Description:
------------
http://php.net/manual/en/function.addcslashes.php

says 'A..z' escapes any tabs, line feeds, carriage
retuns. But 'A..z' escapes just upper and lower-case
letters and the [\]^_`.





Reproduce code:
---------------
<?php
for ($n = 0x00; $n < 0x80; $n++) {
    $c = chr($n);
    $escaped = addcslashes($c, 'A..z');
    if (strlen($escaped) == 2) {
        print ($n < 0x20 ? $escaped : $c);
    }
}
?>

Expected result:
----------------
\t\n\v\f\rABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz

Actual result:
--------------
ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Exactly. This is not a bug but a documentation problem.

http://php.net/manual/en/function.addcslashes.php

says ...

// All upper and lower-case letters will be escaped
// ... but so will the [\]^_` and any tabs, line
// feeds, carriage returns, etc.

I think it should be ...

// All upper and lower-case letters will be escaped
// ... but so will the [\]^_`.

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.

"All upper and lower-case letters will be escaped ... but so will the [\]^_`."
