I tried the following and it didn't work:
<?
$i = base64_decode("\0\0\0A"); // I also tried
// $i = base64_decode("\0\0\0\0x41")
// and it didn't work either.
echo "***$i***\n";
?>

It was supposed to output:
***65***

I'm just starting with PHP, and I've been browsing the whole manual to find how to solve the following problem: 1. An integer number is internally represented in 4 bytes. Say, for instance, number 65 is represented by 0x00000041, that is the string "\0\0\0\0x41", and not the string "65". 2. How can I write this representation into a file and then read back it from the file? Do you have any idea about this? Thank you, Sergio.
