($not_escaped, "[email protected]"); // escape a-c and k-m` – pencil Feb 18 '12 at 13:11
what about characters between 32 and 126.. is tehir representation is decimal – BlackFire27 Feb 18 '12 at 13:13
No, all the ASCII codes should be octal. ;) > they are converted in C-like style, [...] to octal representation. – pencil Feb 18 '12 at 13:19
lol..why the hell did they say that: characters with ASCII codes lower than 32 and higher than 126 converted to octal representation. ... if all of them should be ocatal? – BlackFire27 Feb 18 '12 at 13:20
