Binary to text


Use these two useful functions to change text into binary and vice versa.

function bin2text($bin_str)
{
$text_str = '';
$chars = explode("\n", chunk_split(str_replace("\n", '', $bin_str), 8));
$_I = count($chars);
for(
$i = 0; $i < $_I; $text_str .= chr(bindec($chars[$i])), $i);
return
$text_str;
}

function
text2bin($txt_str)
{
$len = strlen($txt_str);
$bin = '';
for(
$i = 0; $i < $len; $i)
{
$bin .= strlen(decbin(ord($txt_str[$i]))) < 8 ? str_pad(decbin(ord($txt_str[$i])), 8, 0, STR_PAD_LEFT) : decbin(ord($txt_str[$i]));
}
return
$bin;
}
?>
