hexdump() is a fantastic function for "dumping" packets or binary output from servers. See
the below link for more information.

A more simple version, bin2hex_string(), is a simple function to convert strings to readable hex
data.
<?php
function bin2hex_string ($data)
{
// Properly converts a binary string to a hexidecimal string
function bin2hex_nibble ($nibble)
{
// binary to hexidecimal, then uppercase, then 0 pads
return sprintf("%02s", strtoupper(bin2hex($nibble)));
}
// Explodes, applies bin2hex_nibble, then implodes with spacing.
return implode(' ', array_map('bin2hex_nibble', str_split($data)));
}
?>
Usage example:
<?php
$binarystr= "\xFF\xFF\xFF\xFF";
print bin2hex_string($binarystr);
?>
Output:
FF FF FF FF

Below is my function to convert a binary string into a readable hexidecimal representation.
Perfect for debugging stream or socket output.

{
// Properly converts a binary string to a hexidecimal string
function bin2hex_nibble ($nibble)
{
// binary to hexidecimal, then uppercase, then 0 pads
return sprintf("%02s", strtoupper(bin2hex($nibble)));
}
// Explodes, applies bin2hex_nibble, then implodes with spacing.
return implode(' ', array_map('bin2hex_nibble', str_split($data)));
}
?>
