DECHEX(3) 1 DECHEX(3)dechex - Decimal to hexadecimalSYNOPSIS
string dechex (int $number)
DESCRIPTION
Returns a string containing a hexadecimal representation of the given unsigned $number argument.
The largest number that can be converted is PHP_INT_MAX
* 2 + 1 (or -1): on 32-bit platforms, this will be 4294967295 in decimal, which results in dechex(3) returning ffffffff.
PARAMETERS
o $number
- The decimal value to convert. As PHP's integer type is signed, but dechex(3) deals with unsigned integers, negative integers
will be treated as though they were unsigned.
RETURN VALUES
Hexadecimal string representation of $number.
EXAMPLES
Example #1
dechex(3) example
<?php
echo dechex(10) . "
";
echo dechex(47);
?>
The above example will output:
a
2f
Example #2
dechex(3) example with large integers
<?php
// The output below assumes a 32-bit platform.
// Note that the output is the same for all values.
echo dechex(-1)."
";
echo dechex(PHP_INT_MAX * 2 + 1)."
";
echo dechex(pow(2, 32) - 1)."
