how can i transform from binar in decimal ????

which function i need to use ?

It would probably be meaningless to convert that binary string into a single decimal number, since it would be astronomical in size (and that might be an understatement). What is it supposed to represent?

You could break it down into 8-bit bytes (or 16- or 32-bit chunks if that makes more sense) via [man]str_split[/man] and then loop through each array element and apply [man]bin2dec/man to it, I suppose.

there can be some other information instead of just a number ...

something like 789632sdfg894isd//g'fd\=gfdgfd

The binary string you gave us is either 1 digit too long or 7 too short; either way, if you have a proper binary string (e.g. the number of digits is evenly divisble by 8) then you can use NogDog's suggestion of first using [man]str_split/man to split the binary into 8-bit chunks. You would then take each of these chunks, run them through [man]bin2dec/man to get them in decimal form, and finally use each of these decimals in the [man]chr/man function to convert the decimal into it's ASCII character equivalent.

Here's a table of ASCII characters and their decimal/octal/hexadecimal equivalents: http://www.asciitable.com/

wtg21_org

$content=explode("\n",$primary_info_c);
$i=0;
foreach ($content as $value) {

$rowrow = ("{$content[$i]}");
$binvalue = str_split($rowrow, "8");

//print_r($binvalue);

$j=0;
foreach ($binvalue as $bvalue) {

$bval = "{$binvalue[$j]}";

$result.= $bval." ";
$result1.= bindec($bval)." ";
$result2.=chr(bindec($bval))." ";

$j++;
}
$i++;
}

but i do not get the desired result

Well then you'll have to talk to whoever gave you the bogus binary string above; as I mentioned, it is not a standard string of ASCII-to-binary digits since that would require the number of digits to be evenly divisible by 8.
