PHP convert an octal characters to string

Title is pretty much self explanatory...
How do I echo an octal string ?
I tried :

<?php
echo '\047\131\145\141\162\040\072\040\047'.'<br>';
echo decoct('\047\131\145\141\162\040\072\040\047').'<br>';
echo decoct('047').decoct('131').decoct('145').decoct('141').decoct('162').decoct('040').decoct('072'),decoct('040').decoct('047').'<br>';
?>

but nothing is working for me....
I'm quite sure that some small tweak is needed here but... which one?
Thanks!

This a backslash escaped string, so use stripcslashes() to un-escape, like this:

$escaped = '\047\131\145\141\162\040\072\040\047'.'<br>';
$unescaped = stripcslashes($escaped);
echo $unescaped;

Result:

'Year : '<br>

This may help

function convertOctalToCharacter($octal) {
    return chr(octdec($octal[1]));
}

For a mass-tokenizing of strings with octals, this regex-processing may become handy too:

$string = preg_replace_callback('/\\\\([0-7]{1,3})/', 'convertOctalToCharacter', $string);

Escape sequences are only processed inside double quoted strings, not single-quoted strings.

echo "\047\131\145\141\162\040\072\040\047".'<br>';
