Binary to Text and the other way around

Hello
I was wondering how you could convert binary code to text or text to binary.
I have no clue how I'd do this, and I'd like to know.
Thanks

If you mean from character to ASCII (A=65, etc.), then try these:
chr(), ord()

I just wrote this up real quick...

script:

<?php
error_reporting(0);


echo \"<html>\n\";
echo \"<body>\n\";
echo \"<pre>\n\";

$ascii = \"my string\";

echo \"<font size=\\"+1\\">\";
echo \"<b>String to Binary</b>\";
echo \"</font>\n\";
echo \"\n\";

echo \"ascii string:\n$ascii\n\";
echo \"\n\";

$binary = NULL;

for ($i=0, $letter=$ascii[$i]; $i<strlen($ascii); $letter=$ascii[++$i]) {
    printf(\"%s %3d %08d\n\", $letter, ord($letter), decbin(ord($letter)));
    $binary .= sprintf(\"%08d\", decbin(ord($letter)));
}

echo \"\n\";
echo \"binary string:\n\";
echo \"$binary\n\";
echo \"\n\";
echo \"\n\";


echo \"<font size=\\"+1\\">\";
echo \"<b>Binary to String</b>\";
echo \"</font>\n\";
echo \"\n\";

$string = NULL;

for ($i=0, $letter=substr($binary, $i, 8); ($i+8)<=strlen($binary); $i+=8, $letter=substr($binary, $i, 8)) {
    printf(\"%08d %3d %s\n\", $letter, bindec($letter), chr(bindec($letter)));
    $string .= sprintf(\"%s\", chr(bindec($letter)));
}

echo \"\n\";
echo \"ascii string:\n\";
echo \"$string\n\";
echo \"\n\";

echo \"\n\";
echo \"</pre>\n\";
echo \"</body>\n\";
echo \"</html>\n\";
?>

output:

wow. that's alarmingly cool. I can't think of a reason to use it, but I'm no programmer (clearly). Wow.
